C#如何獲取xml數據並轉換為dataset

//獲取xml數據，並轉換為dataset  
public static DataSet getConfig(string strXmlPath)  
{  
    string filePath = GetPhysicalPath();  
    DataSet ds= ConvertXMLFileToDataSet(GetXmlFullPath(filePath));  
    return ds;  
}  
 //將xml文件轉換為DataSet  
public static DataSet ConvertXMLFileToDataSet(string xmlFile)  
{  
    StringReader stream = null;  
    XmlTextReader reader = null;  
    try
    {  
        XmlDocument xmld = new XmlDocument();  
        xmld.Load(xmlFile);  
        DataSet xmlDS = new DataSet();  
        stream = new StringReader(xmld.InnerXml);  
        //從stream裝載到XmlTextReader  
        reader = new XmlTextReader(stream);  
        xmlDS.ReadXml(reader);  
        //xmlDS.ReadXml(xmlFile);  
        return xmlDS;  
    }  
    catch (System.Exception ex)  
    {  
        throw ex;  
    }  
    finally  
    {  
        if (reader != null)  
         reader.Close();  
    }  
}
