通常 EXE 版本在 Bundle.wxs 文件中设置。是否可以在编写安装程序的后端引擎逻辑的 Bootstrapper 应用程序项目中获得此版本？我已经使用 WPF 创建了一个自定义 UI。我需要在 UI 中显示版本。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);
}
