如何为现有PowerShell WinForms GUI添加文本框并输出脚本运行结果

你当前弹出独立窗口的核心原因是使用了Start-Process调用脚本，会启动独立的PowerShell进程运行，无法捕获输出。按以下方案修改即可实现输出内嵌展示： #

核心修改点 #

• 新增只读多行文本框用于展示脚本输出，匹配原有黑色界面风格
• 替换Start-Process调用逻辑，改用后台作业运行脚本，既不阻塞主界面，也能实时捕获所有输出（含报错信息）
• 补全原有代码遗漏的OKButton控件定义，修改后可直接运行

可选调整项 #

• 可自行修改$outputTextBox的Location和Size参数调整文本框的位置和大小
• 可修改ForeColor参数调整输出文字的颜色，比如改成白色、黄色等
• 如果脚本不需要实时输出，也可以直接用$output = & \\server1\folder1\script1.ps1 2>&1直接运行后一次性输出，代码更简单但运行时界面会暂时卡住
