我正在尝试自动化安装过程，在该过程中我卸载以前的版本并在顶部安装较新的版本.如果卸载成功，我应该如何测试(在我的引导程序中，用 C# 编码)?

I'm trying to automate an install process in which I uninstall a previous version and install a newer version over the top. How should I test (in my bootstrapper, coded in C#) if the uninstall was a success?

这就是我目前启动卸载的方式.

This is currently how I'm launching the uninstall.

Process p = Process.Start("msiexec", /*various switches*/); p.WaitForExit();

我目前也在纠结动态多实例，这真的让我心烦意乱，所以在 WiX 本身中处理这个问题即使不是不可能也很困难.

I'm also currently tangling with dynamic multiple instances, which really bend my mind, so handling this problem within WiX itself is difficult if not impossible.

推荐答案

您可以使用 Windows Installer API，而不是通过 msiexec 调用 Windows Installer.您可以通过 P/Invoke、激活 COM 接口或通过 WiX 的 DTF 包装库来做到这一点.用于删除产品的具体功能是 MsiConfigureProductEx.

Rather than invoke Windows Installer through msiexec, you can use the Windows Installer API. You can do that through P/Invoke, activating the COM interface or via WiX's DTF wrapper library. The specific function to use to remove a product is MsiConfigureProductEx.

使用 DTF，您可以这样做:

With DTF, you can do it like this:

Installer.SetInternalUI(InstallUIOptions.Silent); Installer.SetExternalUI(UiHandler, InstallLogModes.Verbose); Installer.EnableLog(InstallLogModes.None, null); Installer.ConfigureProduct(productCode, 0, InstallState.Removed, ""); Console.WriteLine("RebootRequired: {0} RebootInitiated: {1}", Installer.RebootRequired, Installer.RebootInitiated);

UiHandler 委托允许应用监控进度.如果有错误，DTF 会抛出异常.

The UiHandler delegate allows the app to monitor progress. If there is an error, DTF throws an exception.
