Static Classes and Members

A static member of the class is a property, procedure, or field that is shared by all instances of a class.

To define a static member:

static class SampleClass  
 {  
     public static string SampleString = "Sample String";  
 }

 
Console.WriteLine(SampleClass.SampleString);   

Static classes in C# have static members only and cannot be instantiated. Static members also cannot access non-static properties, fields or methods
