推荐答案

尝试 Server.MapPath（）

Try Server.MapPath()

string fileName =uId + "ContactList.pdf";
string strPath = Server.MapPath(@"TempFiles/"+fileName);

参考： HttpServerUtility.MapPath Method（String）（System.Web） [ ^ ]

Hope ，它有帮助：）

Hope, it helps :)

试试这个

Try This

public string CommonFileSave(HttpPostedFileBase postedFile, string filePath)
       {
           string resultResponse = "sccuess";

           if (!Directory.Exists(filePath))
           {
               Directory.CreateDirectory(filePath);
               postedFile.SaveAs(filePath + postedFile.FileName);
           }
           else
           {
               filePath = filePath + postedFile.FileName;
               if (!System.IO.File.Exists(filePath))
               {
                   postedFile.SaveAs(filePath);
               }
           }
           return resultResponse;
       }
