billyang / surgingdemo Goto Github PK

之前能dotnet run 正常运行
今天无修改，dotnet run 报了以下错误
Program.cs(19,21): error CS0017: 程序定义了多个入口点。使用 /main (指定包含入口点的类型)进行编译。 [f:\dotnet\SurgingDemo\src\Bill.Demo.Solutions\Bill.Demo.Services.Server\Bill.Demo.Services.Server.csproj]

有遇到过吗

具体信息:

surging用的V1.0,运行服务有代理找不到的bug,还有demo里的修改\新增\删除事件会执行两次..请问有码友知道怎么回事吗?

这个demo跑不起来的，请看这里https://github.com/zhuzhao/SurgingDemoUpdate

运行Bill.Demo.Services.Server时，在ServiceHostBuilderExtensions.UseLog4net报错：
Value cannot be null.
Parameter name: config
at Microsoft.Extensions.Options.ConfigurationChangeTokenSource1..ctor(String name, IConfiguration config) at Microsoft.Extensions.Logging.LoggingBuilderExtensions.AddConfiguration(ILoggingBuilder builder, IConfiguration configuration) at Surging.Core.Log4net.ServiceHostBuilderExtensions.<>c.<UseLog4net>b__0_0(ILoggingBuilder logger) in D:\microservice\surging\src\Surging.Core\Surging.Core.Log4net\ServiceHostBuilderExtensions.cs:line 15 at Microsoft.Extensions.DependencyInjection.LoggingServiceCollectionExtensions.AddLogging(IServiceCollection services, Action1 configure)

at Bill.Demo.Services.Server.Program.Main(String[] args) in D:\microservice\SurgingDemo\src\Bill.Demo.Solutions\Bill.Demo.Services.Server\Program.cs:line 24

我发现这个问题是在host.Build()的时候调用了
})
.UseStartup()
.Build();

        using (host.Run())
        {
            Console.WriteLine($"服务端启动成功，{DateTime.Now}。");
        }

但是这个Configuration是在host.Run()初始化的。
而host.Run()在Build()后执行，所以报了个null的错误。

作者方便解答下这个该怎么解决吗？

Unhandled Exception: System.ArgumentNullException: Value cannot be null. Parameter name: config at Microsoft.Extensions.Options.ConfigurationChangeTokenSource1..ctor(String name, IConfiguration config)
at Microsoft.Extensions.Logging.LoggingBuilderExtensions.AddConfiguration(ILoggingBuilder builder, IConfiguration configuration)`

调试的时候，发现是UseLog4net("Configs/log4net.config")报出来的。
跟进去，发现是CPlatform.AppConfig中的Configuration为null，导致CPlatform.AppConfig.GetSection("Logging")为null。

请问，这个问题是如何解决的呢？
我是使用了最新版本的Surging.
