Replacing Space by Empty Character in c#

Question

how to replace any charachter with nothing. for example

1 : string inputString = "This Is Stack OverFlow";
2 : string outputString = inputString.Replace(' ', '');

expected output = "ThisIsStackOverFlow";

I tried line 2 but it says empty Character String in Replace methods second argument. Can any body tell me whats wrong with my Replace Method and why it does not take blank like we normally use in string (for ex : "")?

Answer 1

Because you are using the Replace(char, char) overload instead of Replace(string, string) ('' is not a valid character). Just use this:

string ouputString = inputString.Replace(" ", "");

Answer 2

You can simply use the '\0' character

Console.WriteLine("String w i t h. Holes !".Replace(' ','\0'));
