Method 1

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

Method 2

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

Method 3

URL-encode the sharp character: %23.

Method 4

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

Method 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.
