DirectoryNotFoundException in C#

If a directory you are trying to find does not exist, then DirectoryNotFoundException occurs.

Here, we are try to find a directory that does not exist using GetDirectories() method.

Example

using System.IO;
using System;
class Program {
   static void Main() {
      Directory.GetDirectories("D:\new\");
   }
}

The above code will generate the following exception since the directory “D:\new” does not exist.

Unhandled Exception:
System.IO.DirectoryNotFoundException: Could not find a part of the path
