TypeInfo

Class (inherits from MemberInfo)

Gets information about a program’s structure. It is an abstract class whose properties and functions describe all the attributes or members a datatype might have.

Properties

BaseType IsEnum IsProtected FullName IsInterface IsPublic HasElementType IsPointer IsValueType IsArray IsPrimitive Name IsClass IsPrivate

Methods

GetArrayRank GetElementType IsSubclassOf GetAttributes GetMethods GetConstructors GetProperties

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 DateTime = DateTime.Now
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
