使用QueryString [英] Using QueryString

问题描述

非常感谢您的即时回复.我将更清楚，更详细地说明我的问题

这是我在第一页中的代码.

Hi,
Thanks a lot for your immediate response. I will explain my problem clearly and in more detail

this is my code in first page.

protected void btnLogin_Click(object sender, EventArgs e)
    {
        string pusername = NameTextBox.Text;
        Response.Redirect("~/OrderForm.aspx?username=" + pusername);
    }

这是我在第二页中的代码

this is my code in second page

protected void Page_Load(object sender, EventArgs e)
  {
      if (!IsPostBack)
      {
          string username = Request.QueryString["pusername"];
          lblWelcome.Text += "Welcome," + username ;
      }
  }

当我尝试在第二页中获取此变量pusername时，我没有得到它.你能告诉我可能是什么错误吗?如果我尝试使用其在查询字符串中的位置来检索此值，则它将起作用.
请像我提到的那样告诉我如何使用变量.

when I try to get this variable pusername in the second page, I am not getting it. Can you please tell what could be the error. If i try it retrieve this values using their position in the querystring then it works.
Please tell me how to do with variables as I mentioned.

推荐答案

而不是这样:

Instead of this:

string username = Request.QueryString["pusername"];

为此:

do this:

string username = Request.QueryString["username"];

您的querystring变量是''用户名''& "pusername"是用于在上一页中分配值的变量.

Your querystring variable is ''username'' & ''pusername'' is a variable used to assign value in previous page.
