Static Class Or Utility Class C# with Example

 	using System;

	namespace CSharpClass
	{
		// Static classes can only contain static members!
		static class TimeUtilClass
		{
			public static void PrintTime()
			{ 
				Console.WriteLine(DateTime.Now.ToShortTimeString()); 
			}
			
			public static void PrintDate()
			{ 
				Console.WriteLine(DateTime.Today.ToShortDateString());
				}
		}
				
		class UsingStudent
		{
			static void Main(string[] args)
			{
				Console.Write("Today's Date: " );
				TimeUtilClass.PrintDate();
				
				Console.Write("Current Time: " );
				TimeUtilClass.PrintTime();

				// Compiler error! Can't create static classes!
				// TimeUtilClass u = new TimeUtilClass ();
			}
		}
