AssemblyName Constructor

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Initializes a new instance of the AssemblyName class.

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

Syntax

'Declaration
Public Sub New

public AssemblyName()

Examples

The following example creates an AssemblyName and then uses it to create a dynamic assembly.

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

Imports System.Reflection
Imports System.Threading
Imports System.Reflection.Emit

Public Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      ' Create a dynamic assembly with name 'MyAssembly' and build version '1.0.0.2001'.
      Dim myAssemblyName As New AssemblyName()
      myAssemblyName.Name = "MyAssembly"
      myAssemblyName.Version = New Version("1.0.0.2001")

      ' Get the assembly builder from the application domain associated with 
      ' the current thread.
      Dim myAssemblyBuilder As AssemblyBuilder = _
         AppDomain.CurrentDomain.DefineDynamicAssembly(myAssemblyName, _
            AssemblyBuilderAccess.Run)

      ' Create a dynamic module in the assembly.
      Dim myModuleBuilder As ModuleBuilder = myAssemblyBuilder.DefineDynamicModule("MyModule")
      ' Create a type in the module.
      Dim myTypeBuilder As TypeBuilder = myModuleBuilder.DefineType("MyType", _
