使用一元数组运算符,将可枚举类型 Package 在数组中-这将防止PowerShell在构造将实际传递给方法的数组时解开字符串数组：

[TargetType]::printCustom(@(,'hello its working'.Split()))

让我们来测试一下：

# Generate test function that takes an array and expects it to contain string arrays

Add-Type @'
using System;

public class TestPrintCustom
{
  public static void printCustom(object[] args)
  {
    foreach(var arg in args){
      foreach(string s in (string[])arg){
        Console.WriteLine(s);
      }
    }
  }
}
'@

[TestPrintCustom]::printCustom(@(,"hello its working".Split()))

不出所料，它打印了：

hello
its
working
