在某些语言中,可以在if语句后放置一行代码,它将会得以执行。 在 PowerShell 中情况并非如此。 必须提供带大括号的完整scriptblock才能使其正常工作。 比较运算符 if语句最常见的用法是比较两个项。 PowerShell 具有特殊运算符,可用于不同的比较方案。 当使用比较运算符时,会将左右两侧的值进行比较。 -eq(等于
if語句所做的第一件事就是計算括號中的運算式。 如果計算結果為$true,則會在大括號中執行scriptblock。 如果值是$false,則會略過該腳本區塊。 在上一個範例中,if語句只是評估$condition變數。 它是$true,並且會在腳本塊內執行Write-Output命令。 在某些語言中,您可以在if語句後面放置單行程序代碼,並執行它。

CredentialIf you supply a credential object to the –credential parameter, Windows PowerShell accepts it as is. This is great for interactive use, but what if you want to write an automated script for a cmdlet that accepts a –credential parameter? The solution lies in passing a preconstructed...

This DLL can be found both in the SDK and in the GAC, but if you don't have the SDK installed, don't worry about it. This little script can easily create the Snap-In assembly. The first thing that I need to do is create an alias for the C# compiler, once that is established ...
