My understanding is, "is" actually stands for "is an instance of type..".
i.e. it basically compares the "type" of the object on the LHS with the
actual type on the RHS. Going by that definition, you are actually
comparing the type of your instance to the type XmlNode, rather than
comparing the actual instance of XmlNode. You should instead try:
if (parameters[0] is System.Xml.XmlNode)
{
...
}
