Ashx增删改查_动软

1.首先展示列表 ashx 讲究的是个替换 这些就是属于ashx麻烦的地方

   public void ProcessRequest(HttpContext context)
         {
             context.Response.ContentType = "text/html";
             BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
            List<UserInfo>list= UserInfoService.GetEntityList();
            // List<UserInfo>list=UserInfoService.GetEntityList();
             StringBuilder sb = new StringBuilder();
             foreach (UserInfo userInfo in list)
             {
                 sb.AppendFormat("<tr><td>{0}</td><td>{1}</td><td>{2}</td><td>{3}</td><td>{4}</td><td
><a href='ShowDetail.ashx?id={5}'>详细</a></td><td>删除</td><td><a href='Edit.ashx?id={5}'>修改</a></td></tr>",
 userInfo.ID, userInfo.UserName, userInfo.UserPass, userInfo.RegTime.ToShortDateString(), userInfo.Email, userInfo.ID);
             }
             string filePath = context.Request.MapPath("UserInfoList.html");
             string fileContent = File.ReadAllText(filePath);
            fileContent= fileContent.Replace("$tbody",sb.ToString());
            context.Response.Write(fileContent);
         }

修改

  public void ProcessRequest(HttpContext context)
         {
             context.Response.ContentType = "text/html";
             int id;
             if (int.TryParse(context.Request.QueryString["id"], out id))
             {
                 //1从Bll 里面获取数据
                 BLL.UserInfoService UserInfoService = new BLL.UserInfoService();

                 UserInfo userInfo =UserInfoService.GetModel(id);
                 //2创建文件名和文件路径
                 string filePath = context.Request.MapPath("Edit.html");
                 string fileContent = File.ReadAllText(filePath);
                //3 再替换
                fileContent= fileContent.Replace("$txtName",userInfo.UserName).Replace("$txtPwd",userInfo.UserPass).Replace("$txtEmail",userInfo.Email).Replace("$txtRegTime",userInfo.RegTime.ToString()).Replace("$txtId",userInfo.ID.ToString());
                context.Response.Write(fileContent);
             }
         }

Edit.html类

1  <form method="post" action="ProcessEdit.ashx">
       <input type="hidden" name="txtId" value="$txtId" />
     <table>
         <tr><td>用户名</td><td><input type="text" name="txtName" value="$txtName" /></td></tr>
           <tr><td>密码</td><td><input type="text" name="txtPwd" value="$txtPwd" /></td></tr>
        <!--   <tr><td>邮箱</td><td><input type="text" name="txtEmail"  value="$txtEmail"/></td></tr>
            <tr><td>日期时间</td><td><input type="text" name="txtRegTime"  value="$txtRegTime"/></td></tr>-->
         <tr><td colspan=""><input type="submit" value="修改用户" /></td></tr>
     </table>
         </form>

ProcessEdit.ashx类

public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
          //  UserInfo userInfo = new UserInfo();
            //userInfo.UserName=context.Request.Form["txtName"];
            //userInfo.UserPass=context.Request.Form["txtPwd"];
            //userInfo.RegTime = Convert.ToDateTime(context.Request.Form["txtRegTime"]);
            //userInfo.Email=context.Request.Form["txtEmail"];
            int id=Convert.ToInt32(context.Request.Form["txtId"]);
            BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
            UserInfo userInfo=UserInfoService.GetModel(id);//查询一下，然后再修改,
            userInfo.UserName = context.Request.Form["txtName"];
            userInfo.UserPass = context.Request.Form["txtPwd"];
            if (UserInfoService.UpdateEntity(userInfo))
            {
                context.Response.Redirect("UserInfoList.ashx");
            }
            else
            {
                context.Response.Write("修改失败");
            }

        }

展示

   public void ProcessRequest(HttpContext context)
         {
             context.Response.ContentType = "text/html";
             int id;
             if (int.TryParse(context.Request.QueryString["id"], out id))
             {
                 BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
                 UserInfo userInfo=UserInfoService.GetModel(id);
                 string filePath = context.Request.MapPath("ShowDetail.html");
                 string fileContent = File.ReadAllText(filePath);
                 fileContent = fileContent.Replace("$name", userInfo.UserName).Replace("$pwd",userInfo.UserPass);
                 context.Response.Write(fileContent);
             }
         }

<table>
        <tr><td>用户名</td><td>$name</td></tr>
            <tr><td>密码</td><td>$pwd</td></tr>
    </table>
