I needed to do this too  found this question from years ago but question title and text don t quite match up  and using Uri EscapeDataString or UrlEncode  don t use that one please   doesn t usually make sense unless we are talking about passing URLs as parameters to other URLs     For example  passing a callback URL when doing open ID authentication  Azure AD  etc    Hoping this is more pragmatic answer to the question  I want to make a string into a URL using C   there must be something in the  NET framework that should help  right   Yes - two functions are helpful for making URL strings in C    String Format for formatting the URL Uri EscapeDataString for escaping any parameters in the URL   This code  String Format  https   site app  q  0  amp redirectUrl  1       Uri EscapeDataString  search for cats       Uri EscapeDataString  https   mysite myapp  state from idp      produces this result  https   site app  q search 20for 20cats amp redirectUrl https 3A 2F 2Fmysite 2Fmyapp  Which can be safely copied and pasted into a browser s address bar  or the src attribute of a HTML A tag  or used with curl  or encoded into a QR code  etc

As commented on the approved story  the HttpServerUtility UrlEncode method replaces spaces with   instead of  20  Use one of these two methods instead  Uri EscapeUriString   or Uri EscapeDataString   Sample code  HttpUtility UrlEncode  quot https   mywebsite com api get me this file jpg quot     Output   quot https 3a 2f 2fmywebsite com 2fapi 2fget me this file jpg quot   Uri EscapeUriString  quot https   mywebsite com api get me this file jpg quot      Output   quot https   mywebsite com api get 20me 20this 20file jpg quot  Uri EscapeDataString  quot https   mywebsite com api get me this file jpg quot      Output   quot https 3A 2F 2Fmywebsite com 2Fapi 2Fget 20me 20this 20file jpg quot     When your url has a query string  Uri EscapeUriString  quot https   mywebsite com api get id 123 amp name get me this file jpg quot      Output   quot https   mywebsite com api get id 123 amp name get 20me 20this 20file jpg quot  Uri EscapeDataString  quot https   mywebsite com api get id 123 amp name get me this file jpg quot          Output   quot https 3A 2F 2Fmywebsite com 2Fapi 2Fget 3Fid 3D123 26name 3Dget 20me 20this 20file jpg quot
