如何在mongodb asp.net核心的操作过滤器中设置动态连接字符串

"MongoDBConnection": {
  "ConnectionString": "mongodb://localhost:27017",
  "DatabaseName": "YourDatabaseName"
}

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using MongoDB.Driver;

public class Startup
{
    private readonly IConfiguration _configuration;

    public Startup(IConfiguration configuration)
    {
        _configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        // 获取连接字符串配置项
        var connectionString = _configuration.GetSection("MongoDBConnection:ConnectionString").Value;
        var databaseName = _configuration.GetSection("MongoDBConnection:DatabaseName").Value;

        // 注册MongoDB服务
        services.AddSingleton<IMongoClient>(new MongoClient(connectionString));
        services.AddScoped<IMongoDatabase>(x => x.GetRequiredService<IMongoClient>().GetDatabase(databaseName));

        // 其他服务配置...
    }

    // 其他方法...
}

using Microsoft.AspNetCore.Mvc;
using MongoDB.Driver;

public class MyController : Controller
{
    private readonly IMongoDatabase _database;

    public MyController(IMongoDatabase database)
    {
        _database = database;
    }

    public IActionResult Index()
    {
        // 使用动态连接字符串进行操作
        var collection = _database.GetCollection<MyModel>("MyCollection");
        // 其他操作...

        return View();
    }

    // 其他方法...
}
