官方示例：https://kgithub.com/nacos-group/nacos-sdk-csharp

安装 Nuget 包

dotnet add package nacos-sdk-csharp.AspNetCore
dotnet add package nacos-sdk-csharp.Extensions.Configuration

配置 appsettings.json

{
    "Nacos": {
        "ServerAddresses": ["http://127.0.0.1:8848/"],
        //命名空间GUID,public默认没有
        "Namespace": "",
        "UserName": "nacos",
        "Password": "nacos",
        // 配置中心
        "Listeners": [
            {
                "Group": "dev",
                "DataId": "dotnet-nacos-service",
                "Optional": false
            }
        ],
        // 服务发现
        "ServiceName": "nacos-service",
        "GroupName": ".NET Core",
        // 权重
        "Weight": 100,
        "Metadata": {
            "aa": "bb",
            "cc": "dd"
        }
    }
}

添加服务和配置

using Nacos.AspNetCore.V2;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();

// 注册服务到Nacos
builder.Services.AddNacosAspNet(builder.Configuration, section: "Nacos");

// 添加配置中心
builder.Configuration.AddNacosV2Configuration(builder.Configuration.GetSection("Nacos"));

var app = builder.Build();

// Configure the HTTP request pipeline.

app.UseAuthorization();

app.MapControllers();

app.Run();

测试

using Microsoft.AspNetCore.Mvc;

namespace NacosDemo.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : ControllerBase
    {
        private IConfiguration _configuration;

        public WeatherForecastController(IConfiguration configuration) => _configuration = configuration;

        [HttpGet]
        [Route("get")]

        public string Get() => _configuration["RedisConn"];
    }
}
