Acess file from isolated storage using its full path as URI

I want to use the file in isolated storage using its full path(like URI), I know there is sandboxed api to access isolated storage. But i have to load the images using their paths.

So is it possible ?

I got it like this:

 public string GetAbsolutePathOfFile(string filePath)
    {
        using (var storage = IsolatedStorageFile.GetUserStoreForApplication())
        {
            using (var isfs = storage.OpenFile(filePath, FileMode.Open, FileAccess.ReadWrite,
                    FileShare.ReadWrite))
            {
                return isfs.Name; // this return the absolute path.
            }
        }
    }
