运行if语句时,PowerShell 会将<test1>条件表达式计算为 true 或 false。 如果<test1>为 true,<statement list 1>则运行,PowerShell 退出 语句if。 如果<test1>为 false,则 PowerShell 将计算条件语句指定的<test2>条件。 有关布尔计算的详细信息,请参阅about_Booleans。

如果省略 语句列表,则结果是长度为零的不受约束的 1 维数组。否则,将对 statement-list 进行计算,并将作为计算一部分写入管道的任何对象按顺序收集在一个不受限制的一维数组中。 结果是(可能为空)不受约束的 1 维数组。例子:PowerShell 复制 $j = 20 @($i = 10) # 10 not written to pipeline, ...
