如何在上傳時重命名文件

Question

我正在上傳file.so我想更改我的文件名。

string createfolder = "E:/tmp/jobres/" + uId; 
System.IO.Directory.CreateDirectory(createfolder); 
string newfilename = txtname.Text + "Resume" + fileExtension; 
AsyncFileUpload1.SaveAs(Path.Combine(createfolder,newfilename)); 

這個時間文件是在不同的格式，那麼它不能取代。

Answer 1

string createfolder = "E:/tmp/jobres/" + uId; 

System.IO.Directory.CreateDirectory(createfolder); 

//AsyncFileUpload1.SaveAs(Path.Combine(createfolder,"Give Something Here whatever is changing at all time like time value"+AsyncFileUpload1.PostedFile.FileName)); 

AsyncFileUpload1.SaveAs(Path.Combine(createfolder,"DateTime.Now"+AsyncFileUpload1.PostedFile.FileName));
