I guess you could maybe load it into a dataset, since looking at the top of the Xml file seems to have saved it from a dataset?

WriteXml - if so Here you go, here is the solution in VB.

NET but it wouldn't be that hard to translate it into C. I can reuse the extension method across projects to create an XML string from any object. I can then do whatever I please with the returned string; save it to a file, save it to a database or include it in the body of an API request. The ToXmlString method is convenient to use and provides options for overriding the default serialization behaviour see the method definition further below. The Todo class is a very simple model.

The output of the above code looks as follows. One of the slightly annoying things about the built-in serialization is that it adds superfluous XML namespaces to the output, as per the example below.

The other problem encountered when serializing is that the default character encoding of the default StringWriter class is UTF To resolve this we can sub-class the StringWriter class and pass a specific character encoding via the constructor to override the default encoding. The code to implement this is shown below. The StringWriterWithEncoding class is used in the previous code sample when creating the output stream.

The ToXmlString extension method encapsulates all of the above default behaviours nicely, without us having to remember to include the same settings and overrides in our code every time we want to serialize something.

When it comes to deserialization, we can also use an extension method, as per the sample code below. Since extension methods require an object instance to operate on, we have to new up an object before we can call the method.

Regardless, if you wanted to implement an extension method for deserialization it would look something like the code below. The problem is that the Deserialize method of the XmlSerializer included in the. NET Framework requires an object variable to assign the deserialized object to. This means that we need to new up an empty instance of the object we want to deserialize and then assign the actual deserialized object to this empty object reference to make the extension method approach work.

Due to the above problem, for deserialization, I prefer to use a static method, as per the code below. As with many things related to programming, however, it very much comes down to personal preference.
