Well, it does not seem to be so simple? The following snippet:
Type attrType = typeof(System.Xml.XmlAttribute);
Type nodeType = typeof(System.Xml.XmlNode);
if (attrType == nodeType)
Console.WriteLine("is an instance of XmlNode");
else
if (nodeType.IsAssignableFrom(attrType))
Console.WriteLine("XmlNode is assignable from this type");
produces "XmlNode is assignable from this type". XmlNode is an abstract
class, so type equality cannot be true. Instead, IsAssignableFrom() should
be used. From the docs:
Type.IsAssignableFrom
Return Value
true if the c parameter and the current Type represent the same type, or if
the current Type is in the inheritance hierarchy of c, or if the current
Type is an interface that c supports. false if none of these conditions are
the case, or if c is a null reference (Nothing in Visual Basic).
So, use
typeof(System.Xml.XmlNode).IsAssignableFrom(parameters[0].ParameterType)
