Hi to everybody.,

I have a problem with renaming a file in asp .net. The problem is that

=> I am uploading .pdf format file through a page and assigning the file name through some fields text. And i am storing that file in folder of the project and file name in database.

But while updating the file i will not select the new file, but i want to change the name of that old file in database as well as file which is in the particular folder.

so how i can change the name of the file in folder? I''m getting to change the name in database but not in folder file name.

使用

Yes as per the OriginalGriff wrote, if you want to rename the file then, you have to use Move() method which is static method of File class. This class is available in System.IO namespace... <br />
syntax :<br />
<pre>File.Move(oldFileName, newFileName);</pre><br />
or you can use copy and delete command like....<br />
<pre lang="midl">File.Copy(oldFileName, NewFileName);<br />
<br />
File.Delete(oldFileName);</pre><br />
