ASP.NET如果根URL包含查询字符串，则在重定向时将其传递给default.aspx

Question

Is there any way that I can preserve a query string and pass it to the default.aspx; For example:

http://www.example.com/?test=123

becomes

http://www.example.com/Default.aspx?test=123

Thanks in advance!

Yes you can. You could use Request.QueryString["test"] to get the value from query string and pass it to the other page using

if(Request.QueryString["test"] != null)
{
      Response.Redirect("~/Default.aspx?test=" + Request.QueryString["test"].ToString())
}

Do this in Session_Start method of Global.asax.cs

Or if you want to pass the entire query string instead of one value just use Request.QueryString.ToString()
