. C #-struct type, reference type

struct type: value type, and class is reference type

Structure definition:

• Structs are defined in much the same way as classes, but structs are value types, and classes are reference types;

• object is a reference type, when assigning an object to a variable, it assigns a pointer to the object that the pointer points to, changes one of the values, and the value changes;

Using system;using system.collections.generic;using system.linq;using system.text;using  system.threading.tasks;namespace consoleapplication1{    class program     {        class MyClass         {            public  int val;        }         struct MyStruct        {             public int val;         }        static void main (String [] args)         {             myclass objeCta = new myclass ();             myclass objectb = objecta;             objectA.val = 100;             Objectb.val = 200;            mystruct  structa = new mystruct ();             MyStruct StructB = StructA;             StructA.val = 100;             StructB.val = 200;             console.writeline ("object a = {0}", Objecta.val);             consoLe. WriteLine ("object b = {0}", Objectb.val);             console.writeline ("struct a = {0}", Structa.val);             console.writeline ("struct b = {0}",  Structb.val);             console.readline ();         }    }}

Results:

Object A =200
Object B =200
Struct A =100
Struct B =200
