// Reflection call remember that the reflected space references using system. reflection;

Assembly ASM = assembly. Load ("classlibrary2"); // reflection Space

Type type = ASM. GetType ("classlibrary2.hello"); // reflection of classes in the space

Object assclas = activator. createinstance (type); // the specified class in the specified Space Reflected by dynamic strength.

Iemploy Ie = (iemploy) assclas; // convert to interface type
