ExecuteQuery主要用于DataContext类直接执行SQL语句的查询，在MSDN上有两种执行方法，下面为两种方法的不同调用：
1、ExecuteQuery<TResult>(String, Object[]) 应该是微软的推荐方法，网上几乎都在用的方法
NorthwindDataContext ctx = new NorthwindDataContext("server=xxx;database=Northwind;uid=xxx;pwd=xxx"); string newcity = "Shanghai"; ctx.ExecuteCommand("update Customers set City={0} where CustomerID like ‘A%‘", newcity); IEnumerable<Customer> customers = ctx.ExecuteQuery<Customer>("select * from Customers where CustomerID like ‘A%‘"); GridView1.DataSource = customers; GridView1.DataBind();
2、ExecuteQuery(Type, String, Object[]) Type为要返回的 IEnumerable<T> 的类型。
DataContext db = new DataContext("Data Source=*******;Initial Catalog=*****;Persist Security Info=True;User ID=sa;Password=*****"); StreamWriter sw = new StreamWriter(Server.MapPath("log.txt"), true); //db.Log = sw; Table<NewsList> news = db.GetTable<NewsList>(); var select = from p in news select new { 标题 = p.title }; IDbCommand cmd = db.GetCommand(select); var newss = db.ExecuteQuery(typeof(NewsList), "SELECT NewsID,TITLE FROM lmh_Newslist"); foreach (var s in newss) { NewsList s1 = (NewsList)s; //Response.Write(s1.title); }
