.NET 4: IsNullOrEmpty vs IsNullOrWhiteSpace

You might be familiar with the following lines of code and may have used it often in your code when validating string values for null, empty or whitespace:

return String.IsNullOrEmpty(value) || value.Trim().Length == 0;

Now, .NET framework 4.0 provides a new API, IsNullOrWhiteSpace which does the same in a much neater way

return String.IsNullOrWhiteSpace(value);

It may not look like a big change, but makes code much more readable, especially if you have multiple string values to check in one if statement.
