int Myint = 927;
const int MyWInt = 112;
Console.WriteLine("变量Myint={0}", Myint);
Console.WriteLine("变量MyWInt={0}", MyWInt);
Myint = 1039;
Console.WriteLine("变量Myint={0}", Myint);

运行结果如下：
变量Myint=927
变量MyWInt=112
变量Myint=1039

int Myint = 927;
const int MyWInt = 1122;
Myint = 1133;
Console.WriteLine("Myint初始化的值是：{0}",Myint);
Console.WriteLine("重新赋值后Myint的值是：{0}",Myint);
Console.WriteLine("MyWInt初始化的值是：",MyWInt);

Myint初始化的值是：1133
重新赋值后Myint的值是：1133
MyWInt初始化的值是：1122
