Delete a file with specific name and dynamic file extension

How can I search an existing file with dynamic file extension and delete it via Regex?

var reg = new Regex(@"\.jpg|\.jpeg|\.png|\.gif|\.bmp");

I can provide file name but I don't know file extension exactly.

Ex: string fileName = "img01";. I wanna delete these images: img01.jpg, img01.jpeg, img01.png, img01.gif, img01.bmp.

Can you give me a sample to do this?

p/s: I don't want to get all files with specific extension in folder and use a loop to delete it.

You can do this using LINQ and TPL

var reg = new Regex(@"(\.jpg|\.jpeg|\.png|\.gif|\.bmp)$");

Directory.EnumerateFiles(@"C:\temp")
         .Where(file => reg.Match(file).Success).AsParallel()
         .ForAll(File.Delete)

Or just LINQ

var reg = new Regex(@"(\.jpg|\.jpeg|\.png|\.gif|\.bmp)$");

Directory.EnumerateFiles(@"C:\temp")
         .Where(file => reg.Match(file).Success).ToList()
         .ForEach(File.Delete)
