c# - How to escape url encoding? -

I am creating a link that creates URL parameters that include links to URL parameters. The problem is that my Is there a link like this

  http: //mydomain/_layouts/test/MyLinksEdit.aspx? Auto = true & source = http: // vtss-sp2010hh: 8088 / AdminReports / helloworld.aspx? Pdfid = 193 and url = http: // vtss-sp2010hh: 8088 / AdminReports / helloworld.aspx? Pdfid = 193% 26pdfname = 5.6% 20Upgrade & title = 5.6 upgrade   
 < Code> auto  is not read or is  
  
  url  bookmark is linked  
  The title is   source  where you have to go after adding or canceling  
  url  code> is the name of the bookmark  
 The values ​​of  url  and  titles  are entered in two fields, then cancel the user  saved  or  T  will need to click on. The problem occurs when the bookmark enters the values ​​in the page field, it will decode them. Then if you try to save, it will not let you save because there is a place in the  pdfname  value in the  url  value. If there is no need for a blank space, then basically, I want that after entering the area, it will still be % 20  rather than a place.  
 There is no problem with  source ,  auto , or  title , just  url . ..  
 Is there a way to solve this? Maybe I like a special escape character like % 20 ?  
  Can use for note: I can not modify bookmark page.   
 I am using c # / asp.net to create a link and go to it.  
 Thanks   
 
 
 Since the .NET Framework 4.5 you have  WebUtility.UrlEncode < / Code>.  
 It resides in  System.dll , so it does not need any additional reference.  
 This avoids the characters properly for the URL, unlike the  Uri.EscapeUriString     
  Uri.EscapeDataString , therefore it can be used for POST requests  
  System.Net.WebUtility.UrlEncode (urltext)   
 Another option  
  System.Uri.EscapeDataString ()
