範例

下列範例示範如何覆寫 OnEndLoad 方法，以顯示載入工作流程期間可能發生的錯誤。

protected override void OnEndLoad(bool successful, ICollection errors)
{
    base.OnEndLoad(successful, errors);

    if (!successful && errors != null)
    {
        System.Text.StringBuilder sb = new System.Text.StringBuilder("Errors\r\n");
        foreach (string error in errors)
        {
            sb.Append(error + "\r\n");
        }

        MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

Protected Overrides Sub OnEndLoad(ByVal successful As Boolean, ByVal errors As ICollection)
    MyBase.OnEndLoad(successful, errors)

    If Not successful And errors IsNot Nothing Then
        Dim sb As New System.Text.StringBuilder("Errors\r\n")
        For Each errorMessage As String In errors
            sb.Append(errorMessage + "\r\n")
        Next

        MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
    End If
End Sub
