Check if no datarows returned

Question

I have this which check for datarows which match an expression:

DataRow[] foundRows = this.callsTable.Select(searchExpression);

How do i check if it returns some datarows, so basically if it returns none don't do what's in the if function?

I have tried:

if (foundRows != null) { }

You can use the Length property of array to check if you get any rows

if (foundRows.Length == 0)
