Most advisable way of checking empty strings in C# [closed]
Do not compare strings to String.Empty
or ""
to check for empty strings.
Instead, compare by using String.Length == 0
The difference between string.Empty
and ""
is very small. String.Empty
will not create any object while ""
will create a new object in the memory for the checking. Hence string.empty is better in memory management.
But the comparison with string.Length == 0
will be even faster and the better way to check for the empty string.
I think the best way is if(string.IsNullOrEmpty(a))
because it's faster and safer than the other methods.
