before you dispose, do you have to close anything?

can  you place a try/catch around code...

string str_Error;      
try{
upfile.SaveAs(Server.MapPath(@"csv\temp.csv"));
//close upfile here...
}
catch (Exception ex)
{
     str_Err = ex.StackTrace.ToString();   //gives BETTER ERROR message...
}
finally
{
      upfile.Dispose();
}

However, it works on localhost. When I upload the web application to remote machine, it happens that error after upload the file first time.

It means it is ok to upload in the first time.
It throws such exception in 2nd time.

It's most likely because the filename is the same...if the file is not there, does it work?

upfile.SaveAs(Server.MapPath(@"csv\temp.csv"));
System.IO.StreamReader strFile = new System.IO.StreamReader(Server.MapPath(@"csv\temp.csv"));

As I just need to read the data from the csv file and then insert to remote database.

Actually, there is no need to save the file.

However, how to handle this code?
System.IO.StreamReader(Server.MapPath(@"csv\temp.csv"));

Why not create a stream from the uploaded file without saving it to the disk. Try this
strFile=upfile.postedfile.inputstream()
