如何創建文件夾並使用c保存文件＃

Question

我創建新的文件夾，但如何保存文件，請幫助我。

string createfolder = "E:/tmp/jobres/" + uId;  
System.IO.Directory.CreateDirectory(createfolder); 
AsyncFileUpload1.SaveAs(Server.MapPath("/tmp/jobres/" + AsyncFileUpload1.PostedFile.FileName)); 

但如何將我的文件存儲在創建的文件夾？

Answer 1

由於您在保存時使用MapPath，您的目錄可能會在錯誤的位置創建。

var createfolder = Path.Combine(Server.MapPath("/tmp/jobres/"), uId.ToString());  
System.IO.Directory.CreateDirectory(createfolder); 
AsyncFileUpload1.SaveAs(Path.Combine(createdFolder, AsyncFileUpload1.PostedFile.FileName)); 

Answer 2

string createfolder = "/tmp/jobres/" + uId;       
System.IO.Directory.CreateDirectory(createfolder); 
AsyncFileUpload1.SaveAs(Path.Combine(createfolder,AsyncFileUpload1.PostedFile.FileName));
