 更新時間:2025年03月31日 09:43:25   作者:老胖閑聊  
Cursor 是一款功能強(qiáng)大的代碼編輯器,它憑借其人工智能輔助功能,為開發(fā)者帶來了諸多便利,本文將給大家介紹了用Cursor 進(jìn)行C#編程的超詳細(xì)指南,需要的朋友可以參考下

一、環(huán)境配置深度說明

1. .NET SDK版本管理

# 查看已安裝版本
dotnet --list-sdks

# 全局設(shè)置默認(rèn)版本
dotnet new globaljson --sdk-version 8.0.301
  • Cursor集成:在設(shè)置中指定SDK路徑(File > Preferences > Settings > .NET SDK Path

2. C#擴(kuò)展配置

  • 必裝插件
    • C# Dev Kit(官方智能感知)
    • NuGet Package Manager(依賴管理)
    • EF Core Power Tools(數(shù)據(jù)庫逆向工程)
  • 調(diào)試配置:在.vscode/launch.json中添加:
{
  "configurations": [
    {
      "name": ".NET Core Launch (web)",
      "type": "coreclr",
      "request": "launch",
      "preLaunchTask": "build",
      "program": "${workspaceFolder}/bin/Debug/net8.0/YourProject.dll",
      "args": [],
      "cwd": "${workspaceFolder}",
      "stopAtEntry": false,
      "serverReadyAction": {
        "action": "openExternally",
        "pattern": "\\bNow listening on:\\s+(https?://\\S+)"
      }
    }
  ]
}

二、進(jìn)階案例:構(gòu)建完整CRUD應(yīng)用

案例目標(biāo):開發(fā)一個圖書管理API,包含JWT認(rèn)證和Swagger文檔

步驟1:生成基礎(chǔ)架構(gòu)

  • 輸入指令:
創(chuàng)建一個ASP.NET Core Web API項目,包含以下功能:
- 使用Entity Framework Core + SQLite
- 包含Book模型(Id:int, Title:string, Author:string, ISBN:string)
- 包含BooksController的CRUD端點(diǎn)
- 啟用Swagger
  • AI生成的Program.cs關(guān)鍵代碼:
builder.Services.AddDbContext<AppDbContext>(options => 
    options.UseSqlite(builder.Configuration.GetConnectionString("Default")));

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

步驟2:添加JWT認(rèn)證

  • 在對話窗口輸入:
為當(dāng)前項目添加JWT Bearer認(rèn)證,要求:
- 生成User模型(Username, PasswordHash)
- 添加AuthController的/login端點(diǎn)
- 在Swagger中顯示認(rèn)證按鈕
  • AI生成的JwtService.cs示例:
public class JwtService
{
    private readonly IConfiguration _config;
    
    public JwtService(IConfiguration config) => _config = config;

    public string GenerateToken(User user)
    {
        var key = new SymmetricSecurityKey(
            Encoding.UTF8.GetBytes(_config["Jwt:Key"]!));
        
        var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
        
        var token = new JwtSecurityToken(
            issuer: _config["Jwt:Issuer"],
            audience: _config["Jwt:Audience"],
            claims: new[] { new Claim(ClaimTypes.Name, user.Username) },
            expires: DateTime.Now.AddHours(1),
            signingCredentials: creds);
        
        return new JwtSecurityTokenHandler().WriteToken(token);
    }
}

步驟3:數(shù)據(jù)驗證增強(qiáng)

  • 選中Book模型類,輸入:
為Book模型添加數(shù)據(jù)注解驗證:
- Title長度1-100字符
- ISBN必須符合正則表達(dá)式^\d{3}-\d{10}$
- Author不能為空
  • 生成結(jié)果:
public class Book
{
    public int Id { get; set; }
    
    [Required]
    [StringLength(100, MinimumLength = 1)]
    public string Title { get; set; }
    
    [Required]
    [RegularExpression(@"^\d{3}-\d{10}$", 
        ErrorMessage = "ISBN格式應(yīng)為XXX-XXXXXXXXXX")]
    public string ISBN { get; set; }
    
    [Required]
    public string Author { get; set; }
}

三、調(diào)試與測試深度集成

1. AI輔助調(diào)試

  • 錯誤診斷:將編譯錯誤信息復(fù)制到對話窗口,輸入解釋此錯誤并提供修復(fù)方案
CS1061: 'AppDbContext' does not contain a definition for 'Books'...
  • AI響應(yīng)示例:
該錯誤表明DbContext缺少DbSet<Book>屬性。解決方案:
1. 在AppDbContext中添加:
   public DbSet<Book> Books { get; set; }
2. 執(zhí)行遷移命令:
   dotnet ef migrations add AddBooksTable
   dotnet ef database update

2. 單元測試生成

  • 新建BookServiceTests.cs,輸入:
使用xUnit為BookService編寫測試:
- 測試GetAllBooks返回空列表當(dāng)數(shù)據(jù)庫為空
- 測試CreateBook返回正確ISBN
  • AI生成示例:
public class BookServiceTests : IDisposable
{
    private readonly AppDbContext _context;

    public BookServiceTests()
    {
        var options = new DbContextOptionsBuilder<AppDbContext>()
            .UseSqlite("DataSource=:memory:")
            .Options;
        
