正确理解C#中的关键字[2]

//

// MyClass definition

public class MyClass

{

public int Value;

}

//

// Tester methods

public static void TestRef(ref MyClass m)

{

mValue = ;

}

public static void TestNoRef(MyClass m)

{

mValue = ;

}

public static void TestCreateRef(ref MyClass m)

{

m = new MyClass();

mValue = ;

}

public static void TestCreateNoRef(MyClass m)

{

m = new MyClass();

mValue = ;

}

public static void Main()

{

MyClass m = new MyClass();

mValue = ;

TestRef(ref m);

ConsoleWriteLine(mValue);

TestNoRef(m);

ConsoleWriteLine(mValue);

TestCreateRef(ref m);

ConsoleWriteLine(mValue);

TestCreateNoRef(m);

ConsoleWriteLine(mValue);

}

大家能马上给出正确的答案么?如果能那看来你对 ref 的用法了解得还是非常不错的其实如果大家对 C++ 比较熟悉的话把这段代码换成 C++ 的就好理解的多了
