以下是一个使用AspNet Core SignalR和Redux的示例代码，用于发送和接收数据：

1. 首先，在Startup.cs文件中配置SignalR：

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace SignalRWithReduxExample
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddSignalR();
            services.AddControllers();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapHub("/chatHub");
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

2. 创建一个名为ChatHub.cs的新类来处理SignalR连接：

using Microsoft.AspNetCore.SignalR;
using System.Threading.Tasks;

namespace SignalRWithReduxExample
{
    public class ChatHub : Hub
    {
        public async Task SendMessage(string user, string message)
        {
            await Clients.All.SendAsync("ReceiveMessage", user, message);
        }
    }
}

3. 在前端创建Redux store并配置SignalR连接：

import { createStore, applyMiddleware } from 'redux';
import { createHubConnection, addHubEventListener } from './signalrActions';
import rootReducer from './reducers';

// 创建Redux store
const store = createStore(
  rootReducer,
  applyMiddleware(thunk)
);

// 配置SignalR连接
store.dispatch(createHubConnection('/chatHub'));

// 添加SignalR事件监听器
store.dispatch(addHubEventListener('ReceiveMessage', (user, message) => {
  console.log(`Received message from ${user}: ${message}`);
  // 在这里处理接收到的消息
}));

4. 创建一个Redux action来发送消息：

export const sendMessage = (user, message) => {
  return (dispatch, getState) => {
    const connection = getState().signalr.connection;

    if (connection) {
      connection.invoke('SendMessage', user, message)
        .catch(error => console.error(error));
    }
  };
};

这个例子展示了如何使用AspNet Core SignalR和Redux来发送和接收数据。你可以根据自己的需求进行修改和扩展。
