c# - Wix:托管 BA 命令行无效

Question

在玩 TestBA Bootstrapper from Bryan 时, 首先我安装了 1.0.0.0. 然后我将版本增加到 1.0.0.1 并记录了该过程。这是在升级期间传递 -uninstall -quite 命令行的部分:

问题:它不会安静地卸载，而是显示卸载对话框。如果我单击卸载，它将卸载 1.0.0.0，然后应用程序将升级到 1.0.0.1。

问题:如何让它理解其命令行参数并在不显示卸载对话框的情况下执行该过程？

我还在 WixBA 项目中咨询了 Wix 3.7 源代码，但其命令行处理仅处理 InstallFolder 参数。

非常感谢任何帮助，因为此升级方案会阻止我的 Bootstrapper 项目。

非常感谢。

关键是选择 -quiet 标志并且不显示 UI，而只是执行请求的操作。

这是通过 Bootstrapper 基类使用 DisplayMode 属性公开的，该属性使用 Display 枚举值。选项是

public enum Display
{
  Unknown,
  Embedded,
  None,
  Passive,
  Full,
}

然后您可以通过使用 LaunchAction 枚举的 Command.Action 值(同样在 Bootstrapper 基类中)确定要执行的操作。选项是:

public enum LaunchAction
{
 Unknown,
 Help,
 Layout,
 Uninstall,
 Install,
 Modify,
 Repair,

因此，我使用了一个名为 RunningSilent 的自定义属性来检测我不应显示 UI 的模式，然后如下所示使用它:

    /// <summary>
    /// True if running in silent display mode (ie: no UI).
    /// </summary>
    public virtual bool RunningSilent
    {
        get
        {
            return (DisplayMode != Display.Full && DisplayMode != Display.Passive);
        }
    }

    protected override void Run()
    {
        if (RunningSilent)
        {
             Log("Running without UI");
             LaunchAction requestedAction = Command.Action;
             //... this is an async call, so handle it accordingly.
             Engine.Plan(requestedAction);
             //... followed by Engine.Apply();

        }
        else
        {
            Log("Showing UI window");
            //.. Run your Managed UI
        }
    }
