.NET Framework Class Library
DataTable..::.GetErrors Method

Gets an array of DataRow objects that contain errors.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)
Syntax

Visual Basic (Declaration)
Public Function GetErrors As DataRow()
Visual Basic (Usage)
Dim instance As DataTable
Dim returnValue As DataRow()

returnValue = instance.GetErrors()
C#
public DataRow[] GetErrors()
Visual C++
public:
array<DataRow^>^ GetErrors()
JScript
public function GetErrors() : DataRow[]

Return Value

Type: array<System.Data..::.DataRow>[]()[]
An array of DataRow objects that have errors.
Remarks

Invoke GetErrors after invoking the DataSet class's GetChanges method. Also, be sure you do not invoke AcceptChanges on the DataTable until after you have resolved all errors, and have re-submitted the DataSet for updating.

Examples

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

Visual Basic
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
C#
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();
            }
        }
    }
}
