sharepoint知识点总结

{
users.Add(value.User);
}
else
{
SPGroup group = web.Groups.GetByID(value.LookupId);
groups.Add(group);
foreach (SPUser user in group.Users)
{
users.Add(user);
}
}
}

SPFieldLookupValueCollection  values = (SPFieldLookupValueCollection )item["Users"];

SPFieldLookupValueCollection values = item["Users "].ToString();
string initUsers = "";
foreach (SPFieldLookupValue value in values)
{

int valueID = value.LookupId;
string valueTitle = value.LookupValue;

}

代码启动工作流

          获取spworkflowmanager 获取spworkflowassociation，针对一个item启动

向Item中添加附件

if (fileUploadAttach.HasFile)
                {
                    Stream stream = fileUploadAttach.PostedFile.InputStream;
                    stream.Position = 0;
                    byte[] buffer = new byte[stream.Length];
                    stream.Read(buffer, 0, (int)stream.Length);
                    itemNew.Attachments.Add(fileUploadAttach.PostedFile.FileName, buffer);
                    itemNew.Update();
                    itemNew.ParentList.Update();
                    stream.Close();
                }

CAML查找Lookup型

     <FieldRef Name="GMP" LookupId="TRUE"/>

         <Value Type="Lookup">1</Value>

用户型

"<FieldRef Name=""User"" LookupId=""TRUE""/>" +

"<Value Type=""User"">" + user.ID + "</Value>" +

WEB页面显示word

          如果想让web页面显示出word文档要加

Response.ContentType = "application/msword";

Response.AddHeader("Content-Disposition","attachment;filename=" +

HttpUtility.UrlEncode(file.FILENAME).Replace("+","%20"));// 防止乱码

Response.Charset="UTF-8";

Response.ContentEncoding=System.Text.Encoding.Default;

Response.BinaryWrite(文件流);

Response.End();

多文件上传

          SPFileCollection destFiles =

siteCollection.AllWebs["Destination_Site"]

.Folders["Destination_DocLib"].Files;

foreach (SPFile srcFile in srcFolder.Files)

{

if (srcFile.TimeLastModified <

Convert.ToDateTime("12/5/2002 12:00:00 AM"))

{

string destURL = destFiles.Folder.Url + "/" + srcFile.Name;

byte[] binFile = srcFile.OpenBinary();

destFiles.Add(destURL, binFile, true);

}

}

工作流中权限

          先HybridDictionary一个对象叫task1permission，然后task1permission.Add(taskProps.AssignedTo, SPRoleType.Contributor），最后将task1permission赋值给task的SpecialPermissions

检查权限

public void CheckPermissions (SPBasePermissions permissionMask)

检查当前用户是否有permissionMask的权限，如果没有返回一个UnauthorizedAccessException的异常。

Bool havePermission = SPList.DoesUserHavePermissions(SPBasePermissions permissionMask)

添加权限

SPList DTTasks = web2.Lists["Document Tasks"];

SPRoleAssignment roleAssignForMember = new SPRoleAssignment((SPPrincipal)newGroup); //为newGroup这个组分配权限

SPRoleDefinition roleDefForMemberr = web2.RoleDefinitions["DTMembers"];

roleAssignForMember.RoleDefinitionBindings.Add(roleDefForMemberr);

if (!DTTasks.hasUniqueRoleAssignments)//如文件夹没有独立的权限

{

DTTasks.BreakRoleInheritance(false);      //删除文件夹继承的权限 true删除的同时继承false删除的同时不继承

}

DTTasks.RoleAssignments.Add(roleAssignForMember);

TTasks.Update();

无法查询文件夹下的item，只能查找根目录的解决办法：

query.ViewAttributes = " Scope='Recursive' "

	Member name	Description
	Default	Show only the files and subfolders of a specific folder.
	FilesOnly	Show only the files of a specific folder.
	Recursive	Show all files of all folders.
	RecursiveAll	Show all files and all subfolders of all folders.

The SPViewScope enumeration is used with the Scope property of the SPView class.

