Public Class Example
    Public Shared Sub Main()
        ' Define a dynamic assembly to contain the sample type. The
        ' assembly will not be run, but only saved to disk, so
        ' AssemblyBuilderAccess.Save is specified.

        ' An assembly is made up of executable modules. For a single-
        ' module assembly, the module name and file name are the same 
        ' as the assembly name. 
        '

            myAsmName.Name, _

        ' Define a method that takes a ByRef argument of type Sample,
        ' a pointer to type Sample, and an array of Sample objects. The
        ' method returns a two-dimensional array of Sample objects.
        '
        ' To create this method, you need Type objects that represent the
        ' parameter types and the return type. Use the MakeByRefType, 
        ' MakePointerType, and MakeArrayType methods to create the Type
        ' objects.

        ' Define the abstract Test method. After you have compiled
        ' and run this code example code, you can use ildasm.exe 
        ' to open MakeXxxTypeExample.dll, examine the Sample type,
        ' and verify the parameter types and return type of the
        ' TestMethod method.

            parameterTypes)

        ' Create the type and save the assembly. For a single-file 
        ' assembly, there is only one module to store the manifest 
        ' information in.
        '
