简写如果声明：C＃ [英] shorthand If Statements: C#

问题描述

只是一个快速的，反正是有速记本？

Just a quick one, Is there anyway to shorthand this?

这基本上确定了方向右左或右，1为左，0

It's basically determining the direction left or right, 1 for left, 0 for right

在C＃中：

if (column == 0) { direction = 0; }
else if (column == _gridSize - 1) { direction = 1; }
else { direction = rand.Next(2); }

语句下面这将是：

The statement following this will be:

if (direction == 1)
{
    // do something
}
else
{
    // do something else
}

如果没有，它并没有真正物！只是好奇：）

If there isn't, it doesn't really matter! just curious:)

推荐答案

要使用简写来获得方向：

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

要简化完全的代码：

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}
