C# Empty Statement(;)

In this chapter you will learn:
  • What is Empty Statement in C#?
  • How to use Empty Statement in C#?
  • What is the benefit of using Empty Statement in C#?

An empty statement is used when you no need to perform an operation where a statement is required. It simply transfers control to the end point of the statement. It is also very useful with a while loop with the blank body and label statements.

Example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace empty_statements
{
    class Program
    {
        public bool print()
        {
            Console.WriteLine("Steven Clark");
            return true;
        }
        static void Main(string[] args)
        {
            int i = 0;
            Program p = new Program();
            while (p.print())
            {
                ; //Empty Statement
            }
            Console.WriteLine("i = {0}", i);
            Console.ReadLine();
        }
    }
}

  Note: It processes infinite loop so terminating the program press ctrl+c.
