if (statement1) { # 执行语句1 } elseif (statement2) { # 执行语句2 } else { # 执行其他操作 } 在这个例子中,statement1和statement2是两个逻辑表达式,可以是任何返回布尔值的表达式。根据这两个语句的结果,程序将执行相应的代码块。 以下是对问题中提到的一些关键术语和概念的解释: 前端开发:前端开发涉...

The if() statement highlights what I said in my previous post which is that the value held in the string, $Stat, is not implicitly converted to its Boolean equivalent. Rather, PowerShell sees some random old string and performs an existence - or "not null" - check. ...
