Question

I would like to do a command-line application that will delete files from a specific directory using C# to code it, but I need a library that does it.

Answer 1

System.IO.File.Delete namespace you can see as below

Array.ForEach(Directory.GetFiles(@"c:\MyDir\"),
              delegate(string path) { File.Delete(path); });

or

using System.IO;

string[] filePaths = Directory.GetFiles(@"c:\dirname\");
foreach (string filePath in filePaths)
  File.Delete(filePath)
