C# .Net How to Encode URL space with %20 instead of +

Question

How to encode query string space with %20 instead of + ? Because System.Web HttpUtility.UrlEncode() gives the space with +.

@MichaelFreidgeim might you be a little more specific than "modern" please - I am running with target framework netcoreapp3.1 and HttpUtility.UrlEncode(somestring) is giving me + instead of %20 — MemeDeveloper, Jan 19 '21 at 20:37

You may want to use Uri.EscapeDataString() Because Uri string will get spaces but will not encode other characters. Example '#' – Robert Koernke Jun 19 '19 at 20:07

Uri.EscapeUriString has been marked as obsolete as of 9/15/2021 since it "can corrupt the Uri string in some cases." As @Robert Koernke said, the new recommended approach by Microsoft is Uri.EscapeDataString() – arrakis90 Apr 04 '22 at 16:35
