单行if语句，如何转换这个if-else-statement [英] One-liner if statements, how to convert this if-else-statement

问题描述

这里完全是菜鸟，所以要温柔.我到处找，似乎找不到答案.我如何压缩以下内容?

Total noob here so be gentle. I've looked everywhere and can't seem to find the answer to this. How do I condense the following?

if (expression)
{
    return true;
}
else
{
    return false;
}

我无法让它工作，因为它正在返回一些东西而不是设置一些东西.我已经看到过这样的事情:

I can't get it to work since it's returning something vs. setting something. I've already seen things like this:

somevar = (expression) ? value1 : value2;

就像我说的，请温柔:)

Like I said, please be gentle :)

推荐答案

return (expression) ? value1 : value2;

如果 value1 和 value2 实际上是 true 和 false 就像在你的例子中一样，你也可以

If value1 and value2 are actually true and false like in your example, you may as well just

return expression;
