Remove all whitespace from C# string with regex

Question

I am building a string of last names separated by hyphens. Sometimes a whitespace gets caught in there. I need to remove all whitespace from end result. Sample string to work on: Anderson -Reed-Smith It needs to end up as (no space after Anderson): Anderson-Reed-Smith The last name string is in a string variable, LastName. I am using a regular expression: ``` Regex.Replace(LastName, @"[\s+]", ""); ``` The result of this is: Anderson -Reed-Smith. I also tried: ``` Regex.Replace(LastName, @"\s+", ""); ``` and ``` Regex.Replace(LastName, @"\s", ""); ``` What am I doing wrong?

Accepted Answer

Instead of a `RegEx` use `Replace` for something that simple:

```
LastName = LastName.Replace(" ", String.Empty);
```
