如何启用DbCommand原始SQL查询的日志记录？

How do I enable the logging of DbCommand raw SQL queries?

我已将以下代码添加到Startup.cs文件中，但是看不到任何日志条目

I have added the following code to my Startup.cs file, but do not see any log entries from the Entity Framework Core.

void ConfigureServices(IServiceCollection services) { services.AddLogging(); } public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddConsole(Configuration.GetSection("Logging")); loggerFactory.AddDebug(LogLevel.Debug); }

我希望看到这样的东西：

I'm expecting to see something like this:

Microsoft.EntityFrameworkCore.Storage.Internal.RelationalCommandBuilder... SELECT [t].[Id], [t].[DateCreated], [t].[Name], [t].[UserName] FROM [Trips] AS [t]

推荐答案

想通了-需要配置DbContext才能使用记录器工厂。

Figured it out - need to configure DbContext to use logger factory.

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) { base.OnConfiguring(optionsBuilder); optionsBuilder.UseLoggerFactory(_loggerFactory); }
