Type.GetMembers Method

Returns all the public members of the current Type.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public Function GetMembers As MemberInfo()

Return Value

Type: System.Reflection.MemberInfo()
An array of MemberInfo objects representing all the public members of the current Type.
An empty array of type MemberInfo, if the current Type does not have public members.



Members include properties, methods, fields, events, and so on.

The GetMembers method does not return members in a particular order, such as alphabetical or declaration order. Your code must not depend on the order in which members are returned, because that order varies.

This method overload calls the GetMembers(BindingFlags) method overload, with BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static (BindingFlags.Public Or BindingFlags.Instance Or BindingFlags.Static in Visual Basic). It will not find class initializers (.cctor). To find class initializers, use an overload that takes BindingFlags, and specify BindingFlags.Static | BindingFlags.NonPublic (BindingFlags.Static Or BindingFlags.NonPublic in Visual Basic). You can also get the class initializer using the TypeInitializer property.

The following table shows what members of a base class are returned by the Get methods when reflecting on a type.

Member Type








Yes. A field is always hide-by-name-and-signature.


Not applicable

The common type system rule is that the inheritance is the same as that of the methods that implement the property. Reflection treats properties as hide-by-name-and-signature. See note 2 below.



Yes. A method (both virtual and non-virtual) can be hide-by-name or hide-by-name-and-signature.

Nested Type




Not applicable

The common type system rule is that the inheritance is the same as that of the methods that implement the property. Reflection treats properties as hide-by-name-and-signature. See note 2 below.

  1. Hide-by-name-and-signature considers all of the parts of the signature, including custom modifiers, return types, parameter types, sentinels, and unmanaged calling conventions. This is a binary comparison.

  2. For reflection, properties and events are hide-by-name-and-signature. If you have a property with both a get and a set accessor in the base class, but the derived class has only a get accessor, the derived class property hides the base class property, and you will not be able to access the setter on the base class.

  3. Custom attributes are not part of the common type system.

If the current Type represents a constructed generic type, this method returns the MemberInfo objects with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the members of the class constraint, or the members of Object if there is no class constraint.

The following code example demonstrates how to use the GetMembers method overload to collect information about all public members of a specified class.

Class [MyClass]
   Public myInt As Integer = 0
   Public myString As String = Nothing

   Public Sub New()
   End Sub 'New

   Public Sub Myfunction()
   End Sub 'Myfunction
End Class '[MyClass]

Class Type_GetMembers

   Public Shared Sub Main()
         Dim myObject As New [MyClass]()
         Dim myMemberInfo() As MemberInfo

         ' Get the type of 'MyClass'.
         Dim myType As Type = myObject.GetType()

         ' Get the information related to all public member's of 'MyClass'. 
         myMemberInfo = myType.GetMembers()

         Console.WriteLine(ControlChars.Cr + "The members of class '{0}' are :" + ControlChars.Cr, myType)
         Dim i As Integer
         For i = 0 To myMemberInfo.Length - 1
            ' Display name and type of the concerned member.
            Console.WriteLine("'{0}' is a {1}", myMemberInfo(i).Name, myMemberInfo(i).MemberType)
         Next i

      Catch e As SecurityException
         Console.WriteLine(("Exception : " + e.Message.ToString()))
      End Try
   End Sub 'Main
End Class 'Type_GetMembers
