如何从ASP中的查询字符串中获取数据? [英] How do I get data from the query string in asp?

问题描述

我正在为一个IT类的项目工作，我需要在php页面的查询字符串中传递一个值，然后将其读入ASP页面的一个隐藏字段中.

我当前正在传递该参数从php页面到ASP都很好，但是一般来说，我对.NET还是很陌生.如何从字符串中获取数据并将其放入C#中的变量中?例如，如果URL是 blah.com/upload?username=washington ，我将如何获取"washington"并将其保存到隐藏字段中?多谢.

I am working on a project for an IT class where I need to pass in a value on the query string in a php page and read it into a hidden field on an ASP page.

I currently am passing the parameter fine from the php page to ASP, but I am pretty new to .NET in general. How do I get the data out of the string and into a variable in C#? For example, if the url is blah.com/upload?username=washington, how would I get "washington" and save it into a hidden field? Thanks a ton.

推荐答案

您可以在aspx文件中添加隐藏字段:

You can add a hidden field in your aspx file:

<asp:HiddenField ID="username" runat="server" />

然后在您的代码后面，从request参数中填充它:

And in your code behind populate it from the request parameter:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        username.Value = Request["username"];
    }
}
