自定义Serilog接收器无法使用AppSettings

我正在尝试为Serilog设置自定义接收器,但无法使其正常工作..

我正在使用Logger:

Log.Logger = new LoggerConfiguration().ReadFrom.AppSettings().CreateLogger();

如果我这样做,它确实有效:

//Log.Logger = new LoggerConfiguration().WriteTo.LogSenderSink().CreateLogger();

所以它只在使用AppSettings时才能正确触发。

我有两个类,一个用于接收器,另一个用于扩展。

水槽:

using System;
using Serilog.Core;
using Serilog.Events;

namespace Serilog.Sinks.LogSender
{
    public class LogSenderSink : ILogEventSink, IDisposable
    {
        private readonly IFormatProvider _formatProvider;

        public LogSenderSink(IFormatProvider formatProvider, LogEventLevel restrictedToMinimumLevel)
        {
            _formatProvider = formatProvider;
        }

        public void Dispose()
        {

        }

        public void Emit(LogEvent logEvent)
        {
            var message = logEvent.RenderMessage(_formatProvider);
            Console.WriteLine(DateTimeOffset.Now.ToString() + " " + message);

            try
            {
                System.IO.File.WriteAllText(@"C:\Logs\test.txt", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
            }
            catch { }
        }
    }
}

扩展方法:

using Serilog.Configuration;
using Serilog.Events;
using Serilog.Sinks.LogSender;
using System;

namespace Serilog
{
    public static class LogSinkExtensions
    {
        public static LoggerConfiguration LogSenderSink(
                this LoggerSinkConfiguration loggerConfiguration,
                LogEventLevel restrictedToMinimumLevel = LevelAlias.Minimum,
                  IFormatProvider formatProvider = null)
        {
            return loggerConfiguration.Sink(new LogSenderSink(formatProvider, restrictedToMinimumLevel));
        }
    }
}

我测试的项目中的我的App.config看起来像这样:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
  <appSettings>
    <add key="serilog:minimum-level" value="Verbose"/>

    <add key="serilog:using:LogSender" value="Serilog.Sinks.LogSender" />
  </appSettings>
</configuration>

我在这里缺少什么?

我正在调用这样的日志:

Log.Information("Debug was just sent");

根本没有任何事情发生......

谢谢你的时间!

您是否错过了配置文件中的serilog:write-to:LogSenderSink设置?

请查看https://github.com/FantasticFiasco/serilog-sinks-http-sample-dotnet-framework/blob/master/sample/App.config。它是使用app配置与Serilog结合的示例的一部分。
