MDataTable 原理解析 数据表

| #TopicOwner |
自从构成最小单元数据单元之后，之后的行与列头的类，都变的很容易写 表也是一样，所有行的集合，即为表，于是，我们也很容易写出表类 如下：   Code public class MDataTable : List<MDataRow>  { private string _TableName =string.Empty;  /**//// /// 表名 /// public string TableName { get { return _TableName; } set { _TableName = value; } } public MDataTable() { _TableName = "Default"; } public MDataTable(string tableName) { _TableName = tableName; } }这时表就基本构建好了，默认只有一个表名属性 我们再为它增加访问列头的属性
如下： Code private MDataColumn _Columns; public MDataColumn Columns { get { if (this.Count > 0) { return this[0].Columns; } if (_Columns == null) { _Columns = new MDataColumn(); } return _Columns; } }
至此，表也基本构建完成了 下一节，我们将实现让我们的自定MDataTable与我们常用的用户控件交互  | |
