一、cba赛程
C#是微软公司推出的一种针对Windows平台的高级编程语言。而C#对于很多开发者来说，就像NBA对于球迷一样，是一种热爱和追求。在C#的社区中，类似NBA赛程一样的热门话题，就是cba赛程。这里我们将以使用C#实现获取最新cba赛程为例，详细阐述C#的WEB服务。 首先我们需要创建一个ASP.NET WEB服务项目，然后在代码中使用HttpClient进行cba网站的数据请求，获取json格式的数据后进行反序列化，最终获取最新的cba赛程。以下是相关代码实现：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web;
using System.Web.Services;
using Newtonsoft.Json;
namespace CBAWebService
{
/// <summary>
/// 获取cba赛程的WEB服务
/// </summary>
[WebService(Namespace = "http://cba.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class CBASchedule : WebService
{
[WebMethod]
public string GetSchedule()
{
using (var httpClient = new HttpClient())
{
var result = httpClient.GetAsync("http://cba.sports.sina.com.cn/cba/schedule/index.json").Result;
var json = result.Content.ReadAsStringAsync().Result;
var schedule = JsonConvert.DeserializeObject<List<Schedule>>("[" + json + "]");
var latestSchedule = schedule.OrderByDescending(s => s.date).ThenByDescending(s => s.id).First();
return JsonConvert.SerializeObject(latestSchedule, Formatting.None);
}
}
}
public class Schedule
{
public string date { get; set; }
public string time { get; set; }
public string leftTeam { get; set; }
public string rightTeam { get; set; }
public string url { get; set; }
public int id { get; set; }
}
}
二、coach
使用C#开发一个教练管理系统，可以让我们更好地了解C#的面向对象思想和语法知识。下面是一个简单的代码实例展示如何创建一个Coach类：
public class Coach
{
private string name;
private int age;
private string teamName;
public Coach(string name, int age, string teamName)
{
this.name = name;
this.age = age;
this.teamName = teamName;
}
public string GetName()
{
return this.name;
}
public void SetName(string name)
{
this.name = name;
}
public int GetAge()
{
return this.age;
}
public void SetAge(int age)
{
this.age = age;
}
public string GetTeamName()
{
return this.teamName;
}
public void SetTeamName(string teamName)
{
this.teamName = teamName;
}
}
三、cctv5节目表
C#可以用来开发跨平台的移动应用程序。在移动应用的开发中，往往需要使用到网络请求和数据解析，以下是在C#移动应用中获取cctv5节目表的相关代码：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
GetCctv5ProgramTable();
}
private async void GetCctv5ProgramTable()
{
var client = new HttpClient();
var response = await client.GetAsync("http://api.cntv.cn/epg/getEpgInfoByChannelNew?c=china&d=20210822&p=1&v=4&cb=epgnew&_=" + GetTimeStamp().ToString());
var result = await response.Content.ReadAsStringAsync();
// 省略解析json，更新UI的部分代码
}
private int GetTimeStamp()
{
return Convert.ToInt32(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
}
}
四、chat GPT人工智能
使用C#开发聊天机器人的应用程序是一个不错的练手项目，下面我们展示的是如何把GPT人工智能集成到C#聊天机器人中：
public class Gpt2Bot
{
private DefaultHttpClient httpClient = new DefaultHttpClient();
public async Task<string> GetResponse(string query)
{
var json = JsonConvert.SerializeObject(new { textInput = query });
var httpRequestMessage = new HttpRequestMessage
{
Method = HttpMethod.Post,
RequestUri = new Uri("https://api.ai21.com/gpt2?max_tokens=64&temperature=0.7"),
Headers =
{
{ HttpRequestHeader.ContentType.ToString(), "application/json; charset=utf-8" },
{ "Authorization", "Bearer " + GetAuthToken() }
},
Content = new StringContent(json, Encoding.UTF8, "application/json")
};
var httpResponseMessage = await httpClient.SendAsync(httpRequestMessage).ConfigureAwait(false);
httpResponseMessage.EnsureSuccessStatusCode();
var responseBody = await httpResponseMessage.Content.ReadAsStringAsync().ConfigureAwait(false);
var responseJson = JsonConvert.DeserializeObject(responseBody);
return ExtractTextFromJson(responseJson);
}
private string ExtractTextFromJson(dynamic responseJson)
{
// 省略解析json
}
private string GetAuthToken()
{
// 省略获取token的部分代码
}
}
五、cctv5在线直播
C#可以用于开发桌面应用程序，比如视频播放器。以下是一个简单的代码实现展示如何使用C#实现cctv5直播：
public partial class MainForm : Form
{
private HttpServer _localServer;
private Process _vlcPlayerProcess;
public MainForm()
{
InitializeComponent();
}
