Question

我有一个WIX安装程序自定义BA。在它里面我有2个按钮。在click事件处理程序中，我设置了一些变量，因此我只能确定需要安装的产品的哪些功能。当我执行InstallCommand时，它不会启动安装，而是日志说取消...

我的代码是......

this.InstallCommand = new DelegateCommand(() => this.model.PlanAction(LaunchAction.Install), () => this.State == InstallState.NotPresent);

public InstallView(InstallViewModel viewModel)
    {
        InitializeComponent();

        this.DataContext = viewModel;
        this.viewModel = viewModel;

        model = viewModel.model;

        this.Closed += (sender, e) => viewModel.CancelCommand.Execute(this);

    }

    private void btnInstallClientOnly_Click(object sender, RoutedEventArgs e)
    {
        model.SetInstallClient("InstallClient", 1);
        model.SetInstallServer("InstallServer", 0);

        if (viewModel.InstallCommand.CanExecute(null))
        {
            model.LogMessage("Executing Install Command");
            viewModel.InstallCommand.Execute(null);
        }

        this.Close();
    }

为什么安装不启动？它是通常绑定到按钮并且将开始安装的相同命令。

我可以执行以下行并且可行，但我不想重复代码。

model.PlanAction(Microsoft.Tools.WindowsInstallerXml.Bootstrapper.LaunchAction.Install);

谢谢，

无法从后面的代码执行ICommand
