PowerShell参数值建议

Question

我已经用C＃编写了一个Cmdlet。是否可以提供特定字符串参数的所有可能值（此示例为“ PackageId”）？

public sealed class InstallPackageCommand : PSCmdlet
{
    [Parameter(Position = 0, Mandatory = true)]
    public string PackageId { get; set; }

    protected override void BeginProcessing()
    {
       //...
    }
}

您可以将ValidateSetAttributeon属性用于该参数，例如：

[ValidateNotNullOrEmpty]
[ValidateSet(new string[] {"a","b","c"})]
[Parameter(Position = 0, Mandatory = true)]
public string PackageId { get; set; }
