然后可以看到这个set中的数据应该是这样的：上图是在VS中的调试模式中，可以看到 根据上图我们大概可以猜测一下DataTable内部的数据结构，或者C#让我们理解的结构是什么。其中DataColumn对应着图中列，ColumnName就是图 所示的列名。而DataRow就是行，ItemArray则是一行行数据。这样一来，显然就比直接使用IDataReader访问...

点阵列(BitArray)1. 简介BitArray 类管理一个紧凑型的位值数组,它使用布尔值来表示,其中 true 表示位是开启的(1),false 表示位是关闭的(0)。 当您需要存储位,但是事先不知道位数时,则使用点阵列。您可以使用整型索引从点阵列集合中访问各项,索引从零开始。2. 特性介绍1)BitArray 的… ...
