以下是实现CI/CD链路的C#代码，涵盖构建、测试、部署等关键环节的自动化流程：

基础项目结构

// Program.cs 示例入口
public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);
        builder.Services.AddControllers();
        var app = builder.Build();
        app.MapControllers();
        app.Run();
    }
}

单元测试示例

// Tests/CalculatorTests.cs
using Xunit;

public class CalculatorTests
{
    [Fact]
    public void Add_TwoNumbers_ReturnsSum()
    {
        var calculator = new Calculator();
        var result = calculator.Add(2, 3);
        Assert.Equal(5, result);
    }
}

public class Calculator
{
    public int Add(int a, int b) => a + b;
}

CI/CD 配置文件

# .github/workflows/dotnet-ci-cd.yml
name: .NET CI/CD Pipeline

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      
      - name: Setup .NET
        uses: actions/setup-dotnet@v3
        with:
          dotnet-version: '6.0.x'
          
      - name: Restore dependencies
        run: dotnet restore
        
      - name: Build
        run: dotnet build --no-restore --configuration Release
        
      - name: Test
        run: dotnet test --no-build --verbosity normal
        
      - name: Publish
        run: dotnet publish -c Release -o ./publish
        
      - name: Deploy to Azure Web App
        if: github.ref == 'refs/heads/main'
        uses: azure/webapps-deploy@v2
        with:
          app-name: 'your-app-name'
          publish-profile: ${{ secrets.AZURE_PUBLISH_PROFILE }}
          package: ./publish

Docker 集成

# Dockerfile
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY . .
RUN dotnet restore
RUN dotnet publish -c release -o /app

FROM mcr.microsoft.com/dotnet/aspnet:6.0
WORKDIR /app
COPY --from=build /app .
ENTRYPOINT ["dotnet", "YourApp.dll"]

关键组件说明

• GitHub Actions：自动化执行构建、测试和部署
• Azure Web Apps：托管部署目标（可替换为AWS/其他服务）
• Docker：容器化部署方案
• xUnit：单元测试框架

实际使用时需替换your-app-name和密钥配置，并根据项目需求调整工作流步骤。
