Notes

TypeInfo is part of the Introspection namespace (module) so you'll have to prefix it and refer to it as "Introspection.TypeInfo".

Sample Code

The following returns PropertyInfo and MethodInfo arrays containing the properties and methods of the passed class instance.

Var d As New Date
Var myProperties() As Introspection.PropertyInfo = _
Introspection.GetType(d).GetProperties
Var myMethods() As Introspection.MethodInfo = _
Introspection.GetType(d).GetMethods
// display the properties...
For Each prop As Introspection.PropertyInfo In myProperties
ListBox1.AddRow(prop.Name)
Next

This example gets the ConstructorInfo for the FolderItem class and creates a new instance of a FolderItem.

Var ti As Introspection.Typeinfo = GetTypeInfo(FolderItem)
Var ci() As Introspection.ConstructorInfo = ti.GetConstructors
Var f As FolderItem
f = ci(0).invoke
