使用 XAML 将输出重定向到 PowerShell 中的文本框

Question

我正在使用 XAML 构建一个带有 GUI 的 PowerShell 脚本。我正在调用一个函数（形成一个 DLL 文件），它正在控制台中写入其输出，但我想让它改为在 TextBox 中写入。请参阅下图，了解当我单击按钮 CHECK DATA 时会发生什么，该按钮正在调用我为测试而创建的虚拟方法 set_Value。

我尝试使用redirections，但没有成功。我只能让它写入文件。我确定我遗漏了什么，但不确定是什么。

如果你们需要更多详细信息，请告诉我。

Answer 1

您需要 Text 属性。

$OutputBox.Text = set-Value

您必须在函数中将 Write-Host 更改为 Write-Output。
