Why do you think it should be done only with space characters? I bet what you need is not what you are asking about.

In general case, you just use string.Replace:

http://msdn.microsoft.com/en-us/library/fk49wtc1(v=vs.110).aspx[^].

But I am nearly sure that what you really need is not what you are asking for. Most likely, you need to encode not only spaces, but everything which is not allowed in URL. Please see:

There are loads of ways, but the simplest might be:

string output = input.Replace(" ", "%20");
