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

I have created a small static util class just for that purpose

Below code should read like an English sentence.

    public static bool DataSetIsEmpty(DataSet ds)
    {
        return !DataTableExists(ds) && !DataRowExists(ds.Tables[0].Rows);
    }

    public static bool DataTableExists(DataSet ds)
    {
        return ds.Tables != null && ds.Tables.Count > 0;
    }

    public static bool DataRowExists(DataRowCollection rows)
    {
        return rows != null && rows.Count > 0;
    }

I would just put something like below code and be done with it. Writing a readable code does count.

        if (DataAccessUtil.DataSetIsEmpty(ds)) {
            return null;
        }
