Question

我有.net核心应用程序与EFCore数据库上下文：

public class MyappDbContext : DbContext
{
    private ILogger<MyappDbContext> _logger;

    public MyappDbContext(DbContextOptions<MyappDbContext> options)
        : base(options)
    {
        // ???
    }
}

在启动类中我注册了上下文：

services.AddDbContext<MyappDbContext>(options => options.UseSqlServer(connectionString));

如何注入MyappDbContext ILogger或ILoggerFactory（创建记录器）？

Answer 1

您需要做的就是在上下文构造函数中添加ILoggerFactory或ILogger参数：

public class MyappDbContext : DbContext
{
    private readonly ILogger<MyappDbContext> _logger;

    public MyappDbContext(DbContextOptions<MyappDbContext> options,
        ILogger<MyappDbContext> logger)
        : base(options)
    {
        _logger = logger;
    }
}

如何将ILogger注入EFCore DbContext
