Ejemplos

En el ejemplo de código siguiente se muestra la construcción de una enumeración dentro de un ensamblado dinámico, mediante EnumBuilder. En el ejemplo se define una enumeración denominada Elevation, con un tipo subyacente de Int32y se crean dos elementos: Low, con un valor de 0 y High, con un valor de 1. Una vez creado el tipo, el ensamblado se guarda con el nombre TempAssembly.dll. Puede usar el Ildasm.exe (Desensamblador de IL) para examinar el contenido de este ensamblado.

    // and allow it to be executed and saved to disk.
    AssemblyName^ aName = gcnew AssemblyName("TempAssembly");
    AssemblyBuilder^ ab = currentDomain->DefineDynamicAssembly( 
            aName, AssemblyBuilderAccess::RunAndSave);
      
    // Define a dynamic module in "TempAssembly" assembly. For a single-
    // module assembly, the module has the same name as the assembly.
    ModuleBuilder^ mb =

    // Define a public enumeration with the name "Elevation" and an 
    // underlying type of Int32.