EventHandler中的Adding Updating等操作如何赋值

public override void ItemAdding(SPItemEventProperties properties)

{
    // Demo1: 在新建时取用户输入的值并作修改
    string newValue = "新的值是：" + properties.AfterProperties["Title"].ToString();
    properties.AfterProperties.ChangedProperties.Add("Title", newValue);
}

如何从SPAttachmentCollection中获取到SPfile

SPAttachmentCollection attachments = item.Attachments;

if (attachments.Count > 0)

{

for (int i = 0; i < attachments.Count; i++)

{

string url = attachments.UrlPrefix + attachments[i];//得到附件的共同前缀再加上附件的名称

SPFile file = web.GetFile(url);

string customerName = item["Customer Name"].ToString().Split('#')[1];

file.CopyTo(properties.WebUrl + "/CRM Document/" + customerName + "/04 Customer Scoring/" + attachments[i], true);

}

如何查看SharePoint未知错误

在MOSS开发自定义功能后，出现错误页面只显示“出现未知错误”的提示，查看很不方面，通过下面方法就可以直接在出错页面查看错误信息。

修改Web应用程序根目录上的Web.config文件中的两个地方：
查找以下位置并更改即可(红色为更改前后的值)
一、MaxControls="200" CallStack="false"   改为  MaxControls="200" CallStack="true"
二、customErrors mode="On"  改为  customErrors mode="Off"

Webpart出错，无法打开页面，contents=1 ,会转到webpart管理页面，把出问题的删掉

在URL后面加入“?&toolpaneview=2”打开设计页

或者加“DisplayMode=Design”

http://cnsh-10vms1/_layouts/spcontnt.aspx?&url=/_catalogs/wp/forms/editForm.aspx这页面是维护页面

“超链接或图片”类型栏的值，对应的对象模型为SPFieldUrl和SPFieldUrlValue，可以这样读取：

SPFieldUrlValue value = new SPFieldUrlValue(item["URL"].ToString());
       Console.WriteLine(value.Description);
       Console.WriteLine(value.Url);

或

SPFieldUrl fieldUrl = (SPFieldUrl)item.Fields["URL"];
SPFieldUrlValue value = (SPFieldUrlValue)fieldUrl.GetFieldValue(item["URL"].ToString());
Console.WriteLine(value.Description);
Console.WriteLine(value.Url);

赋值

SPFieldUrl fieldUrl = (SPFieldUrl)supplierNew.Fields[dgi.Cells[0].Text];

SPFieldUrlValue fieldUrlValue = new SPFieldUrlValue();

fieldUrlValue.Url = web.Url + "/" + supplierDocument.RootFolder.Url + "/" + supplierNew["Title"].ToString() + "-" + supplierNew.ID;

fieldUrlValue.Description = dgi.Cells[0].Text;

supplierNew[dgi.Cells[0].Text] = fieldUrlValue;

将子网站移动到主网站？？？

修改子网站下的网站栏到网站集下解决了，直接到WSS_Content数据库里面，修改表ContentTypes的Scope字段，特别方便，暂时没发现出错误～

SharePoint中LookUp字段的使用

赋值

如何在代码中使用lookup字段

对于lookup字段在可视界面时，感觉挺方便，但是在写代码的时候，对它进行赋值的时候，就感觉很麻烦。不知道哪位高手对这个赋值有更好的方法，谢谢。
方法一(听11同学说的)
SPFieldLookupValueCollection lookupValues;

lookupValues = (SPFieldLookupValueCollection)listItem["MyLookupField"];

lookupValues.Add(new SPFieldLookupValue(1, "SomeLookupValue"));
listItem["MyLookupField"] = lookupValues;

listItem.Update();

这方法感觉赋值就是受罪，写这么多代码。
方法二。直接用
listItem["MyLookupField"] =1,2,3
但这此方法要知道字符串所对应的Id。,有什么最有效的方法。。请教高手

实际使用如下代码(经过测试):

 

                                 SPWeb web = SPContext.Current.Web;

SPList customerList = web.Lists["Customer"];

SPQuery query = new SPQuery();

query.Query = "<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>" + DropDownList1.SelectedItem.Text + "</Value></Eq></Where>";

