首先，我们看看您是否是管理员，因为不是每个人都是。

Question

该脚本是一个简单的管理工具，用于指示三个Windows服务的状态并切换它们。

一切正常但我没有完成它来实现GUI的刷新。

我想在标签中显示相关状态并隐藏不可点击的按钮。到目前为止我用计时器玩，但GUI仍然没有刷新..

首先，我必须说你的代码需要大量的TLC。您不应该标记按钮或标签1-20。使代码看起来很混乱，在15天后，您将不知道代码说的是什么。在第2-4和128-130行，您将变量定义两次。

我现在所做的就是创建这个服务GUI，它不仅可以帮助您，还可以帮助您完成相同类型的任务。您可以将所需的服务添加到Param函数中。

首先，我们看看您是否是管理员，因为不是每个人都是。

Add-Type -AssemblyName System.Windows.Forms
function Test-Admin {
  $currentUser = New-Object Security.Principal.WindowsPrincipal $([Security.Principal.WindowsIdentity]::GetCurrent())
  $currentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)
}
if ((Test-Admin) -eq $false)  {
    if ($elevated) 
    {
        # tried to elevate, did not work, aborting
    } 
    else {
        Start-Process powershell.exe -Verb RunAs -ArgumentList ('-noprofile -noexit -file "{0}" -elevated' -f ($myinvocation.MyCommand.Definition))
}

exit
}

我们创建了一个具有参数的中心位置。

请注意，您看到我使用$Global:您可以在此处阅读： https://msdn.microsoft.com/en-us/powershell/reference/3.0/microsoft.powershell.core/about/about_scopes

Function Param{
$Global:Option1 = get-service "Hamachi2Svc"
$Global:Option2 = get-service "NitroUpdateService"
$Global:Option3 = get-service "TeamViewer"

$Global:Option1Txt=$Global:Option1.Displayname
$Global:Option2Txt=$Global:Option2.Displayname
$Global:Option3Txt=$Global:Option3.Displayname
}

现在我们创建表单

Function ServiceAdminForm {
    $Form.Close()
    $Form.Dispose()
    Test-Admin
    MakeForm
}

现在我们定义按钮将使用的功能。

Function Option1 {
if ($Global:Option1.Status -eq "Running"){ Stop-Service $Global:Option1
}
else {Start-Service $Global:Option1}
}

Function Option2 {
if ($Global:Option2.Status -eq "Running"){ Stop-Service $Global:Option2
}
else {Start-Service $Global:Option2}
}

Function Option3 {
if ($Global:Option3.Status -eq "Running"){ Stop-Service $Global:Option3
}
else {Start-Service $Global:Option3}
}

Function Toggle {
if ($Global:Option1.Status -eq "Running") {$Global:Option1.stop()}
if ($Global:Option2.Status -eq "Running") {$Global:Option2.stop(); $Global:Option3.start()}
if ($Global:Option3.Status -eq "Running") {$Global:Option3.stop(); $Global:Option2.start()}
}

现在我们制作GUI的布局

调用参数和按钮功能。

Function MakeForm {
Param

    $script:Form = New-Object system.Windows.Forms.Form
    $Form.Text = "Service Administration"
    $Font = New-Object System.Drawing.Font("Times New Roman",12,[System.Drawing.FontStyle]::Bold)
    $Form.Font = $Font

    #Label for Option1
    $Global:Option1lbl = New-Object system.windows.Forms.Label
    $Global:Option1lbl.Text = $Global:Option1.Status
    $Global:Option1lbl.AutoSize = $true
    $Global:Option1lbl.Width = 25
    $Global:Option1lbl.Height = 10
    $Global:Option1lbl.location = new-object system.drawing.point(5,90)

    #Label for Option2
    $Global:Option2lbl = New-Object system.windows.Forms.Label
    $Global:Option2lbl.Text = $Global:Option2.Status
    $Global:Option2lbl.AutoSize = $true
    $Global:Option2lbl.Width = 25
    $Global:Option2lbl.Height = 10
    $Global:Option2lbl.location = new-object system.drawing.point(5,150)

    #Label for Option3
    $Global:Option3lbl = New-Object system.windows.Forms.Label
    $Global:Option3lbl.Text = $Global:Option3.Status
    $Global:Option3lbl.AutoSize = $true
    $Global:Option3lbl.Width = 25
    $Global:Option3lbl.Height = 10
    $Global:Option3lbl.location = new-object system.drawing.point(5,210)

    #Refresh/Reload
    $Reloadbtn = New-Object System.Windows.Forms.Button
    $Reloadbtn.Location = New-Object System.Drawing.Size(5,10)
    $Reloadbtn.AutoSize = $true
    $Reloadbtn.Text = "Reload"
    $Reloadbtn.Add_Click({ServiceAdminForm})

    #Toggle
    $Togglebtn = New-Object System.Windows.Forms.Button
    $Togglebtn.Location = New-Object System.Drawing.Size(80,10)
    $Togglebtn.AutoSize = $true
    $Togglebtn.Text = "Toggle"
    $Togglebtn.Add_Click({Toggle})

    #Button Option1
    $Global:Option1btn = New-Object System.Windows.Forms.Button
    $Global:Option1btn.Location = New-Object System.Drawing.Size(5,60)
    $Global:Option1btn.AutoSize = $true
    $Global:Option1btn.Text = "$Global:Option1Txt"
    $Global:Option1btn.Add_Click({Option1})

    #Button Option2
    $Global:Option2btn = New-Object System.Windows.Forms.Button
    $Global:Option2btn.Location = New-Object System.Drawing.Size(5,120)
    $Global:Option2btn.AutoSize = $true
    $Global:Option2btn.Text = "$Global:Option2Txt"
    $Global:Option2btn.Add_Click({Option2})

    #Button Option3
    $Global:Option3btn = New-Object System.Windows.Forms.Button
    $Global:Option3btn.Location = New-Object System.Drawing.Size(5,180)
    $Global:Option3btn.AutoSize = $true
    $Global:Option3btn.Text = "$Global:Option3Txt"
    $Global:Option3btn.Add_Click({Option3})

    #Form Controls
    $Form.Controls.Add($Global:Option1lbl)
    $Form.Controls.Add($Global:Option2lbl)
    $Form.Controls.Add($Global:Option3lbl)
    $Form.Controls.Add($Reloadbtn)
    $Form.Controls.Add($Togglebtn)
    $Form.Controls.Add($Global:Option1btn)
    $Form.Controls.Add($Global:Option2btn)
    $Form.Controls.Add($Global:Option3btn)
    $Form.ShowDialog()
}
MakeForm

也许某人有更好的刷新方法，但重新加载表单可以胜任。
