MDataTable 原理解析 数据行

有了数据结构单元DataCell之后，数据单元行也就很容易写了，因为，所有的数据单元加起来，就成了数据行了
于是，我们很轻易的写出了以下类:   Code/**//// <summary> /// 一行数据 /// </summary> public class MDataRow : List<MDataCell>  { public MDataRow() : base()  { } public MDataRow(int capacity) : base(capacity) { } }
看，没几行代码 现在，我们为行加几个常用的属性,比如访问行所属的表名，还有从行访问出其列的结构，顺便加上一个数据库链接字符串
如下: Code常用访问属性#region 常用访问属性 private string _TableName; /**//// <summary> /// 数据库表名 /// </summary> public string TableName { get { return _TableName; } set { _TableName = value; } } private string _ConnectionString; /**//// <summary> /// 所属的表的数据库链接字符串 /// </summary> public string ConnectionString { get { return _ConnectionString; } set { _ConnectionString = value; } } private MDataColumn _Columns = null; /**//// <summary> /// 数据列集合 /// </summary> public MDataColumn Columns { get { if (_Columns == null) { _Columns = new MDataColumn(base.Count); for (int i = 0; i < base.Count; i++) { _Columns.Add(base[i].DataStruct); } } return _Columns; } } #endregion
OK,此至属性也加完了，顺便加个克隆方法 Code克隆#region 克隆 public MDataRow Clone() { MDataRow dataRow = new MDataRow(base.Count); for (int i = 0; i < base.Count; i++) { MDataCellStruct mcb = base[i].DataStruct; MDataCell mdc = new MDataCell(ref mcb); mdc.Value = base[i].Value; dataRow.Add(mdc); } dataRow.ConnectionString = this.ConnectionString; dataRow.TableName = this.TableName; return dataRow; } #endregion至此，数据行也构建完成了
