powershell - 从for循环中调用Powershell函数

Question

我已经写了5个函数:

Function Task_1 {
‪#‎todo‬ 
}

Function Task_2 {
#todo 
}

同样。

现在，我想在for循环中一一调用这些函数:

for($i=1; $i -le 5; $i++){
Write-Host Executing Task $i;
Task_$i;
}

运行此命令时，输出为:

Executing Task 1

The term 'Task_$i' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

怎么了请解决!

Answer 1

Task_ $ i不是函数的名称，它只是一个字符串。

您可以先使用＆:

&Task_$i

或更确切地说:

invoke-expression Task_$i
