引用类型参数与引用参数的区别

namespace ConsoleApp

{

class Class1

{

static void Main(string[] args)

{

Class1 c1 = new Class1(444);

c1.M2(c1);

System.Console.WriteLine(c1.MyProperty);

c1.M1(out c1);

System.Console.WriteLine(c1.MyProperty);

System.Console.ReadKey();

}

public int MyProperty { get; set; }

public void M1(out Class1 c1)

{

c1 = new Class1(111);

}

public void M2(Class1 c1)

{

c1 = new Class1(222);

}

public Class1(int i)

{

MyProperty = i;

}

}

}

output:

444
