C＃中以下代码段的可能值是多少？ [英] What is possible value for the below snippet in C#

问题描述

下面的代码和在什么情况下，Console.WriteLine（）的可能输出是什么？



static void检查（输出int a，out int b ）

{

a = 2;

b = 3;

Console.WriteLine（a == b）;

}



我的尝试：



当我在VS中运行它时，它只是给出了错误的答案。

但这是在一个谜题中被问到所以我认为这可能是真的可能，但在特定场景中我我期待着解释

What can be the possible output of Console.WriteLine() in below code and in what scenarios?

static void Check(out int a, out int b)
{
a = 2;
b = 3;
Console.WriteLine (a == b);
}

What I have tried:

as I ran it in VS , it simply gave false as the answer.
But this was asked in a puzzle so I think there would be true possible for this but in a specific scenario that I am looking forward to have the explanation for

推荐答案

当函数调用如下时返回True



int a;

检查（out a，out a）;



在所有其他情况下返回False。



这是在答案揭晓后我才知道的。 !!!

Returns True when function is called as below

int a;
Check(out a, out a);

Returns False in all other cases.

This is what I got to know after the answer was revealed. !!!

在我看来，t总是假的。



在这种方法中你总是设置为2和b为3.

之后你比较它们是否相等并且由于方法设置（a = 2，b = 3），它总是相同的。



在C＃中创建并使用各种方案进行测试以确保

In my opinion t is always false.

In this method you always set a to 2 and b to 3.
After that you compare if they are equal and thanks to the method settings (a=2, b=3), it is always the same.

Create this in C# and test with various scenarios to be sure tho

我认为访调员试图通过使用OUT关键字来混淆你。在程序中，它写成a = 2和b = 3，所以它显然是假的。

I think interviewer was trying to confuse you by using OUT keyword. As in the program it is written a=2 and b=3 so it will be false obviously.
