I am converting the dataset object into xml string & then passing it through socket to some client.

On the client side when the string is received & I convert the string back into dataset object & use that object as datasource for datagrid it gives me error "Root element is missing".

Code to convert datasetinto xml string:

VB

Public Shared Function ConvertObjectToByte(ByVal ds As DataSet) As String

        Dim byReturn As String = Nothing
        Dim sStream As IO.MemoryStream = Nothing

        Dim sw As New StringWriter()
        ds.WriteXml(sStream)
        byReturn = sStream.ToString()
        Return byReturn
    End Function

Code to convert string back into dataset object:

ds.ReadXml(New System.IO.StringReader(response))

Note: response is the string that I received through socket.

Any help or suggestion would definitely be appreciated.

Hi don't repost your question again and again.

Your code has many errors basically.

ds.WriteXml(sStream) won't work. WriteXml method only works with FileStreams.

byReturn = sStream.ToString() what you want to do here?

Your method says convert to byte but it returns a string. Do you understand you are confusing people here?

However if your aim is to get the xml string from data set then use the dataset's getXml() function (string resultString=ds.GetXml();). If you want to convert that string to bytes then use byte[] bytes=Encoding.Unicode.GetBytes(resultString);. If bytes back to string then string resultString1 = Encoding.Unicode.GetString(bytes);.

XML string back to Dataset

C#

TextReader reader = new StringReader(resultString1);
       DataSet ds1 = new DataSet();
       ds1.ReadXml(reader);

It is unclear how you transfer your byte or string to another client. So that is your headache. if you transfer the right data and get right data it will work fine.

Good luck.
