Difference between member variable and local variable in C#

Member variables:

　　Definition: Variables defined in a class are called member variables

　　Scope: Valid in the entire class

　　Classification: Member variables can be divided into instance variables and static variables (plus the keyword static)

class test1
｛
      int   a =   33 ;     // Instance variable, valid in class test1 
      static  int b = 45 ;    // Static variable, valid in the whole program, can be called in other classes           
}

 

local variable:

　　Definition: Variables defined in a method are called local variables

　　Scope: Effective within the currently defined method, the method call is destroyed, and cannot be called in other classes
