3. here i like read the converted xmldocument using dataset
for this i tried in

VB

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\

Why you are converting from datatable to Dataset. instead you can use datatabel itself. What is the neccesity of converting Datatable to xml document and back to DataSet

From the four possible overload functions, you can see what types are acceptable as parameters to the ReadXml function. None of those match the type of the variable "xmldocument" that you are passing as parameter.

What type is the 'xmldocument' variable?
If it is an xmlDocument type then here's your problem, dataset.readXml() does not except xmlDocument as as a valid argument.

you could try passing a filename or xmlReader instead.

Solution 1

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!

Solution 2

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

VB

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

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

MSDN: Dataset.readXML[^]
