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.
