dataset固定取值

Question

写了个xml
<?xml version="1.0" encoding="utf-8" ?>
<UTClist>
    <utc>
        <name>erp</name>
        <value>+8</value>
    </utc>
    <utc>
        <name>homelava</name>
        <value>-5</value>
    </utc>
</UTClist>
读取
DataSet xmlDataSet = new DataSet();
xmlDataSet.ReadXml(Server.MapPath("UTC.xml"));
DataTable utc_dt = xmlDataSet.Tables[0];怎么样动态根据name值获取对应的value值
例如我知道name=erp 怎么样获取到value=+8值

Answer 1

 DataSet xmlDataSet = new DataSet();
 xmlDataSet.ReadXml("2.xml");
 DataTable utc_dt = xmlDataSet.Tables[0];
 var key = utc_dt.Select("name='erp'").FirstOrDefault()["value"].ToString();
 Console.WriteLine(key);
 Console.Read();
