String.IsNullOrEmpty (.NET 2.0)
How many times have you written the following string validation code:
if (_name == null || _name.Length == 0)
{
// ...
}
With .NET 2.0, you can use the static ("Shared" in Visual Basic.NET) utility method String.IsNullOrEmpty to do the same thing:
if (string.IsNullOrEmpty(_name))
{
// ...
}