        _context = new AppDbContext(options);
        _context.Database.OpenConnection();
        _context.Database.EnsureCreated();
    }

    [Fact]
    public async Task GetAllBooks_ReturnsEmptyList_WhenNoBooks()
    {
        var service = new BookService(_context);
        var result = await service.GetAllBooks();
        Assert.Empty(result);
    }
}

四、企業(yè)級開發(fā)規(guī)范

1. 架構(gòu)模式引導(dǎo)

輸入指令示例:

使用Clean Architecture重構(gòu)當(dāng)前項目,包含:
- Application層(MediatR + AutoMapper)
- Infrastructure層(EF Core實(shí)現(xiàn))
- API層(Minimal API端點(diǎn))

AI將生成:

// Application/Books/Queries/GetAllBooks.cs
public record GetAllBooksQuery : IRequest<List<BookDto>>;

public class GetAllBooksHandler : IRequestHandler<GetAllBooksQuery, List<BookDto>>
{
    private readonly IApplicationDbContext _context;
    private readonly IMapper _mapper;

    public GetAllBooksHandler(IApplicationDbContext context, IMapper mapper)
    {
        _context = context;
        _mapper = mapper;
    }

    public async Task<List<BookDto>> Handle(GetAllBooksQuery request, CancellationToken ct)
    {
        return _mapper.Map<List<BookDto>>(
            await _context.Books.ToListAsync(ct));
    }
}

2. 性能優(yōu)化指導(dǎo)

輸入:

優(yōu)化數(shù)據(jù)訪問層:
- 為GetBookById添加AsNoTracking
- 在查詢中使用ProjectTo自動映射DTO
- 添加內(nèi)存緩存策略

AI生成:

public async Task<BookDto> GetBookById(int id)
{
    return await _memoryCache.GetOrCreateAsync($"book_{id}", async entry =>
    {
        entry.AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(5);
        return await _context.Books
            .AsNoTracking()
            .Where(b => b.Id == id)
            .ProjectTo<BookDto>(_mapper.ConfigurationProvider)
            .FirstOrDefaultAsync();
    });
}

五、企業(yè)級項目注意事項(補(bǔ)充)

  • 安全規(guī)范

    • 使用[Authorize(Policy = "RequireAdmin")]進(jìn)行細(xì)粒度權(quán)限控制
    • appsettings.json中隔離敏感信息,通過dotnet user-secrets管理
dotnet user-secrets init
dotnet user-secrets set "Jwt:Key" "YourSecureKeyHere"
  • CI/CD集成
    • 在對話窗口輸入生成GitHub Actions配置用于構(gòu)建和部署到Azure,AI將生成:
name: .NET Core CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
    - name: Setup .NET
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: 8.0.x
    - name: Restore dependencies
      run: dotnet restore
    - name: Build
      run: dotnet build --configuration Release --no-restore
  • 代碼質(zhì)量管控
    • 輸入添加SonarQube靜態(tài)分析配置,生成:
<PropertyGroup>
  <SonarQubeExclude>**/Migrations/**</SonarQubeExclude>
  <SonarQubeTestProject>false</SonarQubeTestProject>
</PropertyGroup>

六、Cursor高級功能挖掘

  • 代碼可視化

    • 輸入生成Book類的UML類圖,AI輸出PlantUML代碼:
@startuml
class Book {
  +int Id
  +string Title
  +string Author
  +string ISBN
}
@enduml
    • 安裝PlantUML擴(kuò)展直接預(yù)覽
  • SQL轉(zhuǎn)換

    • 輸入將以下LINQ轉(zhuǎn)換為原生SQL
context.Books.Where(b => b.Author == "J.R.R. Tolkien").OrderBy(b => b.Title)
  • AI輸出:
SELECT * FROM Books 
WHERE Author = 'J.R.R. Tolkien' 
ORDER BY Title ASC
  • 多模態(tài)開發(fā)
    • 上傳界面草圖,輸入根據(jù)此UI生成WPF XAML代碼,AI生成:
<Window>
  <Grid>
    <DataGrid ItemsSource="{Binding Books}">
      <DataGrid.Columns>
        <DataGridTextColumn Header="Title" Binding="{Binding Title}"/>
      </DataGrid.Columns>
    </DataGrid>
  </Grid>
</Window>

以上補(bǔ)充內(nèi)容覆蓋了企業(yè)級開發(fā)的完整生命周期。實(shí)際使用時建議:

  • 分模塊逐步生成代碼
  • 對關(guān)鍵業(yè)務(wù)邏輯進(jìn)行人工復(fù)核
  • 建立項目級的cursor-context.md文件記錄常用提示詞模板

以上就是使用Cursor進(jìn)行C#編程的詳細(xì)步驟的詳細(xì)內(nèi)容,更多關(guān)于Cursor進(jìn)行C#編程的資料請關(guān)注腳本之家其它相關(guān)文章!
