IHostEnvironment获取程序信息

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

app.Run(async (context) =>
{
await context.Response.WriteAsync($"ApplicationName:{env.ApplicationName}");
await context.Response.WriteAsync($"ContentRootPath:{env.ContentRootPath}");
await context.Response.WriteAsync($"WebRootPath:{env.WebRootPath}");
await context.Response.WriteAsync($"是否开发环境:{env.IsDevelopment()}");
});
}

IApplicationLifetime站点启动或关闭时的监控

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IApplicationLifetime applicationLifetime)
{
applicationLifetime.ApplicationStarted.Register(() =>
{
Console.WriteLine("ApplicationStarted");
});
applicationLifetime.ApplicationStopped.Register(() =>
