获取 DataRow 对象的数组。

重载列表 名称                    说明 Select()               获取所有 DataRow 对象的数组。 Select(String)                                   按照主键顺序（如果没有主键，则按照添加顺序）获取与筛选条件相匹配的所有 DataRow 对象的数组。   Select(String,String)                                                                        获取按照指定的排序顺序且与筛选条件相匹配的所有 DataRow 对象的数组。 Select(String,String,DataViewRowState)                               获取与排序顺序中的筛选器以及指定的状态相匹配的所有 DataRow 对象的数组。

示例：

GetRows(){        DataTable table = DataSet1.Tables[];    DataRow[] rows = table.Select();    e column of each DataRow.    ( i = 0; i < rows.Length ; i++)    {        Console.WriteLine(rows[i][]);    }}

  GetRowsByFilter(){    DataTable table = DataSet1.Tables[];        string expression;    expression =  #1/1/00#";    DataRow[] foundRows;        foundRows = table.Select(expression);        ( i = 0; i < foundRows.Length; i ++)    {        Console.WriteLine(foundRows[i][0]);    }}

GetRowsByFilter(){    DataTable table = DataSet1.Tables[];        string expression = '1/1/00'";        string sortOrder = ;    DataRow[] foundRows;        foundRows = table.Select(expression,sortOrder);        ( i = 0; i < foundRows.Length; i ++)    {        Console.WriteLine(foundRows[i][0]);    }}
