请教如何提取PointRecord中的需要的字段在dataGridView表中显示，比如说我需要显示的是其中的Name+North+East+Elevation+……
简单的代码如下：
            DataSet myDataSet = new DataSet();
            myDataSet.ReadXml("20100705.xml");
            dataGridView1.DataSource = myDataSet.Tables["PointRecord"];
请高手帮忙，谢谢

Answer 1

那你只需要在gridview中设置要显示的列就可以了        <Columns>
           <asp:BoundField DataField="Name" HeaderText="名称" />
//...
        </Columns>

Answer 2

DataSet myDataSet = new DataSet();
            myDataSet.ReadXml("20100705.xml");
            //dataGridView1.DataSource = myDataSet.Tables["PointRecord"]; 注释该句            //定义需要显示的列头数组
            string[] aryColums = new string[] { "Name", "North", "East", "Elevation" };
            //定义需要显示的行数据的数组
            string[] aryData = null;
            //用数组初始化列头
            for (int i = 0; i < aryColums.Length; i++)
            {
                dataGridView1.Columns.Add(aryColums[i], aryColums[i]);
            }            //取PointRecord表数据(Name在该表中)
            DataTable t_PointRecord = myDataSet.Tables["PointRecord"];
            //取ComputedGrid表数据(Notrh,Ease,Elevation在该表中)
            DataTable t_ComputedGrid = myDataSet.Tables["ComputedGrid"];
            //定义关联ID(考虑xml中可能有多个PointRecord节点,id用于关联子节点下面的数据,即当前dataSet中表ComputedGrid的数据)
            string id = "";            //清空dataGridView
            dataGridView1.Rows.Clear();            //xml中有多少个PointRecord节点,PointRecord表中就有多少条数据,以PointRecord_Id标识唯一性
            for (int i = 0; i < t_PointRecord.Rows.Count; i++)
            {                //创建行数据数组(上面只是定义,这里才new)
                aryData = new string[aryColums.Length];
                //获取到PointRecord_Id值,用于查询ComputedGrid表数据
                id = t_PointRecord.Rows[i]["PointRecord_Id"].ToString();
                //从PointRecord表中取Name
                //注意aryData数组中值的顺序,该顺序为显示顺序
                aryData[0] = t_PointRecord.Rows[i]["Name"].ToString();
                //从ComputedGrid表中取North
                //首先查询PointRecord_Id = id 的记录,Select方法返回的是行的数组,因为满足条件的行可能存在多行
                //但就我们的情况,PointRecord节点下面有且只有一个ComputedGrid节点,所以直接取数组最上面一维,即[0]
                //取到行对象后,再使用Row[列名]取值,再ToString后存放到aryData数组中
                aryData[1] = t_ComputedGrid.Select("PointRecord_Id = '" + id + "'")[0]["North"].ToString();
                //从ComputedGrid表中取East
                aryData[2] = t_ComputedGrid.Select("PointRecord_Id = '" + id + "'")[0]["East"].ToString();
                //从ComputedGrid表中取Elevation
                aryData[3] = t_ComputedGrid.Select("PointRecord_Id = '" + id + "'")[0]["Elevation"].ToString();
                //使用aryData构到Row对象并添加到dataGridView中
                dataGridView1.Rows.Add(aryData);
}这里面只有一个PointRecord根节点时是没有问题的，但是有多个的时候就出错了
