Static classes and class members

1. Static classes contain only static members

2. Cannot instantiate

3. Is sealed and cannot be inherited

4. You can have a static constructor that cannot contain an instance constructor

5. Accessing static members directly with class names and members

6. A common use of static classes might be to create a math library that contains a set of mathematical methods

 Public Static class mymath{      publicstaticfloat3.14f;        Public Static BOOL isodd (int  x)      {          return21;      }}

A. Non-static classes can contain static methods, fields, properties, or events

B. Static methods and properties cannot access non-static fields and events

C. A const field is inherently static

 Public classautomobile{Private Static intVal; Private Const intnumberofwheels=4;//const as static field processing       Public Static voidPrint () {Console.WriteLine ("The automobile has {0} wheels.", Numberofwheels); }       Public Static intSize//only static fields are accessible      {          Get         {             returnVal; }          Set{Val=value; }      }}
