.net 匿名方法

匿名方法

核心就是lambda语法，下面是使用举例：

var conn= MySqlHelper.GetConn(); ???????????var list=conn.Query<User>("SELECT Account FROM `QQ_User` ").ToArray(); ???????????list.OrderBy(p => p.Account); ???????????list.OrderByDescending(p => p.Account); ???????????list.Where(p => ?p.Account == "10001");-----返回的是数组，及时没有找到符合条件的p,也是返回的空数组。可以用.count来判断是否取到了需要的值 ???????????list.FirstOrDefault(p => p.Account == "10001"); ???????????list.Select(p => p.Account); ???????????//public static IEnumerable<TResult> Select<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, TResult> selector); ???????????var temp = list.Select(p => new Temp() { QQNumber = p.Account }); ???????????list.Count(p => p.Account == "10001"); ???????????list.Where(p => p.Age > 20).OrderBy(p => p.Age).Skip(49).Take(50);list.alllist.any
