数字化招商管理系统全流程革新：旧系统评估→方案设计→开发→上线（附 30 天落地计划表）

// 招商管理系统架构示例
public class InvestmentSystemArchitecture
{
    // 前端：使用现代JavaScript框架
    public string FrontendFramework { get; set; } = "Vue.js";
    
    // 后端：使用.NET Core
    public string BackendFramework { get; set; } = "ASP.NET Core";
    
    // 数据库：使用SQL Server
    public string Database { get; set; } = "SQL Server";
    
    // ORM：使用Entity Framework Core
    public string ORMFramework { get; set; } = "EF Core";
}

// 使用EF Core Code First模式创建数据模型
public class InvestmentContext : DbContext
{
    public DbSet Merchants { get; set; }
    public DbSet Contracts { get; set; }
    public DbSet Projects { get; set; }
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // 配置实体关系和约束
        modelBuilder.Entity()
            .HasMany(m => m.Contracts)
            .WithOne(c => c.Merchant);
    }
}

// 商户实体
public class Merchant
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string ContactInfo { get; set; }
    public DateTime RegistrationDate { get; set; }
    public List Contracts { get; set; }
}

// 前端API调用示例（使用ES6+）
class InvestmentApi {
  // 获取商户列表
  async getMerchants(page = 1, pageSize = 10) {
    const response = await fetch(`/api/merchants?page=${page}&pageSize=${pageSize}`);
    return await response.json();
  }
  
  // 创建新商户
  async createMerchant(merchantData) {
    const response = await fetch('/api/merchants', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(merchantData)
    });
    return await response.json();
  }
}

// 使用示例
const api = new InvestmentApi();
const merchants = await api.getMerchants(1, 10);

// 商户API控制器示例
[ApiController]
[Route("api/[controller]")]
public class MerchantsController : ControllerBase
{
    private readonly InvestmentContext _context;
    
    public MerchantsController(InvestmentContext context)
    {
        _context = context;
    }
    
    // 获取商户列表
    [HttpGet]
    public async Task<><>>> GetMerchants(
        [FromQuery] int page = 1, 
        [FromQuery] int pageSize = 10)
    {
        var query = _context.Merchants.AsQueryable();
        var totalCount = await query.CountAsync();
        var items = await query
            .Skip((page - 1) * pageSize)
            .Take(pageSize)
            .ToListAsync();
            
        return new PagedList(items, totalCount, page, pageSize);
    }
    
    // 创建新商户
    [HttpPost]
    public async Task<>> CreateMerchant([FromBody] Merchant merchant)
    {
        if (!ModelState.IsValid)
            return BadRequest(ModelState);
            
        _context.Merchants.Add(merchant);
        await _context.SaveChangesAsync();
        
        return CreatedAtAction(nameof(GetMerchant), new { id = merchant.Id }, merchant);
    }
}
