如何在WinForms中发送图片到邮件正文

我有一个c# Winforms应用程序，我正在Visual Studio 2010中工作，有问题的页面是一个错误报告表单-我有所有的详细信息设置，电子邮件发送良好等。我的问题是在正文中附加一个截图到电子邮件，我已经设置了代码，允许用户找到并选择他们所采取的截图并附加到表单，但在正文本身，它只是给了我一个文本"System.Windows.Forms。如果我尝试。image.

我已经通过谷歌和这里看了一下，但只能找到与嵌入图像或附加它有关的主题(因此需要在特定文件夹/图像等中输入)，而我的用户将从不同的地方附加他们自己的图像和名称。有没有办法让图像被捡起来，而不必硬编码的位置和名称，我的用户将不得不遵循每次?

    private void btnBugEmail_Click(object sender, EventArgs e)
{
    Cursor.Current = Cursors.WaitCursor;
    try
    {
        SmtpClient client = new SmtpClient("details here");
        MailMessage message = new MailMessage();
        message.From = new MailAddress("email here");
        string mailBox = txtBugAdd.Text.Trim();
        message.To.Add(mailBox);
        string mailFrom = txtEmailFromBug.Text.Trim();
        message.CC.Add(mailFrom);
        string mailCC = txtMailCCBug.Text.Trim();
        message.Bcc.Add(mailCC);
        message.IsBodyHtml = true;
        message.Body = "Bug Report - please see below: " +
            "'n" + "<br>" + "<b>" + "1. What were you doing at the time of the error?" + "</b>" +
                "'n" + "<br>" + rtbTimeOfError.Text +
                "'n" + "<br>" + "<b>" + "2. Are you able to repeat the steps and achieve the same error?" + "</b>" +
                "'n" + "<br>" + rtbCanRepeat.Text +
                "'n" + "<br>" + "<b>" + "3. Does this problem happen again if you change any of the details you have entered?" + "</b>" +
                "'n" + "<br>" + rtbChangeDetails.Text;
        message.Subject = "Bug Report";
        var image = pboxBugImage.Image;
        using(var ms = new MemoryStream()) 
        {
          image.Save(ms, ImageFormat.Jpeg);            
          message.Attachments.Add(new Attachment(ms, "Screenshot.jpg"));    
          client.Credentials = new System.Net.NetworkCredential("credentials here");
          client.Port = System.Convert.ToInt32(25);
          client.Send(message);
        }
        new Endpage().Show();
        this.Close();
    }
    catch
    {
        MessageBox.Show("my comment here");
    }
