如何创建文件夹并使用c保存文件＃

Question

我创建新的文件夹，但如何保存文件，请帮助我。

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

但如何将我的文件存储在创建的文件夹？

Answer 1

由于您在保存时使用MapPath，您的目录可能会在错误的位置创建。

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));
