You can apply this attribute to methods, fields, or properties.
This attribute contains the DISPID for the method, field, or property it describes. Unique DISPIDs are typically assigned by the common language runtime, but you can use this attribute to assign a specific DISPID to a method. When importing a type library, this attribute is applied to all methods with assigned DISPIDs. This ensures that any managed implementation of the same method retains the same DISPID if exposed to COM.
The following example demonstrates how explicit DISPIDs can be assigned to members of a class.
Imports System.Runtime.InteropServices Class SampleClass Public Sub New() 'Insert code here. End Sub <DispIdAttribute(8)> _ Public Sub MyMethod() 'Insert code here. End Sub Public Function MyOtherMethod() As Integer 'Insert code here. Return 0 End Function <DispId(9)> _ Public MyField As Boolean End Class
