js获取当前时间

var d = new Date()

var nowYear = +d.getFullYear()

 EF框架填充下拉菜单 var model = db.GYSAllFoods.Select(m => new{GYS = m.GYS}).Distinct();//去重很关键
            foreach (var item in model)
            {
                comboBoxGYSName.Items.Add(item.GYS);
                comboBoxGYSName.SelectedIndex = 0;
            }

 EF框架将数据库数据填充datagridview var GYSlist = db.GYSAllFoods.Select(m => m);
            GYSlist = GYSlist.Where(m => m.GYS.IndexOf(strGYS) >= 0);
            var Item = GYSlist.ToList();
            dataGridViewGYS.DataSource = Item;
            dataGridViewGYS.Columns[1].DataPropertyName = "GYSFoodName";
