How can I rename a file in ASP.NET?

Question

In my project I want to rename the file before it is updating. For example a file in my system like Mycontact.xls. I want to rename it as sasi.xls (it is an excel file). How can I write the code in ASP.NET?

Actually I am using a fileupload control to get the file in and rename the file and upload the renamed file in a folder which is in Solution Explorer.

Answer 1

You can do it with the File.Move method eg:

string oldFileName = "MyOldFile.txt";
string newFileName = "MyNewFile.txt";
File.Move(oldFileName, newFileName);

Answer 2

C# does not provide a file rename function, unfortunately. Anyhow, the idea is to do this:

File.Copy(oldFileName, NewFileName);

File.Delete(oldFileName);

You can also use - File.Move.
