选项卡-完成Powershell Cmdlet的ValidateSet

Question

我正在使用C#创建PowerShell cmdlet。对于其中一个参数，我使用validateset。

[ValidateNotNullOrEmpty]
[ValidateSet(new string[]{"STANDARD", "CUSTOM","MINIMUM","DEFAULT"},IgnoreCase=true)]
[Parameter(
    Mandatory = true,
    ValueFromPipelineByPropertyName = false,
    ValueFromPipeline = false,
    HelpMessage = "House Mode")
]
[Alias("hm")]
public string HouseMode
{
    get { return m_housemode; }
    set { m_housemode = value;  }
}   

如何使validateset的值出现在制表符完成列表中？

Answer 1

这来自pscx中的Format-Hex命令：

[Parameter(ParameterSetName = ParameterSetObject,
           ValueFromPipelineByPropertyName = true,
           HelpMessage = "The encoding to use for string InputObjects.  Valid values are: ASCII, UTF7, UTF8, UTF32, Unicode, BigEndianUnicode and Default.")]
[ValidateNotNullOrEmpty]
[ValidateSet("ascii", "utf7", "utf8", "utf32", "unicode", "bigendianunicode", "default")]
public StringEncodingParameter StringEncoding
{
    get { return _encoding; }
    set { _encoding = value; }
}

选项卡补全对此参数有效。在您的情况下，我认为您希望像这样指定属性：

[ValidateSet("STANDARD", "CUSTOM","MINIMUM","DEFAULT", IgnoreCase = true)]
