The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Occurs when an assembly is loaded.

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

Public Event AssemblyLoad As AssemblyLoadEventHandler

The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

For more information about handling events, see Handling and Raising Events.

The following sample demonstrates the AssemblyLoad event.

For this code example to run, you must provide the fully qualified assembly name. For information about how to obtain the fully qualified assembly name, see Assembly Names.

Imports System.Reflection

Module Test

   Sub Main()
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain
      AddHandler currentDomain.AssemblyLoad, AddressOf MyAssemblyLoadEventHandler

      ' Lists mscorlib and this assembly

      ' You must supply a valid fully qualified assembly name here.      
      currentDomain.CreateInstance("System.Windows.Forms,Version,Culture,PublicKeyToken", "System.Windows.Forms.TextBox")
      ' Loads System, System.Drawing, System.Windows.Forms

      ' Lists all five assemblies
   End Sub 'Main

   Sub PrintLoadedAssemblies(domain As AppDomain)
      Console.WriteLine("LOADED ASSEMBLIES:")
      Dim a As System.Reflection.Assembly
      For Each a In domain.GetAssemblies()
      Next a
   End Sub 'PrintLoadedAssemblies

   Sub MyAssemblyLoadEventHandler(sender As Object, args As AssemblyLoadEventArgs)
