Question

I have the following C# code to replace .‘s and +‘s with spaces:

string MyString = "this.is.just+an++example--here!are$more characters";
MessageBox.Show(Regex.Replace(MyString, @"[\.\+]", " "));

Sometimes this might result in excess whitespace (as in, between an and example).

How can I also add the following RegEx to my existing RegEx, so there is only a single RegEx call?

Regex.Replace(MyString, @"[ ]{2,}", " ");

This will remove excess whitespace. All other characters should remain untouched.

Any alternate solutions are also welcome!

Answer 1

Maybe you should match multiple characters in the first place. Change the regexp to "[\.\+]+"to match one or more . or + signs. For example, "a...++b" would result in "a b"

MessageBox.Show(Regex.Replace(MyString, @"[\.\+]+", " "));
