C# - Simplest way to remove first occurrence of a substring from another string

Question

I need to remove the first (and ONLY the first) occurrence of a string from another string.

Here is an example replacing the string "\\Iteration". This:

 ProjectName\\Iteration\\Release1\\Iteration1 

would become this:

 ProjectName\\Release1\\Iteration1 

Here some code that does this:

const string removeString = "\\Iteration"; int index = sourceString.IndexOf(removeString); int length = removeString.Length; String startOfString = sourceString.Substring(0, index); String endOfString = sourceString.Substring(index + length); String cleanPath = startOfString + endOfString; 

That seems like a lot of code.

So my question is this: Is there a cleaner/more readable/more concise way to do this?

Answer 1

int index = sourceString.IndexOf(removeString); string cleanPath = (index < 0)     ? sourceString     : sourceString.Remove(index, removeString.Length);
