如何读取xml文件 [英] How to read xml file

问题描述

大家好，

我正在尝试使用数据集读取xmlfile，我在这里遵循的步骤是

1.访问数据库并获取数据表
2.将数据表转换为xmldoucment
3.在这里，我喜欢使用数据集阅读转换后的xmldocument
为此，我在
中尝试了

Hi all,

i am trying to read the xmlfile using data set the steps i followed here are

1. accessing the database and getting the datatable
2. converting datatable into xmldoucment
3. here i like read the converted xmldocument using dataset
for this i tried in

dim ds as dataset
ds.readXml(xmldocument)

但我在这里遇到错误...


错误1重载解析失败，因为无法使用以下参数调用可访问的"ReadXml":
``公共功能ReadXml(文件名作为字符串)作为System.Data.XmlReadMode'':类型``System.Xml.XmlDocument''的值不能转换为``String''.
``公共功能ReadXml(阅读器作为System.IO.TextReader)作为System.Data.XmlReadMode'':不能将类型为``System.Xml.XmlDocument''的值转换为``System.IO.TextReader''. br/> ``公共功能ReadXml(流作为System.IO.Stream)作为System.Data.XmlReadMode'':类型``System.Xml.XmlDocument''的值不能转换为``System.IO.Stream''.
``公共功能ReadXml(阅读器作为System.Xml.XmlReader)作为System.Data.XmlReadMode'':不能将类型为``System.Xml.XmlDocument''的值转换为``System.Xml.XmlReader''. D:\ Seshu \ Ajaxsite \ Handler.ashx 43 9 D:\ Seshu \ Ajaxsite \

任何人都可以告诉我如何获得上述第三步.

在此先感谢
Seshu

but i am getting errors here...


Error 1 Overload resolution failed because no accessible ''ReadXml'' can be called with these arguments:
''Public Function ReadXml(fileName As String) As System.Data.XmlReadMode'': Value of type ''System.Xml.XmlDocument'' cannot be converted to ''String''.
''Public Function ReadXml(reader As System.IO.TextReader) As System.Data.XmlReadMode'': Value of type ''System.Xml.XmlDocument'' cannot be converted to ''System.IO.TextReader''.
''Public Function ReadXml(stream As System.IO.Stream) As System.Data.XmlReadMode'': Value of type ''System.Xml.XmlDocument'' cannot be converted to ''System.IO.Stream''.
''Public Function ReadXml(reader As System.Xml.XmlReader) As System.Data.XmlReadMode'': Value of type ''System.Xml.XmlDocument'' cannot be converted to ''System.Xml.XmlReader''. D:\Seshu\Ajaxsite\Handler.ashx 43 9 D:\Seshu\Ajaxsite\

anyone can tell me how to get the third step in the above.

Thanks in advance

推荐答案

您提供的参数xmldocument不是以下受支持的类型之一:

The parameter xmldocument you provide is not one of the following supported types:

fileName As String
reader As System.IO.TextReader
stream As System.IO.Stream
reader As System.Xml.XmlReader

Good luck!

这是将XML文件读入数据集的最简单方法.

That is the easiest way to read an XML file into a dataset.

dim ds as dataset
ds.readXML("c:\yourxmlfile.xml")

在此处查看可用于Dataset.ReadXML
的更多设置
MSDN:Dataset.readXML [

Have a look here for more settings that you can use with Dataset.ReadXML