SPListItemCollection customerC = customerList.GetItems(query);

int cu1 = customerC[0].ID;

SPList projectList = web.Lists["Project"];

SPListItem projectNew = projectList.Items.Add();

projectNew["Customer"] = cu1;

projectNew["Title"] = txtboxProjectName.Text;

projectNew.Update();

LookUpCollection的赋值

SPFieldLookupValueCollection lvsGDE = new SPFieldLookupValueCollection();

foreach (ListItem item in lbGDECurrent.Items) //lbGDECurrent为下拉框

{

SPFieldLookupValue lvGDE = new SPFieldLookupValue();

lvGDE.LookupId = int.Parse(item.Value);

lvsGDE.Add(lvGDE);

}

Item[“Lookups”] = lvsGDE;

LookUp和User的读取

    如果LookUp不允许多选的时候,Item["LookUp"]得到的是一个string

String C = (item["Created By"] == null) ? "" : item["Created By"].ToString().Remove(0, item["Created By"].ToString().IndexOf(";#") + 2);

否则是一个SPFieldLookUpValueCollection

用户类型为SPFieldUserValueCollection

List<SPUser> Users = new List<SPUser>();
            List<SPGroup> Groups = new List<SPGroup>();

using (SPSite Site = new SPSite("http://windbell"))
             {
                SPWeb Web = Site.RootWeb;
                SPList List = Web.Lists["测试列表"];
                SPItem Item = List.Items[0];

SPFieldUserValueCollection Values = (SPFieldUserValueCollection)Item["用户和用户组"];

foreach (SPFieldUserValue Value in Values)
                 {
                    if (User != null)
                     {
                        SPUser User = Value.User;
                        Users.Add(User);
                    }
                    else
                     {
                        SPGroup Group = Web.Groups.GetByID(Value.LookupId);
                        Groups.Add(Group);
                        Users.AddRange(Group.Users);
                    }
                }
            }

 

定义一个Group

SPGroupCollection groups = oWebsite.SiteGroups;

SPUser user = oWebsite.Users["xxx""xxxxxx"];

SPMember member = oWebsite.Users["xxxxx""xxx"];

groups.Add("TestGroup", member, user, "Description");

将一个Group分配进一个Role

if (SPWeb.HasUniqueRoleAssignments == true)//web是否有自己的角色分配，有True
                    {
                        SPWeb.AllowUnsafeUpdates = true;

SPRoleAssignment roleAssign = new SPRoleAssignment((SPPrincipal)SPSite.RootWeb.SiteGroups["Style Resource Readers"]);

SPRoleDefinition roleDef = SPWeb.RoleDefinitions["Open Access"];
                        roleAssign.RoleDefinitionBindings.Add(roleDef);

SPWeb.RoleAssignments.Add(roleAssign);
                    }

读取User Profile

ServerContext spcontext2 = ServerContext.GetContext(site);

UserProfileManager profileManager = new UserProfileManager(spcontext2);

string userName = member.Name;

SPListItem newMember = projectMember.Items.Add();

newMember["User Name"] = member.Name;

newMember["Project"] = Project;

newMember["Group"] = newGroup.Name;

newMember["E-mail Address"] = member.Email;

if (profileManager.UserExists(userName))

{

UserProfile profile = profileManager.GetUserProfile(userName);

newMember["Business Phone"] = profile["BusinessPhone"].Value;

newMember["Mobile Phone"] = profile["CellPhone"].Value;

newMember["Fax"] = profile["Fax"].Value;

//newMember["Notes"] = member[PropertyConstants.CellPhone].

newMember["SkypeMSN"] = profile["SkypeMSN"].Value;

newMember["Principalship"] = profile["Principalship"].Value;

newMember["Location"] = profile["Location"].Value;

}

newMember.Update();

关闭EventHandler

this.DisableEventFiring();//关闭EventHandler，防止多重触发

//save changes

addedItem.Update();

this.EnableEventFiring();

workflowProperties.OriginatorUser得到当前workflow instance的发起者

workflowProperties.Item不就可以直接拿到SPListItem

SharePoint中访问AD

System.DictionaryService
