How to Cast a dropped Outlook Contact Item on a Winform C#?

使用拖放的方法DragDrop

this.textBox.DragDrop += new System.Windows.Forms.DragEventHandler(this.textBox3_DragDrop);
this.textBox.DragEnter += new System.Windows.Forms.DragEventHandler(this.textBox3_DragEnter);

private void textBox_DragEnter(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.Link; //鼠标的样式
}

private void textBox_DragDrop(object sender, DragEventArgs e)
        {
            if (e.Data.GetFormats()[0] == "RenPrivateSourceFolder")
            {
                Microsoft.Office.Interop.Outlook.Application outlook = Marshal.GetActiveObject("Outlook.Application") as Microsoft.Office.Interop.Outlook.Application;
                Microsoft.Office.Interop.Outlook.MailItem contact = outlook.ActiveExplorer().Selection[1] as Microsoft.Office.Interop.Outlook.MailItem;
                if (contact != null)
                {
                    //string title = contact.Subject.Replace(":","_").Replace("//","_").Replace("/","_").Replace("*","_").Replace("?","_").Replace("<","_").Replace(">","_").Replace("|","_").Replace("/"","_");
                    string title = Regex.Replace(contact.Subject, @"[/////:/?/</>/*/|///""]", "_");
                    //文件夹以当天时间命名,如20090421
                    string strDate = DateTime.Now.Date.ToString("yyyyMM");
                    string strHM = DateTime.Now.ToString("yyyyMMddHHmmssfff");
                    //string priPath = @"//qcsap/its8686_send/";

                    string priPath = System.Configuration.ConfigurationSettings.AppSettings["strPath"];
                    if (!Directory.Exists(priPath+strDate))//判断文件夹是否存在
                    {
                        Directory.CreateDirectory(priPath + strDate); //创建新文件夹
                    }

                    contact.SaveAs(priPath+strDate+"//"+strHM+"_"+title + ".msg", Type.Missing);
                    textBox.Text = priPath + strDate + "//" +strHM+"_"+title + ".msg";
                }
                else
                {
                    MessageBox.Show("Not Contact Item");
                }
            }
            else
            {
                MessageBox.Show("Not Outlook Item");
            }
        }
