what is static method in c# code example

Example 1: c# static meaning

In general, static means “associated with the class, not an instance”.
// Search c# static review for more detail

Example 2: static c#

(static) >> means that the method belongs to the Program class 
			and not an 'object' of the Program class.

Example 3: static class can have non static member in c#

Static class can't contain non-static members because by definition it can't be instantiated so there's no possibility to use these members. However, static members in non-static class can be used without having class instance - a bit different scenario,

Example 4: what is using static in c#

// The using static directive designates a type whose static 
// members and nested types you can access without specifying a type name.
using System;
using static System.Math;

public class Circle
{
   public Circle(double radius) 
   {
      Radius = radius;
   }
   public double Radius { get; set; }
   public double Diameter 
   {
      get { return 2 * Radius; }
   }
   public double Circumference 
   {
      get { return 2 * Radius * PI; }
      // otherwise if not using static "get { return 2 * Radius * Math.PI; }"
   }
   public double Area 
   {
      get { return PI * Pow(Radius, 2); }
     // otherwise if not using static "get { return Math.PI * Math.Pow(Radius, 2); }"
   }
}

Example 5: static methods c#

class Program  
{  
    public static void withoutObj()  
    {  
        Console.WriteLine("Hello");  
    }  
     static void Main()  
    {  
        Program. withoutObj();  
        Console.ReadKey();  
    }  
}
