What I did was write a IsNullOrBlank in a Helper Class.
the key is that you will want to test length because that is quicker than testing the string itself. is string == ""; sting.length == 0
Also want to test null before lenght. The idea is that if one is true then the if stops. If the first test is for lenght on a sting that is null you will get an error. So the order of the test is important because if buffer == null the other 'or' part of the
if will not execute.
public class StringHelper
{
public static bool IsNullOrBlank(string testBuffer)
{
if(testBuffer == null || testBuffer.Length == 0)
return true;
else
return false;
}
}
if(!StringHelper.IsNullOrBlank(buffer))
buffer not null
else
buffer is null
if(StringHelper.IsNullOrBlank(buffer))
buffer is null
else
buffer is not null
