复制代码 代码如下:

class Program

{

//使用out后必须对变量赋值

public void TestOut(out int x, out int y)

{

x = 1;

y = 2;

}

//此时传进来的值分别为x1:10,y1:11,输出之后的x1的值为2

public void TestRef(ref int x, ref int y)

{

//引用剪剪那句话传进来的是猪,出来的可能是头牛(很精辟！)

x = 2;

}

static void Main(string[] args)

{

int x;

int y;

Program P1 = new Program();

P1.TestOut(out x,out y);

Console.WriteLine("x={0},y={1}", x, y);

//在使用之前ref必须对变量赋值

int x1 = 10;

int Y1 = 11;

P1.TestRef(ref x1,ref Y1);

Console.WriteLine("x1={0},y1={1}", x1, Y1);

}

}
