In C#, what is the best way to test if a dataset is empty?

Question

I know you can look at the row.count or tables.count, but are there other ways to tell if a dataset is empty?

Answer 1

#region Extension methods

public static class ExtensionMethods
{
    public static bool IsEmpty(this DataSet dataSet)
    {
        return dataSet == null || dataSet.Tables.Count == 0 || !dataSet.Tables.Cast().Any(i => i.Rows.Count > 0);
    }
}

#endregion
