DataTables是XML可序列化的，因此您可以将它们用作XML Web Service的输入和输出.这是MSDN上的文章使用XML Web服务中的数据集 [ ^ ]

希望对您有帮助

DataTables are XML serializable, and so you can use them as both input and output from an XML Web Service. Here is an article from MSDN Consuming a DataSet from an XML Web Service[^]

Hope this helps

您可以在WebService中返回DataTable.
您只需要提供完整的DataTable名称即可.

例如
DataTable dt =新的DataTable("YourTableName");

就这样.

要在Web服务中返回对象，Microsoft需要对对象进行序列化.
那时，您的数据表对象必须具有名称.因此，微软将像
那样转换为XML. < yourtablename>
< ------
----->
< yourtablename>
如果您的表没有名称，Microsoft将无法序列化为XML文件.因此，将引发错误.

谢谢

You can return DataTable in WebService.
You just need to give full DataTable name.

e.g
DataTable dt = new DataTable("YourTableName");

That''s all.

To return object in web service, Microsoft need to serialize the object.
At that time your data table object must has name. So, Microsoft will convert to XML like
<yourtablename>
<------
----->
<yourtablename>
If your table has no name, Microsoft cannot serialize as XML file. So, will be throw error.
