Question

通常EXE版本在Bundle.wxs文件中设置。是否可以在Bootstrapper Application项目中获取此版本，其中编写了安装程序的后端引擎逻辑？我使用WPF创建了一个自定义UI。我需要在UI中显示该版本。我怎样才能做到这一点？请指教。下面是我的Bootstrapper应用程序代码。

    public class MainViewModel : ViewModelBase
    {
        private MINAClient minaClient;

        //constructor
        public MainViewModel(BootstrapperApplication bootstrapper)
        {

            this.IsThinking = false;

            this.Bootstrapper = bootstrapper;
            this.Bootstrapper.ApplyComplete += this.OnApplyComplete;
            this.Bootstrapper.DetectPackageComplete += this.OnDetectPackageComplete;
            this.Bootstrapper.PlanComplete += this.OnPlanComplete;
            this.Bootstrapper.DetectComplete += this.DetectComplete;

            this.Bootstrapper.CacheAcquireProgress += (sender, args) =>
            {
                this.cacheProgress = args.OverallPercentage;
                this.Progress = (this.cacheProgress + this.executeProgress) / 2;
            };
            this.Bootstrapper.ExecuteProgress += (sender, args) =>
            {
                this.executeProgress = args.OverallPercentage;
                this.Progress = (this.cacheProgress + this.executeProgress) / 2;
            };

            minaClient = new MINAClient();
            minaClient.initConnection("127.0.0.1", 9123);
        }

        #region Properties

Answer 1

var bundleVersion = Bootstrapper.Engine.VersionVariables["WixBundleVersion"];

使用Burn Bootstrapper项目内部获取应用程序版本
