DataTable.GetErrors Method

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

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

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

Public Function GetErrors () As DataRow()

An array of DataRow objects that have errors.

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

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.
