什么是一个单|或放大器;意思？ [英] What does a single | or & mean?

问题描述

可能重复：结果
的什么是之间的diffference |和|| ？或者运营商结果
是什么| （管）在C＃是什么意思？

我有一些代码，被写了另一名开发人员在办公室里，谁不是在此刻。我有一些工作要做他的代码，但我还没有碰到在此之前昏迷。我想在这里上搜索，但它去除我的|退出搜索线。我也不知道什么该符号的名称为，所以无法搜索它这样。

I have some code that was written by another developer in the office, who isn't in at the moment. I have some work to do on his code, but I have not coma across this before. I tried searching on here, but it strips my | out of the search line. I also don't know what the name for that symbol is, so couldn't search for it like that.

this.Action.Values[key] = (int)this.Action.Values[key] | 1;

我的问题是什么呢单一或做在这种情况下？

My question is what does the single or do in this instance?

推荐答案

酒吧（或管道）， | 是一个逐位或运营商，并解释它的最简单的方法是，它可以让我们的标志相结合。试想一下：

The Bar (or pipe), | is a bit-wise OR operator, and the easiest way of explaining it is that it allows us to combine flags. Consider:

[Flags]
public enum WindowFlags
{
    None = 0, 
    Movable = 1,
    HasCloseBox = 2,
    HasMinimizeBox = 4,
    HasMaximizeBox = 8
}

使用按位或运算，我们可以结合的标志，正是如此：

Using the bitwise-OR operator, we can combine flags, thusly:

WindowFlags flags = WindowFlags .Movable | WindowFlags .HasCloseBox | WindowFlags .HasMinimizeBox;

我们可以测试对于给定的标志时，使用：

We can "test" for a given flag, using:

bool isMovable = (flags & WindowFlags .Movable);

删除标志更是一个应变对眼球有点：

Removing flags is a bit more of a strain on the eyeballs:

flags &= ~WindowFlags.HasCloseBox;  // remove HasCloseBox flag
