How to pass '#' in query string

问题

I want to pass '#' to the query string like ?page.aspx?someParam=1234#5.

回答1:

Please use Server.UrlEncode on your querystring that will parse the '#' for you

回答2:

Try using %23. This is the url encoded value for #.

回答3:

URL-encode the sharp character: %23.

回答4:

try using escape(url parameter value) method in url instead of only parameter value

回答5:

The best way to pass #, & and other special characters without causing problems in asp.net query string is to use Server.UrlEncode()
See the following example.

  private void btnSubmit_Click(object sender, System.EventArgs e)
  {
     Response.Redirect("page.Aspx?"+"someParam="+Server.UrlEncode("1234#5")); 
  } 

or use %23 replacing # but I think the more suitable way is using Server.UrlEncode() so you can use other special characters without any problem.
