Question

我正在一个创建GUI向导工具的项目中，此GUI向导工具首先从用户那里获取一些数据，并同时执行验证（例如连接性，DNS解析，API连接等）。 GUI向导工具从用户获取所有必需的数据之后，它将开始调用其他下标。

为了使GUI向导更快并克服此无响应性问题，我正在使用Runspaces，GUI本身将在Runspace中运行，并且其他任何任务（例如执行验证检查）也将在其他Runspace中运行。 / p>

为了简化代码并使代码更容易和更有条理，我使用了脚本块。我已经在GUI运行空间中创建了许多脚本块，每当单击GUI中的提交按钮时就可以使用。对于每个提交按钮，将有一个不同的脚本块，并且某些提交按钮将执行相同的脚本块。

我的问题是调用脚本块。每当我在Add_Click操作中添加脚本块时，脚本块都不会执行，我尝试在脚本块中使用Wait-Debugger，甚至看不到InBreakpoint状态下的任何运行空间。

请问我是否做错了什么，因为我是PowerShell中的运行空间和WPF的新手。谢谢您的帮助。

                $ExecScriptObject = $MPSB1PSSesion.BeginInvoke()
            })
#   Show Wizard Window.
        $Global:GuiHash.WizardMainWindow.ShowDialog() | Out-Null

    })  

    $ShowGui = $GuiPSSession.BeginInvoke()

我的期望是，当我单击输入框并在GUI上提供不正确的FQDN时，会因看到的问题而出错。

进行了几次测试和检查后，结果发现问题很简单，这都是我的错。当我调用AddScript时，我正在使用（{}），但是您应该只使用（）。因此，删除{}并将其设置为（）后，它可以正常工作。例如，

            $Global:GuiHash.WizardMainPageSubmitButton1.Add_Click({
                # Create new Runspace for this task. 
                $MPSB1Runspace = [runspacefactory]::CreateRunspace()
                $MPSB1PSSesion = [powershell]::Create()
                $MPSB1PSSesion.runspace = $MPSB1Runspace
                $MPSB1Runspace.Open()
                $MPSB1Runspace.SessionStateProxy.SetVariable("GuiHash",$Global:GuiHash)
                [void]$MPSB1PSSesion.AddScript($ScriptBlockMainPageSubmitButton1).AddArgument($Global:GuiHash)
                $ExecScriptObject = $MPSB1PSSesion.BeginInvoke()
            })

从不同的运行空间调用脚本块
