LinkBut​​ton中的查询字符串不起作用 [英] Query String in LinkButton not working

问题描述

嗨

在我的aspx页面中我已经在page_load中绑定了我的listview，如下所示，我在页面中也有Linkbutton，在此Linkbutton的click事件中我添加了这个来获取UID并使用UID重定向到另一个名为UserAds.aspx的页面，根据查询sting绑定UserAds.aspx中的anothor ListView但是没有任何事情发生qurey字符串不保存UID，我可以使用会话但是没有用作url应该处理用户ID

  protected   void  LinkBut​​ton1_Click（ object  sender，EventArgs e）
 {
 
 
 Response.Redirect（  UserAds.aspx？USRST + adsusrnmlbl.Text ）; 
 
} 

 SqlConnection shwadsone =  new  SqlConnection（cs）; 
 {
 
 
  //  打开连接 
 shwadsone.Open（）; 
 SqlCommand adsdeCM =  new  SqlCommand（）; 
  //  构建数据适配器 
  string  adsdetSqlSelect =  @  SELECT AD。[AdsID] 
，AD。[UID ] 
，AD。[部分] 
，AD。[类别] 
，AD。[地址] 
，UI。[Logo]，[Img]，[TeleNum]， [电子邮件] 
 FROM [ads] as AD 
 JOIN 
 UserInfo as UI 
 ON AD。[UID] = UI。[UID] 
其中AD.AdsID = @AID; 
 
 
 adsdeCM.CommandText = adsdetSqlSelect; 
 adsdeCM.CommandType = CommandType.Text; 
 adsdeCM.Connection = shwadsone; 
 adsdeCM.Parameters.AddWithValue（  AID，Request.QueryString [  AID]）; 
 SqlDataReader adsdetDR; 
 adsdetDR = adsdeCM.ExecuteReader（）; 
 
  if （adsdetDR.Read（））
 {
 
 adsusrnmlbl.Text = adsdetDR [< span class =code-string>  UID]。ToString（）; 
 adssectlbl.Text = adsdetDR [  Section]。ToString（）; 
 adscatelbl.Text = adsdetDR [ 类别]。ToString（）; 
 adsdetaddrslbl.Text = adsdetDR [  Address]。ToString（）; 
} 
} 

解决方案

您必须仔细了解应如何构建URL编码（查询字符串）。 ..

 Response.Redirect（  UserAds.aspx？USRST  =  + adsusrnmlbl 。文本）;  //  寻找等号（=）!!!

                    Response.Redirect("UserAds.aspx?USRST" + adsusrnmlbl.Text);

        }

SqlConnection shwadsone = new SqlConnection(cs);
            {
                

                // Open your connection
                shwadsone.Open();
                SqlCommand adsdeCM = new SqlCommand();
                // Build your data adapter
                string adsdetSqlSelect = @"SELECT AD.[AdsID]
,AD.[UID]
,AD.[Section]
,AD.[Category]
,AD.[Address] 
,UI.[Logo],[Img],[TeleNum],[Email] 
FROM [ads] as AD
JOIN
UserInfo as UI
ON AD.[UID] = UI.[UID]
where AD.AdsID = @AID ";

               
                adsdeCM.CommandText = adsdetSqlSelect;
                adsdeCM.CommandType = CommandType.Text;
                adsdeCM.Connection = shwadsone;
                adsdeCM.Parameters.AddWithValue("AID", Request.QueryString["AID"]);
                SqlDataReader adsdetDR;
                adsdetDR = adsdeCM.ExecuteReader();
                
                if (adsdetDR.Read())
                {

                  adsusrnmlbl.Text = adsdetDR["UID"].ToString();
                  adssectlbl.Text = adsdetDR["Section"].ToString();
                  adscatelbl.Text = adsdetDR["Category"].ToString();
                  adsdetaddrslbl.Text = adsdetDR["Address"].ToString();
                    }
                }

解决方案

You have to learn carefully how URL encoding (query string) should be built...
http://en.wikipedia.org/wiki/Query_string[^]

Response.Redirect("UserAds.aspx?USRST=" + adsusrnmlbl.Text); // look for the equal sign (=)!!!
