本文通过MSDN上的示例介绍了如何使用C#在运行时动态创建枚举类型，并将其保存到磁盘的过程。该过程涉及获取当前应用程序域、定义动态程序集、模块及枚举等步骤。

MSDN上的列子，注意动态创建的顺序，Domain->assembley->module->enum 这个过程，如果我要动态建class是不是也是这个步骤？

// Get the current application domain for the current thread. AppDomain currentDomain = AppDomain.CurrentDomain; // Create a dynamic assembly in the current application domain, // and allow it to be executed and saved to disk. AssemblyName aName = new 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 = ab.DefineDynamicModule(aName.Name, aName.Name + ".dll"); // Define a public enumeration with the name "Elevation" and an // underlying type of Integer. EnumBuilder eb = mb.DefineEnum("Elevation", TypeAttributes.Public, typeof(int)); // Define two members, "High" and "Low". eb.DefineLiteral("Low", 0); eb.DefineLiteral("High", 1); // Create the type and save the assembly. Type finished = eb.CreateType(); ab.Save(aName.Name + ".dll"); foreach (object o in Enum.GetValues(finished)) { Console.WriteLine("{0}.{1} = {2}", finished, o, ((int)o)); } Console.ReadKey();
