1.增

using (var bridgeContext = new BridgeContext())
{
    //新增一個物件
    T_EF t_EF = bridgeContext.T_EF.Add(new T_EF() { Name = "RB" });
    //將修改後的儲存到資料庫
    bridgeContext.SaveChanges();
}

2.刪

//刪除資料也需先查出後刪除再儲存
DbSqlQuery<T_EF> dbSqlQuery = bridgeContext.T_EF.SqlQuery("select * from [T_EF] where [ID] = {0}", 2);
bridgeContext.T_EF.RemoveRange(dbSqlQuery);
bridgeContext.SaveChanges();

3.改　

//修改資料，需先查出實體，再修改儲存
T_EF t_EF1 = bridgeContext.T_EF.Find(1);
t_EF1.Location ="GD";
bridgeContext.SaveChanges();

4.查

//根據主鍵查詢
T_EF t_EF1 = bridgeContext.T_EF.Find(1);
//根據TSQL查詢
DbSqlQuery<T_EF> dbSqlQuery = bridgeContext.T_EF.SqlQuery("select * from [T_EF] where [ID] = {0}", 2);
