Change File Extension Using C#

Question

I have many file types: pdf, tiff, jpeg, bmp. etc. My question is how can I change file extension? I tried this: ``` my file= c:/my documents/my images/cars/a.jpg; string extension = Path.GetExtension(myffile); myfile.replace(extension,".Jpeg"); ``` No matter what type of file it is, the format I specify must be with the file name. But it does not work. I get file path from browser like `c:\..\..\a.jpg`, and the file format is `a.jpeg`. So, when I try to delete it, it gives me an error: `Cannot find the file on specified path'`. So, I am thinking it has something to do with the file extension that does not match. So, I am trying to convert `.jpg` to `.jpeg` and delete the file then.

Accepted Answer

There is: `Path.ChangeExtension` method. E.g.:

```
var result = Path.ChangeExtension(myffile, ".jpg");
```

In the case if you also want to physically change the extension, you could use `File.Move` method:

```
File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));
```
