确定打印状态c＃

Question

我想在用户单击“打印”后显示消息框，我已经尝试了以下代码，但是没有出现该消息框。

void printToolStripMenuItem_Click(object sender, EventArgs e)
         {
             PrintFile(sender, e);
         }

void PrintFile(object sender, EventArgs e)
         {
             PrintDialog printDialog = new PrintDialog();

             printDocument1.DefaultPageSettings.Landscape = true;
             printDialog.Document = printDocument1;
             printDialog.UseEXDialog = true;

             if (DialogResult.OK == printDialog.ShowDialog())
             {
                 printDocument1.DocumentName = "Document Page Print";
                 printDocument1.Print();

                 MessageBox.Show("Printed", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
             }
         }

用户单击下图所示的打印按钮后，我想显示该消息框：
