.Net Core 2.1 升級3.1 問題整理
阿新 • • 發佈：2021-03-12
隨著技術的不斷拓展更新，我們所使用的技術也在不斷地升級優化，專案的框架也在不斷地升級，本次講解 .net core 2.1 升級到3.1所需要注意的事項；
當專案框架升級後，所有的Nuget引用也會對應變化，這些根據自己的框架所使用的技術對應做升級即可，這裡不做過多贅述；
其次就是要修改 Program.cs 檔案，這裡把修改前的和修改後的統一貼出程式碼做調整，程式碼如下：
2.1版本的檔案程式碼：
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using System;
namespace S2_Xxxx_XxxNetApi
{
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
Console.WriteLine("介面啟動成功");
// QuartzHelper.ExecuteInterval<Test>(200);
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
//.UseUrls("http://*:5000")//釋出時需要註釋
.UseStartup<Startup>();
}
}3.1版本的檔案程式碼
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;
using System;
namespace S2_Cggc_PmsNetApi
{
/// <summary>
/// 啟動
/// </summary>
public class Program
{
/// <summary>
/// 啟動
/// </summary>
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
Console.WriteLine("介面啟動成功");
}
/// <summary>
/// 啟動
/// </summary>
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
}
}然後就是Startup檔案，程式碼如下：

public void ConfigureServices(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
//排程任務註冊
services.AddSingleton<ISchedulerFactory, StdSchedulerFactory>();//註冊ISchedulerFactory的例項。
string conn = Configuration.GetSection("AppSettings:ConnectString").Value;
MySqlHelper.Conn = conn;
string orclconn = Configuration.GetSection("AppSettings:OrclConnectString").Value;
OracleHelper.connectionString = orclconn;
string redisconn = Configuration.GetSection("AppSettings:RedisConnectString").Value;
RedisHelper.SetCon(redisconn);
RedisHelper.BuildCache();
services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

options.Cookie.HttpOnly = true;//設定在瀏覽器不能通過js獲得該cookie的值
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddSingleton<IActionContextAccessor, ActionContextAccessor>();
services.AddSwaggerGen(options =>
{
options.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info

Version = "v1",
Title = "介面文件"
});
options.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
});
}

app.UseMvc(routes =>

做了對應調整後，編譯後檢查是否還有錯誤提示，即可升級成功，可能有些控制器裡面的屬性寫法也會有些變化，這個還沒有具體深入研究，歡迎小夥伴們做補充，我將虛心接受大家的意見，感謝~
