Shay Levy在POWERSHELL SCRIPTING WITH [VALIDATESET]中的评论建议使用ValidateSet()
修饰PowerShell参数会导致标签符号完成:
在PowerShell中使用ValidateSet(或Enum类型)的一个好处 3.0是你在ValidateSet / Enum值上获得标签扩展。
我似乎无法在PowerShell函数或C#Cmdlet中使用它。
功能:
function Get-LogonToken {
[CmdletBinding()]
param(
[Parameter(Position = 0, Mandatory = $true)]
[ValidateNotNullOrEmpty()]
[string] $ServerName,
[Parameter(Position = 1, Mandatory = $true)]
[ValidateSet("secEnterprise", "secLDAP", "secWinAD")]
[string] $Authentication,
[Parameter(Position = 2, Mandatory = $true)]
[ValidateNotNullOrEmpty()]
[string] $Username,
[Parameter(Position = 3, Mandatory = $true)]
[ValidateNotNullOrEmpty()]
[SecureString] $Password
)
Write-Verbose "ServerName: $ServerName"
Write-Verbose "Authentication: $Authentication"
Write-Verbose "Username: $Username"
Write-Verbose "Password: $(ConvertFrom-SecureString $Password)"
...
}
的cmdlet:
[System.Management.Automation.Cmdlet(System.Management.Automation.VerbsCommon.Get, "LogonToken")]
[OutputType(typeof(System.String))]
public class GetLogonToken : System.Management.Automation.Cmdlet
{
[System.Management.Automation.Parameter(Position = 0, Mandatory = true)]
[ValidateNotNullOrEmpty]
public string ServerName
{
get { return server; }
set { server = value; }
}
private string server;
[System.Management.Automation.Parameter(Position = 1, Mandatory = true)]
[ValidateSet("secEnterprise", "secLDAP", "secWinAD")]
public string Authentication
{
get { return authentication; }
set { authentication = value; }
}
private string authentication;
[System.Management.Automation.Parameter(Position = 2, Mandatory = true)]
[ValidateNotNullOrEmpty]
public string Username
{
get { return username; }
set { username = value; }
}
private string username;
[System.Management.Automation.Parameter(Position = 3, Mandatory = true)]
[ValidateNotNullOrEmpty]
public SecureString Password
{
get { return password; }
set { password = value; }
}
private SecureString password;
...
}
的PowerShell:
PS> get-logontoken -verbose
cmdlet Get-LogonToken at command pipeline position 1
Supply values for the following parameters:
ServerName: server
Authentication: sec<tab> (nothing generated)
我错过了什么?
答案 0 :(得分:1)
感谢您发布单独的问题。现在我明白了问题所在。
当PowerShell提示您缺少Mandatory
值(在运行时)时,只有在您首次输入cmdlet时,才能完成标签:
Get-LogonToken -Authentication sec
TAB
