我想在 Windows 上创建一个 ISO 映像,即一个 .iso 文件。使用 COM 组件IMAPI2FS.MsftFileSystemImage可以做到这一点,我在题为“在 powershell 中使用 IMAPI 2 写入光盘”的 MSDN 博客文章中找到了有关如何使用 PowerShell 执行此操作的说明。

在第3步之后,那些说明说“在这一步你可以停止并将结果图像保存到本地硬盘,这将是一个纯iso图像。”

我的问题:如何在 PowerShell 中获取 $resultStream,即通过检索ImageStream产生的 COM 对象并将其内容保存到文件中?

您需要使用 FileStream 编写器。检查此链接以获取如何在 c# 中完成的示例。 http://tools.start-automating.com/Install-ExportISOCommand/?-Download

那里的功能可用于创建帮助您创建 ISO 的 cmdlet。例如,

运行Install-ExportISOCommand 这创建Export-Iso

然后,用于Export-ISO创建 ISO。

Export-Iso -ISOPath C:\dropbox\test.iso -FileName C:\Dropbox\Scripts

您可以使用DiscUtils 库制作ISO并管理其他磁盘格式,例如 VHD/VHDX、DMG、FAT 等)。支持PowerShell 模块以及MSBUILD 任务以在项目构建时自动创建 ISO。

创建一个CDBuilder对象并通过添加文件和目录进入城镇,然后使用该Build方法将其保存到磁盘。在此处下载文档

 CDBuilder builder = new CDBuilder();
 builder.AddFile("samplefile.txt", new byte[] { });
 builder.Build(@"c:\output.iso");

这种方法的好处是它是 100% 托管代码和跨平台 - 没有IMAPI2 COM/Marshaling 要求

这是我用过很多次的带有 GUI 的端到端 PowerShell ISO 创建器。无需额外的软件。
