先看简图：

C#中的运算符就有这些，简单介绍下C#中的赋值运算符。

 class SimpleAssgningOP    //定义类            {                public int i;            }        class RefTestApp        {            public static void main()            {                SimpleAssgningOP  test1 =new SimpleAssgningOP ();                test1.i=1;                SimpleAssgningOP test2=new SimpleAssgningOP() ;                test2.i=2;                Console.WriteLine ("Before object assignment");                Console .WriteLine ("test1.i={0}",test1.i);                 Console .WriteLine ("test2.i={0}",test2.i);                             test1=test2;                Console .WriteLine ("After object assignment");                Console.WriteLine ("Before object assignment");                 Console .WriteLine ("test1.i={0}",test1.i);                 Console .WriteLine ("test2.i={0}",test2.i);                test1.i=150;                Console .WriteLine ("After change to only test1 member");                     Console .WriteLine ("test1.i={0}",test1.i);                 Console .WriteLine ("test2.i={0}",test2.i);            }        }        }    }

运算结果：

Before object assignment

test1.i=1

test2.i=2

After object assignment

Before object assignment

test1.i=2

test2.i=2

After change to only test1 member

test1.i=150

test2.i=150

注意：虽然只是改变了test1的值，但test2的值也改变了。
