C#中类和结构的区别讲解

class Program
    {
        static void Main(string[] args)
        {
            /*声明类对象 并赋值10*/
            TestClass TC1 = new TestClass();
            TC1.x = 10;
            TC1.y = "10";
            Console.WriteLine("/*声明类对象TC1 并赋值10*/");
            Console.WriteLine("TC1 x={0} y={0}", TC1.x, TC1.y);
            TC1.x = 20;
            TC1.y = "20";
            Console.WriteLine("/*修改类对象 TC1 值为20*/");
            Console.WriteLine("TC1 x={0} y={0}", TC1.x, TC1.y);

            /*执行类传递 并修改传递后的值*/
            Console.WriteLine("/*创建类对象 TC2 指向 TC1,并修改 值为10*/");
            TestClass TC2 = TC1;
            TC2.x = 10;
            TC2.y = "10";
            Console.WriteLine("/*类传输过程中传递的是存储在堆栈中的引用地址 传输中消耗内存小 并没有传送存储在堆中的值 所以原有对象受到影响*/");
            Console.WriteLine("TC1 x={0} y={0}", TC1.x, TC1.y);
            Console.WriteLine("TC2 x={0} y={0}", TC2.x, TC2.y);


            /*声明结构对象*/
            Console.WriteLine("/*声明结构对象TS1 并赋值10*/");
            TestStruct TS1 = new TestStruct();
            TS1.x = 10;
            TS1.y = "10";
            Console.WriteLine("TS1 x={0} y={0}", TS1.x, TS1.y);

            TestStruct TS2 = TS1;
            TS2.x = 10;
            TS2.y = "10";
            Console.WriteLine("/*结构传输过程中 会传递整个对象的副本 传输中消耗内存大 所以修改对原有对象不受影响*/");
            Console.WriteLine("TS1 x={0} y={0}", TS1.x, TS1.y);
            Console.WriteLine("TS2 x={0} y={0}", TS2.x, TS2.y);

            Console.ReadLine();
