上面应该将实际的 C# dll 编译到 MSI 中.您可以在 Orca 中打开 MSI 并在二进制表中查看.

The above should compile the actual C# dll into the MSI. You can open the MSI in Orca and see in the Binary table.

不是很好，但我喜欢添加对 System.Windows.Forms 的引用并使用 MessageBox.Show 在自定义操作中显示一个对话框，以确保它按预期运行.我还为在调试模式下构建的 dll 添加了应用程序调试器启动命令.这样一来，Visual Studio 将被自动调用(如果一切正常)，因此可以单步执行代码.

It is not great, but I like to add a reference to System.Windows.Forms and use a MessageBox.Show to show a dialog from within the custom action to ensure it is running as expected. I also add the application debugger launch command for dlls built in debug mode. That way Visual Studio will be automatically invoked (if all works correctly) so the code can be stepped through.

通过右键单击 C# 项目的引用节点添加对 System.Windows.Forms" 的引用，然后添加 "System.Windows.Forms".还将 "using System.Windows.Forms;" 添加到源文件的顶部 - 请参阅下面的完整源代码.关键是要记住在项目级别引用 System.Windows.Forms".

Add the reference to "System.Windows.Forms" by right clicking the C# project's Reference node and then add "System.Windows.Forms". Also add "using System.Windows.Forms;" to the top of the source file - see full source below. The key is to remember to reference "System.Windows.Forms" at a project level.

现在将其作为测试代码添加到自定义操作项目的 CustomAction1" 自定义操作代码片段(完整源代码请参见底部的代码部分):

Now add this as test code to the custom action project's "CustomAction1" custom action code snippet (see code section towards bottom for full source):

   // will launch the debugger for debug-build dlls
   #if DEBUG
     System.Diagnostics.Debugger.Launch();
   #endif

   MessageBox.Show("hello world");

要获得标准设置 GUI(对于阅读此内容的其他人)，请添加对 WiXUIExtension 如此处所述(这是创建可编译并具有 GUI 的基本 WiX 项目的分步操作)，然后将其注入您的源代码:

To get a standard setup GUI (for others who read this), add a reference to WiXUIExtension as explained here (that is a step-by-step for creating a basic WiX project that compiles and has a GUI), and then inject this into your source:

 <UIRef Id="WixUI_Mondo" />

我喜欢将 <MediaTemplate/> 更改为 <MediaTemplate EmbedCab=yes"/> 避免使用外部源 cab 文件(通过此更改，cab 被编译到 MSI 中).

I like to change <MediaTemplate /> to <MediaTemplate EmbedCab="yes" /> to avoid external source cab files (with this change cabs are compiled into the MSI).

如果您没有添加任何组件，您可以添加它以将 notepad.exe 包含在您的 MSI 中，以便在目录 下进行测试安装INSTALLFOLDER(只是在没有可用源文件的情况下安装某些东西的技巧 - 应该在任何机器上解析的源路径) - 替换整个TODO"部分 - 请参阅下面的完整来源:

If you don't have any components added, you can add this to include notepad.exe in your MSI for test installation under directory INSTALLFOLDER (just a trick to install something without having source files available - a source path that should resolve on any machine) - replace the whole "TODO" section - see full source below:

 <Component Feature="ProductFeature">
   <File Source="$(env.SystemRoot)
otepad.exe" />
 </Component>

现在我们需要声明实际的自定义操作并将其插入到安装序列中.让我们在前面的 <Binary> 下添加它.元素:

 <CustomAction Id="CA1" BinaryKey="CustomActions" DllEntry="CustomAction1"/>

 <InstallUISequence>
   <Custom Action="CA1" After="CostFinalize" />
 </InstallUISequence>

 <InstallExecuteSequence>
   <Custom Action="CA1" After="CostFinalize" />
 </InstallExecuteSequence>

现在构建并测试运行 MSI.您应该会收到大量 hello world" 消息.

Now build and test run the MSI. You should get numerous "hello world" messages.

这是 C#/托管代码自定义操作的整体 心跳" - 我有时使用它们的方式.

That is the overall "heartbeat" of a C# / managed code custom action - the way I sometimes use them.

WiX Source Actual:现在，合成 - 记得替换所有 GUID！:

构造:$(env.SystemRoot) - 在下面的 WiX 源中 -获取环境变量 %SystemRoot% - 解析为C: 在大多数系统上(列出环境变量打开一个 cmd.exe并键入 set 并按 Enter).因此，以下来源应无需修改即可在所有系统上编译:

The construct: $(env.SystemRoot) - in the WiX source below - gets the environment variable %SystemRoot% - which resolves to C: on most systems (to list environment variables open a cmd.exe and type set and press Enter). The below source should hence compile on all systems without modifications:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Product Id="*" Name="DemoCA" Language="1033" Version="1.0.0.0" Manufacturer="test" UpgradeCode="0adf972a-5562-4a6f-a552-dd1c16761c55">
        <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" />

        <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
        <MediaTemplate EmbedCab="yes" />
    
    <UIRef Id="WixUI_Mondo" />

 <!-- START CUSTOM ACTION CONSTRUCTS -->
    
    <Binary Id="CustomActions" SourceFile="$(var.CustomAction1.TargetDir)$(var.CustomAction1.TargetName).CA.dll" />

    <CustomAction Id="CA1" BinaryKey="CustomActions" DllEntry="CustomAction1"/>

    <InstallUISequence>
      <Custom Action="CA1" After="CostFinalize" />
    </InstallUISequence>

    <InstallExecuteSequence>

    </InstallExecuteSequence>

 <!-- END CUSTOM ACTION CONSTRUCTS -->

步骤简介:所需更改的简短摘要:

Steps-in-brief: short summary of changes needed:

1. 将制造商字段设置为某些内容.
2. 如上所示添加和修改自定义操作结构.
3. 向底部添加组件/文件元素，替换TODO"部分.
4. 如上所述，将 MediaTemplate 设置为使用嵌入式 cab(可选，不是示例运行所必需的).

自定义操作代码:最后是实际的 C# 自定义操作测试代码 - 使用 Debugger.Launch 更新，它将为调试构建 DLL 启动调试器.然后，您可以将调试器附加到正确的源项目并逐步执行代码:

Custom Action Code: And finally the actual C# custom action test code - updated with Debugger.Launch which will launch the debugger for a debug-build DLL. You can then attach the debugger to the correct source project and step-through the code:

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;
using System.Windows.Forms;

namespace CustomAction1
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult CustomAction1(Session session)
        {

#if DEBUG
            System.Diagnostics.Debugger.Launch();
#endif

            MessageBox.Show("hello world");

            session.Log("Begin CustomAction1");

            return ActionResult.Success;
        }
    }
}
