Question

我遇到了返回正确输出的脚本问题：

   public partial class MainWindow : Window
{
    TaskViewModel viewModel = new TaskViewModel();

    public MainWindow()
    {
        this.DataContext = viewModel;
        InitializeComponent();
        Server_V2.AsyncService.runMain();
        DisplayAV();
    }

    //Display Availability
    private async void DisplayAV() {
        while (true) {
            //availabilityField.Text = Server_V2.AV.ToString();
            viewModel.Availability = Server_V2.AV.ToString();
            await Task.Delay(500);
        }
    }

    public class TaskViewModel : INotifyPropertyChanged
    {
        private string availabilty = "0";
        public string Availability
        {
            get { return availabilty; }
            set { availabilty = value; OnStaticPropertyChanged();}
        }
        public event PropertyChangedEventHandler PropertyChanged;
        public void OnStaticPropertyChanged([CallerMemberName] string PropertyName = null)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(PropertyName));
        }
    }

由于某种原因 - 我继续回来＆＃34; Maximiser Installed＆＃34;和＃34;提供商ID已配置＆＃34;即使他们不是。我错过了一些重要的东西吗？

修改如果找到了我的答案（因为我们有多个providerID＆＃39; s）使用：

$maximiser = Get-ChildItem -Path C:\Windows\System32\maximiser.tsp | select Name
$ID6 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID6 
$ID5 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID5
$ID4 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID4
$ID3 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID3
$ID2 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID2
$ID1 = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID1
$ID = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' | select ProviderID
$nomax = "Maximiser no installed"
$noid = "ProviderID not configured"
Write-Host 'This Computer is called' $env:COMPUTERNAME 
if ($maximiser = $maximiser) {
write-host "Maxmiser installed"}
Else {write-host "$nomax"}
if ($ID6 = $ID6 ) {
write-host "Provider ID Configured"}
Elseif ($ID5 = $ID5) {
write-host "Provider ID Configured"}
Elseif ($ID4 = $ID4) {
write-host "Provider ID Configured"}
Elseif ($ID3 = $ID3) {
write-host "Provider ID Configured"}
Elseif ($ID2 = $ID2) {
write-host "Provider ID Configured"}
Elseif ($ID1 = $ID1) {
write-host "Provider ID Configured"}
Elseif ($ID = $ID) {
write-host "Provider ID Configured"} 
Else {Write-Host "Provider ID not Configured"}

这似乎有效！

Answer 1

Powershell中的正确表示法是“-eq”而不是“=”。

使用“=”分配值，而不是比较它。

此外，“$ something -eq $ something”永远不会评估为$ false。它总是等于它自己，即使变量根本没有值。

Answer 2

像这样......

<input type="text" ng-model="vm.input.value" ng-paste="vm.pasteInput($event)" />

......当前状态应该有效。

此外，您不需要将相同的数据7次提取到不同的变量中......它会在那里。

If ($ID.ProviderID -ne $null) {

    # Action if  ProviderID in 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\' doesnt has a value.

}

...将导致......

$ID = Get-Itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\Providers\'

...拥有比较所需的数据。

如果/ elseif给出了错误的输出
