When we need to perform multilevel checks we can use multiple if and else conditions or nested if-else branches but when we need to perform all conditional operations on a particular variable then it better to use switch case. Inshell scriptingswitch case is represented using keywords case and...
在PowerShell 中,switch 映射到 System.Management.Automation.SwitchParameter。4.2.6 枚举类型枚举类型是定义一组命名常量的类型,这些常量表示可以赋值给该枚举类型的对象的所有可能值。 在某些情况下,一组值一次只能表示一个值。 在其他情况下,这组值是两个不同的幂,通过使用 -bor 运算符 (§7.8.5),可以在...

第一點是我新增了 –ComObject 參數,將 Windows PowerShell 指向 COM 架構,而不是 .NET 架構。第二點,我使用的是 COM ProgID,而不是 .NET 建構函式,在本例中,即 Scripting.FileSystemObject。ProgID 的名稱就跟您過去一直使用的一樣。對等的 VBScript 程式碼是:複製 ...
If the script were run with the –clear switch, the $clear variable would be present and, in that case, we would need to clear the event logs. Therefore, we use the if statement to determine whether the $clear variable is present: Copy if($clear) { Before we empty the event logs...
Unlike most scripting languages, note that in Windows PowerShell, even if your script is in the current working directory, you still have to specify the path to the script using either a relative path (as I've done) or a full path. This is for security purposes. Additionally, Windows ...
The switch statement lists each condition and an optional action. If a condition obtains, the action is performed.Syntax 1:Syntax Kopeeri switch [-regex|-wildcard|-exact][-casesensitive] ( <value> ) { <string>|<number>|<variable>|{ <expression> } {<statement list>} <string>|<number...
If no parameters are used, switch behaves the same as using the Exact parameter. It performs a case-insensitive match for the value. If the value is a collection, each element is evaluated in the order in which it appears. The switch statement must include at least one condition statement....
Scripting Tools Test-Expression The primary command can be used to test a PowerShell expression or scriptblock for a specified number of times and calculate the average runtime, in milliseconds, over all the tests. Why When you run a single test with Measure-Command the result might be affect...
