Question

I would like to compare two DataTables. All I need to know is are the contents different yes or no. Can any one recommend a quick way to compare them?

I would like to know if the contents (data) are diffrent

Answer 1

Assuming the tables have the same structure (column names and data types)

static bool AreTablesEqual(DataTable t1, DataTable t2)
{
    // If the number of rows is different, no need to compare the data
    if (t1.Rows.Count != t2.Rows.Count)
        return false;

    for (int i = 0; i < t1.Rows.Count; i++)
    {
        foreach(DataColumn col in t1.Columns)
        {
            if (!Equals(t1.Rows[i][col.ColumnName], t2.Rows[i][col.ColumnName]))
                return false;
        }
    }
    return true;
}
