function <函数名称> (<参数>) { <语句> } function <函数名称> { param(<参数>) <语句> } 函数的大括号和后面的语句可以写在一行中。 参数是一系列变量名称。在函数内修改参数不会修改外部同名变量的值(即使是数组也如此)。 参数可以指定类型,在参数前面加上“[<类型>]”即可强制把传入数据转换为该类型...
请勿使用这些参数名称:WhatIf、Confirm、Verbose、Debug、Warn、ErrorAction、ErrorVariable、OutVariable和OutBuffer。 此外,保留这些参数名称的以下别名:vb、db、ea、ev、ov和ob。 Name 是一个简单的通用参数名称,建议在 cmdlet 中使用。 最好选择类似于这样的参数名称,而不是对特定 cmdlet 唯一且难以记...

All variables from the call (dynamic) scope are visible when a function is executed. Proper closures really require lexical scoping. However, the GetNewClosure() method allows you to have some of the benefits of proper closures in a dynamically scoped language. Basically what it does is create...
In a function without a begin, process, or end block, the $input variable enumerates the collection of all input to the function. In the begin block, the $input variable contains no data. In the process block, the $input variable contains the current object in the pipeline. In the end...
