Assembly

 object. The 

Assembly

 class does not define a public constructor. Instead, an 

Assembly

 object is obtained 

by calling one of its methods. The one we will use is 

LoadFrom( )

, which loads an assembly 

given its filename. The form we will use is shown here:

static Assembly LoadFrom(string 

fi lename

)

Here, 

filename

 specifies the filename of the assembly.

Once you have obtained an 

Assembly

 object, you can discover the types that it defines 

by calling 

GetTypes( )

 on it. Here is its general form:

Type[ ] GetTypes( )

It returns an array of the types contained in the assembly.

To demonstrate the discovery of types in an assembly, you will need two files. The first 

will contain a set of classes that will be discovered by the second. To begin, create a file 

called

MyClasses.cs

 that contains the following:

// A file that contains three classes. Call this file MyClasses.cs.

using System;

class MyClass {

  int x;

  int y;

  public MyClass(int i) {

    Console.WriteLine("Constructing MyClass(int). ");

    x = y = i;

    Show();

  }

  public MyClass(int i, int j) {

    Console.WriteLine("Constructing MyClass(int, int). ");

    x = i;

    y = j;
