C# 依赖注入 注入泛型

代码示例

public interface IMalemaLogger<T>
{
}

public class MalemaLogger<T> : IMalemaLogger<T>
{
    private ILogger logger { get; set; }

    public MalemaLogger(ILoggerFactory loggerFactory)
    {
        // 在这边可以得到T的类型
        var name = "malema." + typeof(T).Name;
        this.logger = loggerFactory.CreateLogger(name);
    }
}

//注入的时候得用这个方式。
services.AddScoped(typeof(IMalemaLogger<>), typeof(MalemaLogger<>));

//使用它的地方
public class Worker
{
    private readonly IMessageWriter _messageWriter;
    private readonly Func<MalemaDbContext> _func;
    private readonly IMalemaLogger<Worker> _malemaLogger;

    public Worker(IMessageWriter messageWriter,
        Func<MalemaDbContext> func,
        IMalemaLogger<Worker> malemaLogger) //注入了
    {
        _messageWriter = messageWriter;
        _func = func;
        _malemaLogger = malemaLogger;
    }
}
