Question

I have an XML document that contains the following structure:

Its more or less a collection of Events:

<Events>
  <Event>
    <DateTime></DateTime>
    <EventType></EventType>
    <Result></Result>
    <Provider></Provider>
    <ErrorMessage></ErrorMessage>
    <InnerException></InnerException>
  </Event>
</Events>

In C# I have a persistent object called Event:

Now given that the document already exists, and saved to file… I call :

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(dataPath);

Now how can I add a new Event item to events?

I’ve got a strongly typed Event item in my C# code, and want it inserted into the Events collection in the XML object as last child.

I guess this is what I am really asking : https://stackoverflow.com/questions/1457033/c-insert-a-strongly-typed-object-as-node-in-existing-xml-document

Just hand code it using the XmlDocument. You can add a class that does the conversion or insertion into the document you are going to save.

This is based on the restriction of .net 2.0 and what you said in these comments:

• @Fred, I want to try minimize the write time, hence the reason for not writing all at once, the less write time in this app, the less chance of file corruption. – JL 16 mins ago
