Csharp 如何创建可以使用任何 Ef Core DbContext 的类库

可以在方法上使用where条件.

public class TranslateManager : ITranslateManager
{
    private readonly ContextDb _contextDb;

    public TranslateManager(ContextDb contextDb)
    {
        _contextDb = contextDb;
    }

    public async Task CreateTranslationAsync<T>(long langId) where T : class, ITranslate
    {
        // ToDo
    }

    public async Task<ITranslate> GetBestTranslationAsync<T>(long langId) where T : class, ITranslate
    {
        var dbSet = _contextDb.GetDbSet<T>();
        return await dbSet.Where(x => x.LangId == langId).FirstOrDefaultAsync();
    }
}

public interface ITranslate
{
    public long Id { get; set; }
    public long ParentId { get; set; }
    public long LangId { get; set; }
}

public partial class SectionTranslation : ITranslate
{
    public long Id { get; set; }
    public long ParentId { get; set; }
    public long LangId { get; set; }
    public string SectionName { get; set; }
}

public partial class TemplateTranslation : ITranslate
{
    public long Id { get; set; }
    public long ParentId { get; set; }
    public long LangId { get; set; }
    public string TemplateName { get; set; }
}

public interface ITranslateManager
{
    Task<T> GetBestTranslationAsync<T>(long langId) where T : class, ITranslate;
    Task CreateTranslationAsync<T>(long langId) where T : class, ITranslate;
}