private void MainForm_Load(object sender, EventArgs e)
{
var m3u8Url = "http://lives.cctv.com/1001.m3u8";
var vlcPlayerPath = @"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe";
if (!File.Exists(vlcPlayerPath))
{
MessageBox.Show("请先安装VLC播放器");
return;
}
try
{
_localServer = new HttpServer(m3u8Url);
var localUrl = "http://localhost:" + _localServer.Port.ToString() + "/";
_vlcPlayerProcess = Process.Start(vlcPlayerPath, localUrl);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
{
_localServer?.Dispose();
_vlcPlayerProcess?.Kill();
}
}
public class HttpServer : IDisposable
{
private readonly HttpListener _listener;
private readonly string _url;
private readonly byte[] _buffer = new byte[0x10000];
private Task _acceptTask;
public int Port { get; }
public HttpServer(string url)
{
_url = url;
_listener = new HttpListener();
_listener.Prefixes.Add(url);
_listener.Start();
Port = new Uri(url).Port;
_acceptTask = Task.Factory.StartNew(AcceptConnections, this, TaskCreationOptions.LongRunning);
}
private async Task AcceptConnections()
{
while (_listener.IsListening)
{
try
{
var context = await _listener.GetContextAsync();
var buffering = context.Response.SendChunked;
var requestUrl = context.Request.RawUrl;
using (var client = new HttpClient())
{
var response = await client.GetAsync(requestUrl);
var content = await response.Content.ReadAsByteArrayAsync();
context.Response.ContentLength64 = content.Length;
await context.Response.OutputStream.WriteAsync(content, 0, content.Length);
}
}
catch (HttpListenerException) { }
catch (ObjectDisposedException) { }
}
}
public void Dispose()
{
_listener?.Stop();
_listener?.Close();
_acceptTask?.Dispose();
}
}
六、c1驾照能开什么车

public Question()
{
_connectionString = ConfigurationManager.ConnectionStrings["QuestionDB"].ConnectionString;
_conn = new MySqlConnection(_connectionString);
}
public void Insert()
{
_conn.Open();
var insertCommand = new MySqlCommand
{
Connection = _conn,
CommandText = "INSERT INTO question (title, option_a, option_b, option_c, option_d, answer, analysis, type) " +
"VALUES (@title, @optionA, @optionB, @optionC, @optionD, @answer, @analysis, @type);"
};
insertCommand.Parameters.AddWithValue("@title", Title);
insertCommand.Parameters.AddWithValue("@optionA", OptionA);
insertCommand.Parameters.AddWithValue("@optionB", OptionB);
insertCommand.Parameters.AddWithValue("@optionC", OptionC);
insertCommand.Parameters.AddWithValue("@optionD", OptionD);
insertCommand.Parameters.AddWithValue("@answer", Answer);

question.Answer = reader.GetString("answer");
question.Analysis = reader.GetString("analysis");
question.Type = reader.GetInt32("type");
}
reader.Close();
_conn.Close();
return question;
}
}
七、c反应蛋白高说明什么
在健康检查中，如果我们的c反应蛋白高了，就说明可能存在炎症、感染等相关问题。使用C#可以开发健康管理应用程序，将c反应蛋白高值输入进去，给出相应的健康分析报告。以下是相关代码展示：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnAnalysis_Click(object sender, EventArgs e)
{
var crpValue = Convert.ToDouble(tbxCRPValue.Text);
var healthReport = GetHealthAnalysisReport(crpValue);
lblOverallHealth.Text = healthReport.OverallHealth;
lblInflammationRisk.Text = healthReport.InflammationRisk;
lblPossibleDiseases.Text = healthReport.PossibleDiseases;
}
private HealthAnalysisReport GetHealthAnalysisReport(double crpValue)
{
if (crpValue < 1.0)
{
return new HealthAnalysisReport("健康", "低", "无");
}
else if (crpValue <= 3.0)
{
return new HealthAnalysisReport("中等", "中等", "感染风险、炎症风险");
}
else
{
return new HealthAnalysisReport("健康风险", "高", "感染、肿瘤等慢性发病风险");
}
}
}
public class HealthAnalysisReport
{
public string OverallHealth { get; }
public string InflammationRisk { get; }
public string PossibleDiseases { get; }
public HealthAnalysisReport(string overallHealth, string inflammationRisk, string possibleDiseases)
{
OverallHealth = overallHealth;
InflammationRisk = inflammationRisk;
PossibleDiseases = possibleDiseases;
}
}
