将Powershell结果输出到RichTextBox

提前谢谢你的帮助

我有一个带有多个按钮的Powershell表单，这些按钮调用单独的函数。 这些功能将执行一系列任务

我似乎无法将执行结果（错误和所有错误）显示到我的Outputbox文本框中

相反，它进入了用于启动应用程序的powershell控制台，尝试了我在internet上能找到的所有方法，但我显然不理解如何做到这一点

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") 
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")  #loading the necessary .net libraries (using void to suppress output)
$form = New-Object System.Windows.Forms.Form 
$form.Text = "Azure Environment Build"
$form.Size = New-Object System.Drawing.Size(850,675) 
$form.StartPosition = "CenterScreen"

您没有在函数中与GUI文本框交互。文本

写入主机

在任何情况下都将使用PSHost控制台

然而，我发现有一件事很有用，那就是声明一个别名：

function Out-Gui($s) {
    $OutbutBox.AppendText($s);
}

Set-Alias -Name Write-Host  -Value Out-Gui  -Scope Global

这避免了相当多的复制（WinForms构造已经相当多了），并允许函数/脚本在CLI和GUI使用之间保持不变。（-顺便说一句，我对WPF有了更详细的说明。）

要捕获错误，您必须实现

try

/

catch

块、

陷阱

或捕获

-error变量

。覆盖默认值和流并不是那么简单。

覆盖。。。流并不是那么简单。

如果可能的话。非常感谢。然而，我认为这是我在#$Outputbox.Appendtext=New AzureRMResourceGroupDeployment-Name deployment-ResourceGroupName$ResourceINF-NET-01-TemplateFile行中尝试过的-Verbose@JoeAppendText是一个方法，不是要分配给的变量。如果您需要添加一些对象，也可以先通过

| Out String

将其强制转换。简单到$outputbox.appendtext='some stuff'| Out-String@Joe方法调用，不是赋值。非常感谢。然而，我认为这就是我在“#$Outputbox.Appendtext=New AzureRMResourceGroupDeployment-Name deployment-ResourceGroupName$ResourceINF-NET-01-TemplateFile-Verbose”行中尝试的但是它不起作用，因此#虽然失败了，但write host命令更多的是占位符，我实际上是在执行powershell命令，因此如果我能将控制台放在同样有效的窗体上。再次感谢
