"1".To<int>();
"a".To<int>(0); //转换失败返回 0
"是".To<bool>(); //支持 "是/否" "真/假" "对/错" "t/f" "true/false" 等
byte[].To<Guid>();

//进阶
"1,2,3,4,5,6".To<int[]>();
"{\"id\":\"name\":\"blqw\"}".To<User>();
Dictionary.To<Entity>(); //键值对转实体
DataRow.To<Entity>(); //数据行转实体
DataTable.To<List<Entity>>; //数据表转实体集合

//更复杂
DataTable.To<List<NameValueCollection>>(); 
List<Dictionary<string, object>>.To<DataTable>();

//变态嵌套
Dictionary<Guid, Dictionary<int, User>>
