如何使用c＃创建文​​件夹并在其中保存文件

Question

我创建新文件夹，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已创建的文件夹中？

Answer 1

由于您在保存时使用MapPath，因此您的目录可能会在错误的位置创建。在创建目录时，您应该使用MapPath：

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));
