DataTable.GetErrors 方法

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

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

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

Public Function GetErrors () As DataRow()

具有錯誤之 DataRow 物件的陣列。

下列範例會 GetErrors 使用 方法傳回有錯誤的 物件陣列 DataRow 。

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

傳回已RowError設定的物件DataRow清單。 例如，呼叫 Update 時，可能會發生錯誤，並將 ContinueUpdateOnError 設定為 true。 在您解決所有錯誤並重新提交DataSet以進行更新之前，請勿在 上DataTable叫AcceptChanges用 。
