这段C＃代码有什么作用？

What does result.IsVisible equal?

结果是什么.IsVisible相等?

    if(a==b)
        result.IsVisible = obj1.status.abc_REPORT == 'Y'
            && obj1.AnotherValue.ToBoolean() == false;

5 个解决方案

That depends on the values of obj1.status.abc_Report and obj1.AnotherValue.ToBoolean() (and it all depends on whether a==b or not).

这取决于obj1.status.abc_Report和obj1.AnotherValue.ToBoolean()的值(这一切都取决于是否a == b)。

I'm not quite sure of what the real question is here - which bit is confusing you?

我不太确定这里真正的问题是什么 - 这让你感到困惑?

One bit which may be confusing you is the shortcircuiting && operator (and possibly the lack of bracing!)

可能让你感到困惑的一点是短路&&运算符(可能缺少支撑!)

The && operator will only evaluate its right hand side if the left hand side evaluates to true: and the overall result of the expression is true if and only if both sides evaluates to true. (I'm assuming no strange user-defined conversions here.)

如果左侧的计算结果为true,则&&运算符仅评估其右侧:当且仅当双方的计算结果为true时,表达式的整体结果才为真。 (我假设这里没有奇怪的用户定义转换。)

So another way of writing it would be:

所以另一种写作方式是:

if (a == b)
{
    bool visibility = false;
    if (obj1.status.abc_REPORT == 'Y')
    {
        if (obj1.AnotherValue.ToBoolean() == false)
        {
            visibility = true;
        }
    }
    result.IsVisible = visibility;
}

Note that a condition comparing Booleans, like this:

请注意比较布尔运算的条件,如下所示:

obj1.AnotherValue.ToBoolean() == false

would usually be written like this:

通常会这样写:

!obj1.AnotherValue.ToBoolean()

(Note the exclamation mark at the start - the logical "not" operator.)

(注意开头的感叹号 - 逻辑“非”运算符。)

The same as this, in many less lines:

与此相同,在更少的行中:

if (a==b) {
    if (obj1.status.abc_REPORT == 'Y') {
         if (obj1.AnotherValue.ToBoolean() == false) {
             result.IsVisible = true;
         }
         else {
             result.IsVisible = false;
         }
    }
    else {
        result.IsVisible = false;
    }
}

#3

In simple words:

简单来说:

If a is equal to b:

如果a等于b:

result will be visible only if:

结果仅在以下情况下可见:

object1's status's abc_report is Yes(Y = Yes most probably) AND object1's other value cannot be converted to a Boolean

object1的状态是abc_report是(最可能是Y =是)AND object1的其他值无法转换为布尔值

#4

I'm guess result.IsVisible is a boolean

我猜测结果.IsVisible是一个布尔值

It will be true if the following conditions are true: obj1.status.abc_REPORT == 'Y' and obj1.AnotherValue.ToBoolean() == false

如果满足以下条件,则为真:obj1.status.abc_REPORT =='Y'和obj1.AnotherValue.ToBoolean()== false

Also, a == b must be true to enter the initial if

此外,a == b必须为true才能输入初始if

#5

lets go line by line:

让我们逐行:

  if(a==b)

obvious if value of a equals value of b the execute following line

显然,如果a的值等于执行以下行的b值

 result.IsVisible = obj1.status.abc_REPORT == 'Y'
        && obj1.AnotherValue.ToBoolean() == false;

result is some object (maybe winforms controls etc) which has a property IsVisible set it to true if obj1.status.abc_REPORT is equal to 'Y' and also obj1.AnotherValue.ToBoolean() is equal to false;

结果是一些对象(可能是winforms控件等),如果obj1.status.abc_REPORT等于'Y'并且obj1.AnotherValue.ToBoolean()等于false,则具有属性IsVisible将其设置为true;
