Change file name of image path in C#
This following code snippet changes the filename and leaves the path and the extenstion unchanged:
string path = @"photo\myFolder\image.jpg";string newFileName = @"image-resize";string dir = Path.GetDirectoryName(path);string ext = Path.GetExtension(path);path = Path.Combine(dir, newFileName + ext); // @"photo\myFolder\image-resize.jpg"
You can use Path.GetFileNameWithoutExtension method.
Returns the file name of the specified path string without the extension.
string path = @"photo\myFolder\image.jpg";string file = Path.GetFileNameWithoutExtension(path);string NewPath = path.Replace(file, file + "-resize");Console.WriteLine(NewPath); //photo\myFolder\image-resize.jpgHere is a DEMO.
