ModuleBuilder 类
定义并表示模块。通过调用 DefineDynamicModule 获取 ModuleBuilder 的实例。
**命名空间:**System.Reflection.Emit
**程序集:**mscorlib（在 mscorlib.dll 中）

备注
提示
应用于此类的 HostProtectionAttribute 属性 (Attribute) 具有以下 Resources 属性 (Property) 值：MayLeakOnAbort。HostProtectionAttribute 不影响桌面应用程序（桌面应用程序一般通过双击图标，键入命令或在浏览器中输入 URL 启动）。有关更多信息，请参见 HostProtectionAttribute 类或 SQL Server 编程和宿主保护属性。
示例
下面的代码示例演示了如何使用 ModuleBuilder 创建动态模块。请注意 ModuleBuilder 是通过调用 AssemblyBuilder 中的 DefineDynamicModule 创建的，而不是通过构造函数创建的。
