【问题描述】:
我正在尝试构建一个作为 Windows 服务运行并能够记录到应用程序事件日志的 .NET Core WorkerService。
我没有收到任何错误或服务使用 sc create then sc start 运行的任何内容,但我在事件应用程序事件日志中没有得到任何预期。
我错过了什么?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Logging.EventLog;
namespace FreshIQPrinterProxy
{
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.UseWindowsService()
.ConfigureLogging((context, logging) =>
{
logging.AddEventLog(new EventLogSettings()
{
SourceName = "MyApp"
});
})
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
}
}
这是我的 Worker.cs 文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Logging.EventLog;
namespace FreshIQPrinterProxy
{
public class Worker : BackgroundService
{
private readonly ILogger<Worker> _logger;
public Worker(ILogger<Worker> logger)
{
_logger = logger;
}
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
while (!stoppingToken.IsCancellationRequested)
{
_logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
await Task.Delay(1000, stoppingToken);
}
}
}
}
这是我的 appsettings.json 文件
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"EventLog": {
"LogLevel": {
"Default": "Information",
"Microsoft.Hosting.Lifetime": "Information"
}
}
}
