ABP框架使用(版本3.3.1)

        public virtual async Task<Setting> FindAsync(string name, string providerName, string providerKey)
        {
            return await DbSet
                .FirstOrDefaultAsync(
                    s => s.Name == name && s.ProviderName == providerName && s.ProviderKey == providerKey
                );
        }

        public virtual async Task<List<Setting>> GetListAsync(string providerName, string providerKey)
        {
            return await DbSet
                .Where(
                    s => s.ProviderName == providerName && s.ProviderKey == providerKey
                ).ToListAsync();
        }
