範例

Public Sub DisplaySqlCeErrors(ByVal errorCollection As SqlCeErrorCollection)

    Dim err As SqlCeError
    Dim bld As New StringBuilder()

    For Each err In errorCollection
        bld.Append((ControlChars.Cr & " Error Code: " & err.HResult.ToString("X")))
        bld.Append((ControlChars.Cr & " Message   : " & err.Message))
        bld.Append((ControlChars.Cr & " Minor Err.: " & err.NativeError))
        bld.Append((ControlChars.Cr & " Source    : " & err.Source))

        Dim numPar As Integer
        For Each numPar In err.NumericErrorParameters
            If 0 <> numPar Then
                bld.Append((ControlChars.Cr & " Num. Par. : " & numPar))
            End If
        Next numPar

        Dim errPar As String
        For Each errPar In err.ErrorParameters
            If [String].Empty <> errPar Then
                bld.Append((ControlChars.Cr & " Err. Par. : " & errPar))
            End If
        Next errPar

        MessageBox.Show(bld.ToString())
        bld.Remove(0, bld.Length)
    Next err

End Sub 'DisplaySqlCeErrors
public void DisplaySqlCeErrors(SqlCeErrorCollection errorCollection ) {
    StringBuilder bld = new StringBuilder();

    foreach (SqlCeError err in errorCollection) {

        bld.Append("\n Message   : " + err.Message);
        bld.Append("\n Minor Err.: " + err.NativeError);
        bld.Append("\n Source    : " + err.Source);

        foreach (int numPar in err.NumericErrorParameters) {
            if (0 != numPar) bld.Append("\n Num. Par. : " + numPar);
        }

        foreach (string errPar in err.ErrorParameters) {
            if (String.Empty != errPar) bld.Append("\n Err. Par. : " + errPar);
        }

        MessageBox.Show(bld.ToString());
        bld.Remove(0, bld.Length);
