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

 1   public void ProcessRequest(HttpContext context)
 2         {
 3             context.Response.ContentType = "text/html";
 4             BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
 5            List<UserInfo>list= UserInfoService.GetEntityList();
 6            // List<UserInfo>list=UserInfoService.GetEntityList();
 7             StringBuilder sb = new StringBuilder();
 8             foreach (UserInfo userInfo in list)
 9             {
10                 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);
11 } 12 string filePath = context.Request.MapPath("UserInfoList.html"); 13 string fileContent = File.ReadAllText(filePath); 14 fileContent= fileContent.Replace("$tbody",sb.ToString()); 15 context.Response.Write(fileContent); 16 }

 

修改

 1  public void ProcessRequest(HttpContext context)
 2         {
 3             context.Response.ContentType = "text/html";
 4             int id;
 5             if (int.TryParse(context.Request.QueryString["id"], out id))
 6             {
 7                 //1从Bll 里面获取数据
 8                 BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
 9 
10                 UserInfo userInfo =UserInfoService.GetModel(id);
11                 //2创建文件名和文件路径
12                 string filePath = context.Request.MapPath("Edit.html");
13                 string fileContent = File.ReadAllText(filePath);
14                //3 再替换
15                fileContent= fileContent.Replace("$txtName",userInfo.UserName).Replace("$txtPwd",userInfo.UserPass).Replace("$txtEmail",userInfo.Email).Replace("$txtRegTime",userInfo.RegTime.ToString()).Replace("$txtId",userInfo.ID.ToString());
16                context.Response.Write(fileContent);
17             }
18         }

Edit.html类

1
<form method="post" action="ProcessEdit.ashx"> 2 <input type="hidden" name="txtId" value="$txtId" /> 3 <table> 4 <tr><td>用户名</td><td><input type="text" name="txtName" value="$txtName" /></td></tr> 5 <tr><td>密码</td><td><input type="text" name="txtPwd" value="$txtPwd" /></td></tr> 6 <!-- <tr><td>邮箱</td><td><input type="text" name="txtEmail" value="$txtEmail"/></td></tr> 7 <tr><td>日期时间</td><td><input type="text" name="txtRegTime" value="$txtRegTime"/></td></tr>--> 8 <tr><td colspan="4"><input type="submit" value="修改用户" /></td></tr> 9 </table> 10 </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

 1   public void ProcessRequest(HttpContext context)
 2         {
 3             context.Response.ContentType = "text/html";
 4             int id;
 5             if (int.TryParse(context.Request.QueryString["id"], out id))
 6             {
 7                 BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
 8                 UserInfo userInfo=UserInfoService.GetModel(id);
 9                 string filePath = context.Request.MapPath("ShowDetail.html");
10                 string fileContent = File.ReadAllText(filePath);
11                 fileContent = fileContent.Replace("$name", userInfo.UserName).Replace("$pwd",userInfo.UserPass);
12                 context.Response.Write(fileContent);
13             }
14         }
<table>
        <tr><td>用户名</td><td>$name</td></tr>
            <tr><td>密码</td><td>$pwd</td></tr>
    </table>
