How to Update the XML file

[cathy25]

Hi,

I am trying to get data from a xml file, and I am trying to update the xml file depending on some condition.
I wrote the following code.

MemoryStream inStream = new MemoryStream(MYFile.OpenBinary());
            XmlTextReader reader = new XmlTextReader(inStream);
            XmlDocument xd = new XmlDocument();
            xd.Load(reader);
            reader.Close();
            inStream.Close();
After reading the file, I am trying to update the file using the following code.
 
if(Condition) //my codition
{
Node1.InnerText="MYCOMPUTER"  // before node1 contains "system"
MemoryStream outStream = new MemoryStream(MYFile.OpenBinary ()); 
                            XmlTextWriter writer = new XmlTextWriter(outStream , Encoding.ASCII);
                        xd.Save(writer);
                        writer.Close();
                        outStream.Close();
}
 

It is not giving me any error, but it is not updating the xml file.
Am I missing any thing?

Help in this regard is greately appreciated.

Thanks

I have also tried by changing the out stream as

MemoryStream outStream = new MemoryStream(APQPFile.GetHashCode ());

still it is not updating the xml file.

Please any body give me reply.
