C#中struct和class的区别

struct和class都能抽象一个物体,他们有什么区别呢?

最大的一个区别 

class是引用类型 

struct是值类型

比如 

 

struct S_Student
{
    public int Number;
    public string Name;
}
class C_Student
{
    public int Number;
    public string Name;
}

            S_Student ss1 = new S_Student() { Number = 1 };
            S_Student ss2 = ss1;
            ss2.Number = 2;
            Response.Write(ss1.Number);

            Response.Write("<br />");

            C_Student cs1 = new C_Student() { Number = 1 };
            C_Student cs2 = cs1;
            cs2.Number = 2;
            Response.Write(cs1.Number);

结果是 1换行2
