如何使 robocopy 在单独的线程中运行并使用 powershell 将其输出实时传输到文本框？

问题描述 投票：0回答：1

我目前正在开发一个个人项目，其目标是自动将歌曲文件从我的谷歌驱动器下载到游戏《克隆英雄》的本地文件夹。最终目标是拥有一个具有用户友好 GUI 的程序，这样我就可以与我的朋友分享它，因为如果我们想玩在线合作游戏，我们都需要相同的歌曲文件。

我使用 .bat 文件制作了一些以前的版本，该文件使用带有 /MIR 标志的 robocopy 函数将我的驱动器复制到本地“歌曲”文件夹。这是通过与每个人共享谷歌驱动器并让他们使用“桌面版谷歌驱动器”应用程序将共享驱动器安装在计算机上来实现的，这使得robocopy可以看到谷歌驱动器内容。

但是，正如您可以想象的那样，它不是很用户友好，并且需要每个用户编辑脚本以定位他们的歌曲目录和安装的谷歌驱动器快捷方式

现在，我通过制作一个 power shell 脚本（附在下面）来运行整个程序，这使得我可以使用 Windows 窗体作为基本 GUI，从而对其进行了改进。这是我第一次使用 power shell，我对它还很陌生，但我最终确实让它工作，唯一的主要缺点是在 robocopy 运行时表单冻结，并且你无法再实时看到输出。

但是，我想与下面列出的其他一些问题一起解决这个问题，所以我来这里寻求一些方向，并（如果允许）接受对代码的任何批评，以便我可以改进它。

我想要做出的主要改进：

  • 在单独的线程上运行 robocopy，这样它就不会挂起表单

  • 将 robocopy 的输出实时传输到“控制台日志文本框”

小改进（如果允许）：

  • 在 robocopy 写入数据的位置添加保护，因为如果用户选择包含重要数据的文件夹，它可能会因为 /MIR 标志而被覆盖

  • 调整表单大小

  • 将LBN.png图像编码到脚本中，这样它就不需要位于目录中

  • 将文件路径存储在一个 .txt 文件中，而不是多个（或其他更好的方式）

  • 将所有 GUI 创建代码放入单个函数中以提高可读性

  • 为robocopy添加进度条

代码：

我尝试搜索有关在单独的线程中运行 robocopy 并实时捕获输出的指南或旧帖子，但我发现的所有示例要么不适用于 robocopy，要么在同一线程中运行它，这会冻结表单它正在运行，并且仅在运行完成后将 robocopy 的输出放入文本框中。

Ian Kemp 提到使用 Visual Studio 创建一个独立的 EXE，链接 Here 可能就是他正在谈论的内容。还要考虑 mklemnt0 的 Start-ThreadJob 解决方案。看看这能让你走多远。至于保护，我建议不要完全使用 /MIR 标志。我只会做 /COPY:DATSOU 或类似的事情。当你处理像这样一般的事情时，尤其是处理你朋友的数据时，/MIR 太危险了。
