推荐答案

试试这个。希望这是你想要的。 Try this. Hope this what you want. if (FileUpload1.HasFile) { string directoryPath = "~/Mail_Attachments/" + txtSubject.Text; string filePath = directoryPath + "/" + FileUpload1.FileName; if (!Directory.Exists(MapPath(directoryPath))) System.IO.Directory.CreateDirectory(MapPath(directoryPath )); FileUpload1.SaveAs(MapPathfilePath )); temp = filePath ; }

你可以试试这个代码.. Can u try this code.. string directoryPath = Server.MapPath(string.Format("~/Mail_Attachments/"+ txtSubject.Text)); if (!Directory.Exists(directoryPath)) { Directory.CreateDirectory(directoryPath); FileUpload1.SaveAs(MapPath("~/Mail_Attachments/" + txtSubject.Text + FileUpload1.FileName)); }
