这个对象里面收集了一个表的数据库表名称、数据库表ID、数据库表类型、数据库表描述、数据库表创建日期等信息。
我们可以建立一个泛型集合来存储表对象。
using System;
using System.Collections.Generic;
/// <summary>
/// 存储数据库表信息的集合
/// </summary>
/// <author>天志</author>
/// <log date="2007-09-01">创建</log>
public class TableList<T> : List<T> where T : TableDT
{
public TableList() : base()
{
}
public TableList(IEnumerable<T> collection)
: base(collection)
{
}
public TableList(int capacity)
: base(capacity)
{
}
}
using System.Collections.Generic;
/// <summary>
/// 存储数据库表信息的集合
/// </summary>
/// <author>天志</author>
/// <log date="2007-09-01">创建</log>
public class TableList<T> : List<T> where T : TableDT
{
public TableList() : base()
{
}
public TableList(IEnumerable<T> collection)
: base(collection)
{
}
public TableList(int capacity)
: base(capacity)
{
}
}
表对象的结构要比列结构要简单,但是我们可以对表对象进行扩展。扩展的信息可以包括:表包含的列信息、当前表的主键信息,当前表的外键信息,当前表被哪些表当成外键表,当前表的标识字段是哪个,当前表的主键字段都有哪一些。
