Examples

The following example uses the HasErrors property to determine whether a DataSet object contains errors. If so, the errors for each DataRow in each DataTable are printed.

private void CheckForErrors()
{
    if(!DataSet1.HasErrors)
    {
        DataSet1.Merge(DataSet2);
    }
    else
    {
        PrintRowErrs(DataSet1);
    }
}

private void PrintRowErrs(DataSet dataSet)
{
    foreach(DataTable table in dataSet.Tables)
    {
        foreach(DataRow row in table.Rows)
        {
            if(row.HasErrors)
            {
                Console.WriteLine(row.RowError);
            }
        }
    }
}

Private Sub CheckForErrors()
    If Not DataSet1.HasErrors Then
        DataSet1.Merge(DataSet2)
    Else
       PrintRowErrs(DataSet1)
    End If
End Sub
 
Private Sub PrintRowErrs(ByVal dataSet As DataSet)
    Dim row As DataRow
    Dim table As DataTable
    For Each table In  dataSet.Tables
       For Each row In table.Rows
          If row.HasErrors Then
             Console.WriteLine(row.RowError)
          End If
       Next
    Next
End Sub

Remarks

Each DataTable in a DataSet also has a HasErrors property. Use the HasErrors property of the DataSet first, to determine if any table has errors, before checking individual DataTable objects. If a DataTable has errors, the GetErrors method returns an array of DataRow objects containing the errors.
