Given a file, and we have to delete it using C# program.

Deleting a file

To delete a file in C#, we use File.Delete() method. The delete() method deletes the file from the given path. Where the path defines the name of the file to be deleted. This method may raise an ArgumentException if the path is a zero-length string and an ArgumentNullException if the path is null. If the file to be deleted is in use by another application, it raises an IOException.

File.Delete()

This is a method of "File" class, it is used to delete the given file.

Syntax

void File.Delete(path);

namespace ConsoleApplication1 {
  class Program {
    static void Main() {
      //method to delete file
      File.Delete("123.TXT");
      
      //confirmation message
      Console.WriteLine("File deleted successfully");
    }
  }
}
