C# 将nlog添加到.net core 3.0

将nlog添加到.net core 3.0应用程序会导致

“IServiceCollection”不包含的定义 “ConfigureLoggerService”且没有可访问的扩展方法 “ConfigureLoggerService”接受类型为的第一个参数 如果缺少using指令，则无法找到“IServiceCollection” 还是程序集引用

为了努吉，我有

NLog.Extensions.Logging v1.6.1
NLog.Web.AspNetCore v4.9.0

在startup.cs中

 public Startup(IConfiguration config)
        {
            LogManager.LoadConfiguration(String.Concat(Directory.GetCurrentDirectory(), "/nlog.config"));
            Configuration = config;
        }

public void ConfigureServices(IServiceCollection services)
        {
            services.AddAuthentication(IISDefaults.AuthenticationScheme);
            services.AddMvc();
            services.AddTransient<ICwopaAgencyFileRepository, CwopaAgencyFileRepository>();
            services.AddTransient<ICurrentUserRepository, CurrentUserRepository>();
            services.AddTransient<IUserRepository, UserRepository>();
            services.AddTransient<IRevenueReceivedRepository, RevenueReceivedRepository>();
            services.AddTransient<ILesseeRepository, LesseeRepository>();
            services.AddTransient<ITractLesseeJunctionRepository, TractLesseeJunctionRepository>();
            services.AddTransient<IPadRepository, PadRepository>();
            services.AddTransient<IWellRepository, WellRepository>();
            services.AddTransient<IWellOperarationRepository, WellOperationRepository>();
            services.AddTransient<IRoyaltyRepository, RoyaltyRepository>();
            services.AddTransient<IRoyaltyAdjustmentCardViewModelRepository, RoyaltyAdjustmentCardViewModelRepository>();
            services.AddSingleton<ILoggerManager, LoggerService>();
            string conString = Configuration["ConnectionStrings:DefaultConnection"];
            services.AddDbContext<DataContext>(options =>
                options.UseSqlServer(conString));
            services.ConfigureLoggerService();
            services.AddMvc(option => option.EnableEndpointRouting = false);
            services.AddMemoryCache();
            services.AddSession();
        }

如果您遵循这一点，请不要忘记添加此方法扩展

public static void ConfigureLoggerService(this IServiceCollection services)
{
    services.AddSingleton<ILoggerManager, LoggerManager>();
}

另外，您可以考虑删除它，因为您正在向接口ILoggerManager注册此服务LoggerService。

是否包含正确的名称空间？是否有主NLog包？它是NLog.Extensions.Logging的一部分，但他们的说明是关于NLog包的。请共享您的csproj文件刚安装了它，但它没有帮助我包括我的csproj文件配置LoggerService不是NLog提供的方法。认为你使用的是一些破损的教程。试试看这里：您是否包含了正确的名称空间？是否有一个主NLog包？它是NLog.Extensions.Logging的一部分，但他们的说明是关于NLog包的。请共享您的csproj文件刚安装了它，但它没有帮助我包括我的csproj文件配置LoggerService不是NLog提供的方法。认为你使用的是一些破损的教程。改为试试看这里：我删除了it服务。ConfigureLoggerServices，它记录得很好。谢谢。我删除了it services.ConfigureLoggerServices，它记录的很好。谢谢
