第12章：集成与自动化

12.1 Visual Studio 集成

12.1.1 安装扩展

扩展 → 管理扩展 → 搜索 ".NET Reactor"
下载并安装
重启 Visual Studio

12.1.2 项目配置

<!-- 在 .csproj 中添加 -->
<PropertyGroup>
  <ReactorEnabled>true</ReactorEnabled>
  <ReactorProject>protection.nrproj</ReactorProject>
</PropertyGroup>

<Target Name="ProtectAssembly" AfterTargets="Build" Condition="'$(Configuration)' == 'Release'">
  <Exec Command="&quot;$(ReactorPath)&quot; -file &quot;$(TargetPath)&quot; -project &quot;$(ReactorProject)&quot;" />
</Target>

12.1.3 构建后事件

Post-build event:
"C:\Program Files (x86)\Eziriz\.NET Reactor\dotNET_Reactor.Console.exe" ^
  -file "$(TargetPath)" ^
  -targetfile "$(TargetDir)Protected\$(TargetFileName)" ^
  -project "$(ProjectDir)protection.nrproj"

12.2 MSBuild 集成

12.2.1 自定义任务

<!-- ReactorTask.targets -->
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <UsingTask TaskName="ReactorTask" AssemblyFile="Reactor.MSBuild.dll" />
  
  <Target Name="ProtectWithReactor" AfterTargets="Build">
    <ReactorTask
      InputFile="$(TargetPath)"
      OutputFile="$(TargetDir)Protected\$(TargetFileName)"
      ProjectFile="$(ProjectDir)protection.nrproj"
      Obfuscation="true"
      NecroBit="true"
    />
  </Target>
</Project>

12.2.2 条件执行

<Target Name="ProtectAssembly" 
        AfterTargets="Build" 
        Condition="'$(Configuration)' == 'Release' AND '$(EnableReactor)' == 'true'">
  <!-- 保护逻辑 -->
</Target>

12.3 NuGet 包保护

12.3.1 打包前保护

<Target Name="ProtectBeforePack" BeforeTargets="Pack">
  <Exec Command="dotNET_Reactor.Console.exe -file $(TargetPath) ..." />
</Target>

12.3.2 自动化流程

1. 构建项目
   ↓
2. 保护程序集
   ↓
3. 创建 NuGet 包
   ↓
4. 发布到 NuGet

12.4 Docker 集成

12.4.1 Dockerfile

# Dockerfile
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src

# 复制项目文件
COPY ["MyApp/MyApp.csproj", "MyApp/"]
RUN dotnet restore "MyApp/MyApp.csproj"

# 复制源代码
COPY . .
WORKDIR "/src/MyApp"
RUN dotnet build -c Release -o /app/build

# 安装 .NET Reactor
COPY ["dotnet-reactor/", "/opt/dotnet-reactor/"]

# 保护程序集
RUN mono /opt/dotnet-reactor/dotNET_Reactor.Console.exe \
    -file /app/build/MyApp.dll \
    -targetfile /app/protected/MyApp.dll \
    -project protection.nrproj

# 最终镜像
FROM mcr.microsoft.com/dotnet/aspnet:8.0
WORKDIR /app
COPY --from=build /app/protected .
ENTRYPOINT ["dotnet", "MyApp.dll"]

12.5 自动化测试

12.5.1 单元测试

[TestClass]
public class ProtectedAssemblyTests
{
    [TestMethod]
    public void TestProtectedAssembly_LoadsSuccessfully()
    {
        // 加载保护后的程序集
        var assembly = Assembly.LoadFile("protected/MyApp.dll");
        Assert.IsNotNull(assembly);
    }
    
    [TestMethod]
    public void TestProtectedAssembly_FunctionalityWorks()
    {
        // 测试保护后的功能
        var type = assembly.GetType("MyApp.Calculator");
        var instance = Activator.CreateInstance(type);
        var method = type.GetMethod("Add");
        
        var result = method.Invoke(instance, new object[] { 2, 3 });
        Assert.AreEqual(5, result);
    }
}

12.5.2 集成测试

[TestClass]
public class ProtectionIntegrationTests
{
    [TestMethod]
    public void TestCompleteProtectionPipeline()
    {
        // 1. 构建项目
        BuildProject();
        
        // 2. 保护程序集
        ProtectAssembly();
        
        // 3. 验证保护
        VerifyProtection();
        
        // 4. 功能测试
        TestFunctionality();
    }
}

12.6 持续集成最佳实践

12.6.1 缓存优化

# GitHub Actions 示例
- name: Cache .NET Reactor
  uses: actions/cache@v3
  with:
    path: ~/.reactor
    key: ${{ runner.os }}-reactor-${{ hashFiles('**/protection.nrproj') }}

12.6.2 并行构建

strategy:
  matrix:
    configuration: [Debug, Release]
    platform: [x86, x64, AnyCPU]

steps:
- name: Protect Assembly
  run: |
    dotNET_Reactor.Console.exe \
      -file "bin/${{ matrix.configuration }}/${{ matrix.platform }}/MyApp.exe" \
      -project "protection-${{ matrix.platform }}.nrproj"

12.7 监控和报告

12.7.1 保护报告生成

# 生成 HTML 报告
dotNET_Reactor.Console.exe \
    -file MyApp.exe \
    -report protection-report.html \
    -reportformat html

12.7.2 统计信息

Protection Statistics:
- Total Methods: 1,547
- Protected Methods: 1,234 (80%)
- Encrypted Strings: 567
- Resource Files: 23
- Protection Time: 45 seconds
- File Size: 2.5 MB → 3.1 MB (+24%)

12.8 版本控制

12.8.1 .gitignore 配置

# .gitignore
# 排除保护后的文件
bin/Protected/
obj/Protected/

# 排除临时文件
*.nrlog
*.nrtemp

# 包含配置文件
!*.nrproj
!protection-config.xml

12.8.2 配置文件管理

推荐结构：
/
├── src/
│   ├── MyApp/
│   │   ├── MyApp.csproj
│   │   └── protection.nrproj
│   └── MyLibrary/
│       ├── MyLibrary.csproj
│       └── protection.nrproj
├── config/
│   ├── protection-debug.nrproj
│   ├── protection-release.nrproj
│   └── protection-production.nrproj
└── scripts/
    ├── protect.bat
    └── protect.ps1
