无法从托管引导程序应用程序 C# 代码中的引导程序变量读取输入 [英] Cannot read input from Bootstrapper variable in Managed Bootstrapper Application C#-Code

问题描述

我已使用托管引导程序应用程序对设置进行了编程.在我的解决方案中有以下项目:- Setup.msi:要安装的 MSI 项目- Setup.UI.dll:安装过程的 WPF-GUI- Bootstrapper.exe:引导程序项目- Launcher.exe:启动引导程序的 WPF 应用程序

I have programmed setup with a managed bootstrapper application. In my solution are the following projects: - Setup.msi : The MSI-project to install - Setup.UI.dll : The WPF-GUI for the installation process - Bootstrapper.exe : The bootstrapper-project - Launcher.exe : A WPF-app to start the bootstrapper

在引导程序包中，我为安装文件夹定义了一个变量:

In the bootstrapper bundle i have defined a variable for the installationfolder:

<Variable Name="INSTALLFOLDER"
          bal:Overridable="yes"
          Type="string"
          Value="[ProgramFilesFolder]"/>

这个变量可以在启动引导程序时由 Launcher 设置:

This variable can be set by the Launcher when starting the bootstrapper:

    Process proc = new Process();
    proc.StartInfo.FileName = "msiexec";
    proc.StartInfo.FileName = "..\\..\\..\\Bootstrapper\\bin\\Debug\\Bootstrapper.exe";
    proc.StartInfo.Arguments = "IsClientSetup=true INSTALLFOLDER=C:\\TestSetup";
    proc.Start();

如果我使用标准引导程序 (WixStandardBootstrapperApplication.RtfLicense)，我的给定条目将用于定义的变量 INSTALLFOLDER.我在安装过程中只看到引导程序对话框，但毕竟一切正常.

In case i'm using the standard bootstrapper (WixStandardBootstrapperApplication.RtfLicense) my given entry will be used in the defined variable INSTALLFOLDER. I see only the bootstrapper dialog while the installation process, but after all everythings fine.

但是当我使用托管引导程序(它启动我的 WPF-GUI)并尝试读取安装路径时，我总是从定义中获得默认值:程序文件文件夹.

But when i use the managed bootstrapper, which starts my WPF-GUI, and i try to read the installationpath, i always get the default from the definition: the programfilesfolder.

这里是包中的代码:

<WixVariable Id="WixMbaPrereqPackageId"
             Value="Netfx4Full" />
<WixVariable Id="WixMbaPrereqLicenseUrl"
             Value="NetfxLicense.rtf" />
<BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost" >
    <Payload Name='BootstrapperCore.config' SourceFile='..\..\..\Setup.UI\bin\Debug\BootstrapperCore.config' />
    <Payload SourceFile='..\..\..\Setup.UI\bin\Debug\SetupUI.dll' />
</BootstrapperApplicationRef>

<Chain>
    <MsiPackage Id="SetupPackage"
                SourceFile="..\..\..\Setup.Msi\bin\Debug\Setup.msi"
                Cache="yes"
                DisplayInternalUI="no"
                Vital="yes"
                Compressed="no"
                EnableFeatureSelection="no"
                DisplayName="SetupForTest">
        <MsiProperty Name="INSTALLLOCATION"
                     Value="[INSTALLFOLDER]" />
</Chain>

以及来自 SetupUI 中的 ViewModel 的代码:

And the code from the ViewModel in SetupUI:

string installationPath = UI.Model.Bootstrapper.Engine.FormatString(UI.Model.Bootstrapper.Engine.StringVariables["INSTALLFOLDER"]);

而且 - 至少 - SetupUI 中的 Run 方法:

And - at least - the Run-method in the SetupUI:

protected override void Run()
{
    MessageBox.Show("1 = " + this.Engine.FormatString(this.Engine.StringVariables["INSTALLFOLDER"]));
    Model = new Model(this);
    Model.Bootstrapper.Engine.Detect();
    MessageBox.Show("2 = " + Model.Bootstrapper.Engine.FormatString(Model.Bootstrapper.Engine.StringVariables["INSTALLFOLDER"]));

    RootViewViewModel viewModel = new RootViewViewModel();
    View = new RootView(viewModel);

    // Populate the view models with data then run the view..
    viewModel.Refresh();
    View.Run();

    this.Engine.Quit(0);
}

谁能告诉我，我做错了什么?

Can anybody tell me, what i have made wrong?

推荐答案

我自己找到了！代码是正确的，但在使用托管引导程序时，变量不会被覆盖.所以我们必须在 SetupUI 中从 BootstrapperApplication 的 CommandLineArguments 中读取它们并将它们设置在变量中.仅此而已.

I've found it myself! The code is correct, but when using a mannaged bootstrapper, the variables are not overwritten. So we have to read them in the SetupUI from the CommandLineArguments of the BootstrapperApplication and set them in the variable. That's all.
