最近碰到一個發送郵件附件的問題，隨便幾下來，方便以後學習。
string[] files = System.IO.Directory.GetFiles(@"~/UploadData" + "/" + DateTime.Now.ToString("yyyyMM")); //獲取文件路徑
foreach (string file in files) //循環文件夾裏面文件個個數
{
//string extension = System.IO.Path.GetExtension(file); 文件擴展名
var attachmentMail = new System.Net.Mail.Attachment(@file);
message.Attachments.Add(attachmentMail);
}
smtp.Send(message); //發送郵件
ret.success = true;
ret.message = "发送成功";
CODE:
/// <summary>
