I'm having trouble finding the correct way to URL encode a string in C#. What I want is to encode the string some string to some%20code. Using HttpUtility.URLEncode(); method encode is to some+string.

So what is the problem? you should use HttpUtility.URLEncode – eyossi May 28 '12 at 12:11

1So, is there something wrong with `string.Replace("+", "%20")`? – harold May 28 '12 at 12:14

HttpUtility.UrlEncode does the right thing here.
Encodes a URL string. The UrlEncode method can be used to encode the entire URL, including query-string values.
When it comes to spaces on the URL, a + or %20 are both correct.

The problem was that I was sending a HTTP request to get the web page, where '+' was not valid. Eg. Sending a query with 'some+string' would search for 'some+string', not 'some string'. – Gregor Menih May 28 '12 at 14:43

What is the minimum required .NET version for HttpUtility.UrlEncode() (not necessarily what is listed in the MSDN page)? – Peter Mortensen May 25 '15 at 19:42

If you want spaces encoded as %20 instead of +, you have to do the encoding yourself.
In URL encoding a + means space. You can also use %20, just as you can use the character code variant for any character, but the built in encoding uses the shorter variant.
