SharePoint 服务器端对象模型操作文档库(上传/授权/查看权限)

　　简介：上传文档到文档库，并对项目级授权，查看项目级权限方法

        //在列表根目录下创建文件夹

public static string CreatFolderToSPDocLib(string strFolderName, string strDocLibName)

{

string FolderPath = string.Empty;

try

{

using (SPSite site = new SPSite(SiteUrl))

{

using (SPWeb web = site.OpenWeb())

{

web.AllowUnsafeUpdates = true;

SPListCollection lists = web.GetListsOfType(SPBaseType.DocumentLibrary);

lists.IncludeRootFolder = true;

SPList list = lists[strDocLibName];

list.EnableFolderCreation = true;

SPListItem item = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, strFolderName);

item.Update();

list.Update();

FolderPath = item["FileRef"].ToString();

web.AllowUnsafeUpdates = false;

}

}

}

catch

{

}

return FolderPath;

}

　　//上传文件到文件夹，并授权给相关用户

public static bool UpLoadFileToFolder(byte[] FileStream, string FileName, string FolderPath, string allLoginName)

{

try

{

using (SPSite site = new SPSite(SiteUrl))

{

using (SPWeb web = site.OpenWeb())

{

web.AllowUnsafeUpdates = true;

SPFolder folder = web.GetFolder(FolderPath);

SPListItem listItem = folder.Files.Add(FileName, FileStream).Item;

//断开原来列表项所继承的权限,使其可以设置独立权限

listItem.BreakRoleInheritance(true);

//将原来所继承的权限通通移除

foreach (SPRoleAssignment roleAssignment in listItem.RoleAssignments)

{

roleAssignment.RoleDefinitionBindings.RemoveAll();

roleAssignment.Update();

listItem.Update();

}

//获取将要设置权限的用户

SPUser myUser = web.EnsureUser(allLoginName);

//定义权限分配

SPRoleAssignment myRoleAssignment = new SPRoleAssignment(myUser.LoginName, myUser.Email, myUser.Name, myUser.Notes);

//绑定设置的权限

myRoleAssignment.RoleDefinitionBindings.Add(web.RoleDefinitions.GetByType(SPRoleType.Reader));

//把这个权限加到我们的列表中

listItem.RoleAssignments.Add(myRoleAssignment);

listItem.Update();

web.AllowUnsafeUpdates = false;

return true;

}

}

}

catch

{

return false;

}

}

        //通过ID获取列表项

public static string GetRoleAssignmentsOfSPListItem(string ListName, int ItemID)

{

string reValue = string.Empty;

try

{

using (SPSite site = new SPSite(SiteUrl))

{

using (SPWeb web = site.OpenWeb())

{

web.AllowUnsafeUpdates = true;

SPList list = web.Lists[ListName];

SPListItem item = list.Items.GetItemById(ItemID);

SPRoleAssignmentCollection Rolecoll = item.RoleAssignments;

foreach (SPRoleAssignment role in Rolecoll)

{

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

{

reValue += (role.Member.LoginName + ":" + role.RoleDefinitionBindings[i].Name + ":" + role.RoleDefinitionBindings[i].BasePermissions.ToString());

}

}

web.AllowUnsafeUpdates = false;

}

}

}

catch

{

}

return reValue;

}
