How to change file name in c#?

Question

I am having trouble with the file name returns from the file dialog box. I need to change only the file name but not its path.
I want something like this...

string name_to_change="abc";
string filenameAtClient = this.saveFileDialog.FileName;
filenameAtClient=name_to_change;

You mean to change the name of the file in file system or in your `filenameAtClient` variable? — Sriram Sakthivel, Nov 07 '14 at 07:31

Maybe you have to check MSDN, for example:

string name_to_change = "abc";
string filenameAtClient = this.saveFileDialog.FileName;
filenameAtClient = filenameAtClient.Replace(Path.GetFileName(filenameAtClient), name_to_change);

OR without the file extension:

string name_to_change = "abc";
string filenameAtClient = this.saveFileDialog.FileName;
filenameAtClient = filenameAtClient.Replace(Path.GetFileNameWithoutExtension(filenameAtClient), name_to_change);

thanks for your response but it is not returning the extension – Manish Jain Nov 07 '14 at 07:46
I guess I'm not understanding what you're trying to achieve. Do you want to change the filename with extension, the filename without extension or just the extension? – SolarX Nov 07 '14 at 07:50
you were right .. I have done it. Thanks! – Manish Jain Nov 07 '14 at 08:21
