我在windows窗体中做了一个获取邮件附件的方法，下面是代码，但是问什么没有成功啊

string path = "";
                        //获取附件
                        foreach (MimeEntity entry in m.Attachments)
                        {
                            string fileName = entry.ContentDisposition_FileName; //获取文件名称
                            path = "E:\\jmail\\WindowsFormsApplication1\\Attch\\" + fileName;
                            if (File.Exists(path))
                            {
                                Random random = new Random();
                                int newfile = random.Next(1, 100000);
                                path = "E:\\jmail\\WindowsFormsApplication1\\Attch\\Attch" + newfile.ToString();
                                Directory.CreateDirectory(path);
                                path += "\\" + fileName;
                            }
                            byte[] data = entry.Data;
                            FileStream pFileStream = null;
                            pFileStream = new FileStream(path, FileMode.Create);
                            pFileStream.Write(data, 0, data.Length);
                            pFileStream.Close();
                        }
