I am having a problem using XML Serialization.

I have a class that serializes an object and saves it to disk, (sort of a
page file system for a web app).

You pass in the object, and the serialization method to use and it will
serialize it to disk for later retrievel.

The following scenarios work great:

1. Serializing anything with Binary Serialization
2. Serializing any type in the System namespace with XML Serialization

The following scenario is where I am having difficulty:

3. Serializing any type not in the System namespace (ie System.Data.Dataset)

The problem actually occurs in the deserialization when I am trying to
retrieve the type of the object to pass it to the constructor of the
XmlSerializer object.

Here is the code that is giving me trouble:

   Type oType = Type.GetType(oNode.Attributes["type"].InnerText,true, true);

For example, when I am trying to deserialize a Dataset object, the InnerText
property of this node is set to "System.Data.Dataset", and I receive the
following exception at that line of code:

System.TypeLoadException : Could not load type System.Data.DataSet from
assembly PageFileManager

(PageFileManager is the calling class)

So my two questions are:

1. Am I missing a step here where I need to use reflection to load some
assembly.

or

2. Is there a way  to deserialize XML without specifying the type in the
constructor of the XmlSerializer object?

Thanks in advance,
