As said above, if you're requesting data out of a WCF service, it will serialize to XML for you, send over the wire & your WCF client will deserialize - it's all done for you, no interaction required. 如上所述，如果您要从WCF服务中请求数据，它将为您序列化为XML，通过有线发送，并且WCF客户端将进行反序列化-一切都为您完成，不需要任何交互。
If you just want to go from data to XML, you can load your SQL reader to a DataSet, then get the XML from that dataset ( DataSet.GetXml() ) - while probably not the best/fastest way, it's quick and dirty. 如果只想从数据转换为XML，则可以将SQL阅读器加载到DataSet，然后从该数据集（ DataSet.GetXml() ）获取XML-虽然可能不是最好/最快的方法，但它又快又脏。 For a single table of data, the .net DataTable also has a WriteXml method that writes to file, stream, etc. 对于单个数据表，.net DataTable还具有WriteXml方法，该方法可写入文件，流等。
