我有一个数据集,我通过Oracle SQL查询填充:
SELECT col_id, col_desc
FROM table_data;
然后我通过函数
生成数据集Dim ds as New DataSet
OracleDataAdapter.Fill(ds)
现在,当我通过以下方式获取生成的数据集的XML时
Dim strXML as String
strXML = ds.GetXML()
当我读取/显示字符串时,它显示如下:
<NewDataSet>
<Table>
<COL_ID>ABC001</COL_ID>
<COL_DESC>Angelo</COL_DESC>
</Table>
<Table>
<COL_ID>ZFE851</COL_ID>
<COL_DESC>John</COL_DESC>
</Table>
<Table>
<COL_ID>XYU123</COL_ID>
<COL_DESC>Mary</COL_DESC>
</Table>
<Table>
<COL_ID>MLP874</COL_ID>
<COL_DESC>James</COL_DESC>
</Table>
</NewDataSet>
我想要的是结果字符串应该显示如下:
<NewDataSet>
<Table COL_ID="ABC001" COL_DESC="Angelo"></Table>
<Table COL_ID="ZFE851" COL_DESC="John"></Table>
<Table COL_ID="XYU123" COL_DESC="Mary"></Table>
<Table COL_ID="MLP874" COL_DESC="James"></Table>
</NewDataSet>
我怎样才能做到这一点?
如果说,我会从数据集中的表中读取行并构造字符串吗?

在获取XML之前将DataColumn.MappingType设置为MappingType.Attribute:
Dim column As DataColumn
For Each column In ds.Tables.Item(0).Columns
column.ColumnMapping = MappingType.Attribute
Next
ds.GetXml()
