public:
 cli::array <System::Data::DataRow ^> ^ GetErrors();

public System.Data.DataRow[] GetErrors();

member this.GetErrors : unit -> System.Data.DataRow[]

Public Function GetErrors () As DataRow()

Returns

An array of DataRow objects that have errors.

Examples

The following example uses the GetErrors method to return an array of DataRow objects that have errors.

private void PrintAllErrs(DataSet dataSet)
{
 DataRow[] rowsInError;

 foreach(DataTable table in dataSet.Tables)
 {
 // Test if the table has errors. If not, skip it.
 if(table.HasErrors)
 {
 // Get an array of all rows with errors.
 rowsInError = table.GetErrors();
 // Print the error of each column in each row.
 for(int i = 0; i < rowsInError.Length; i++)
 {
 foreach(DataColumn column in table.Columns)
 {
 Console.WriteLine(column.ColumnName + " " +
 rowsInError[i].GetColumnError(column));
 }
 // Clear the row errors
 rowsInError[i].ClearErrors();
 }
 }
 }
}

Private Sub PrintAllErrs(ByVal dataSet As DataSet)
 Dim rowsInError() As DataRow
 Dim table As DataTable 
 Dim i As Integer
 Dim column As DataColumn
 For Each table In dataSet.Tables
 ' Test if the table has errors. If not, skip it.
 If table.HasErrors Then
 ' Get an array of all rows with errors.
 rowsInError = table.GetErrors()
 ' Print the error of each column in each row.
 For i = 0 To rowsInError.GetUpperBound(0)
 For Each column In table.Columns
 Console.WriteLine(column.ColumnName, _
 rowsInError(i).GetColumnError(column))
 Next
 ' Clear the row errors
 rowsInError(i).ClearErrors
 Next i
 End If
 Next
End Sub

Remarks

Returns the list of DataRow objects that have RowError set. For example, errors can occur when calling Update with ContinueUpdateOnError set to true. Do not invoke AcceptChanges on the DataTable until you resolve all errors and resubmit the DataSet for updating.
