示例

本部分包含两个代码示例。This section contains two code examples. 第一个示例演示如何创建具有字段、 构造函数、 属性和方法的动态类型。The first example shows how to create a dynamic type with a field, constructor, property, and method. 第二个示例生成从用户输入动态方法。The second example builds a method dynamically from user input.

示例 1Example one

下面的代码示例演示如何定义具有一个模块的动态程序集。The following code example shows how to define a dynamic assembly with one module. 该示例程序集中模块包含一个类型, MyDynamicType,其中具有私有字段、 获取和设置私有字段的属性、 构造函数初始化的私有字段和乘以用户提供的数字的私有字段的方法值并返回结果。The module in the example assembly contains one type, MyDynamicType, which has a private field, a property that gets and sets the private field, constructors that initialize the private field, and a method that multiplies a user-supplied number by the private field value and returns the result.

AssemblyBuilderAccess.RunAndSave时创建该程序集指定字段。The AssemblyBuilderAccess.RunAndSave field is specified when the assembly is created. 立即使用的程序集代码和程序集也会保存到磁盘,以便它可以使用检查Ildasm.exe (IL 反汇编程序)或其他程序中使用。The assembly code is used immediately, and the assembly is also saved to disk so that it can be examined with Ildasm.exe (IL Disassembler) or used in another program.

注解

TypeBuilder 用于控制运行时中的动态类创建的根类。TypeBuilder is the root class used to control the creation of dynamic classes in the runtime. 它提供一的组用于定义类,添加方法和字段,并创建在模块内的类的例程。It provides a set of routines that are used to define classes, add methods and fields, and create the class inside a module. 一个新TypeBuilder可以通过调用从动态模块创建ModuleBuilder.DefineType方法,它返回TypeBuilder对象。A new TypeBuilder can be created from a dynamic module by calling the ModuleBuilder.DefineType method, which returns a TypeBuilder object.

反射发出提供了用于定义类型的以下选项:Reflection emit provides the following options for defining types:

  • 定义类或具有给定名称的接口。Define a class or interface with the given name.

  • 定义类或接口具有给定名称和属性。Define a class or interface with the given name and attributes.

  • 定义具有给定名称、 属性和基类的类。Define a class with the given name, attributes, and base class.

  • 定义具有给定名称、 属性、 基类和组的类实现的接口的类。Define a class with the given name, attributes, base class, and the set of interfaces that the class implements.

  • 定义具有给定名称、 属性、 基类和封装大小的类。Define a class with the given name, attributes, base class, and packing size.

  • 作为一个整体定义具有给定名称、 特性、 基本类和类大小的类。Define a class with the given name, attributes, base class, and the class size as a whole.

  • 作为一个整体定义具有给定名称、 属性、 基类、 封装大小和类大小的类。Define a class with the given name, attributes, base class, packing size, and the class size as a whole.

若要创建的数组类型、 指针类型或不完整类型所表示的 byref 类型TypeBuilder对象,请使用MakeArrayType方法,MakePointerType方法,或MakeByRefType方法,分别。To create an array type, pointer type, or byref type for an incomplete type that is represented by a TypeBuilder object, use the MakeArrayType method, MakePointerType method, or MakeByRefType method, respectively.

使用的类型之前,TypeBuilder.CreateType必须调用方法。Before a type is used, the TypeBuilder.CreateType method must be called. CreateType完成类型的创建过程。CreateType completes the creation of the type. 之后调用CreateType,调用方可以通过使用实例化类型Activator.CreateInstance方法,并使用调用该类型的成员Type.InvokeMember方法。Following the call to CreateType, the caller can instantiate the type by using the Activator.CreateInstance method, and invoke members of the type by using the Type.InvokeMember method. 它是错误调用更改后的类型实现的方法CreateType已调用。It is an error to invoke methods that change the implementation of a type after CreateType has been called. 例如,公共语言运行时引发异常,如果调用方尝试将新成员添加到一种类型。For example, the common language runtime throws an exception if the caller tries to add new members to a type.

通过创建一个类初始值设定项TypeBuilder.DefineTypeInitializer方法。A class initializer is created by using the TypeBuilder.DefineTypeInitializer method. DefineTypeInitializer返回ConstructorBuilder对象。DefineTypeInitializer returns a ConstructorBuilder object.

嵌套的类型定义通过调用之一TypeBuilder.DefineNestedType方法。Nested types are defined by calling one of the TypeBuilder.DefineNestedType methods.

特性Attributes

TypeBuilder类使用TypeAttributes枚举,以进一步指定要创建的类型的特征:The TypeBuilder class uses the TypeAttributes enumeration to further specify the characteristics of the type to be created:

  • 使用指定接口TypeAttributes.InterfaceTypeAttributes.Abstract属性。Interfaces are specified using the TypeAttributes.Interface and TypeAttributes.Abstract attributes.

  • 使用指定具体类 (不能扩展的类)TypeAttributes.Sealed属性。Concrete classes (classes that cannot be extended) are specified using the TypeAttributes.Sealed attribute.

  • 多个属性确定类型可见性。Several attributes determine type visibility. 请参阅的说明TypeAttributes枚举。See the description of the TypeAttributes enumeration.

  • 如果TypeAttributes.SequentialLayout类加载程序布局中,会在读取元数据中的顺序的字段的指定。If TypeAttributes.SequentialLayout is specified, the class loader lays out fields in the order they are read from metadata. 类加载程序会考虑指定的封装大小,但会忽略任何指定的字段偏移量。The class loader considers the specified packing size but ignores any specified field offsets. 元数据保留在其中发出字段定义的顺序。The metadata preserves the order in which the field definitions are emitted. 即使在合并时,元数据不重新排序的字段定义。Even across a merge, the metadata will not reorder the field definitions. 加载程序将遵循指定的字段偏移量仅当TypeAttributes.ExplicitLayout指定。The loader will honor the specified field offsets only if TypeAttributes.ExplicitLayout is specified.

已知问题Known Issues

  • 反射发出不验证实现的接口的非抽象类是否实现该接口中声明的所有方法。Reflection emit does not verify whether a non-abstract class that implements an interface has implemented all the methods declared in the interface. 但是,如果类未实现接口中声明的所有方法,在运行时不会加载类。However, if the class does not implement all the methods declared in an interface, the runtime does not load the class.

  • 尽管TypeBuilder派生自Type,在中定义的抽象方法的一些Type类中未完全实现TypeBuilder类。Although TypeBuilder is derived from Type, some of the abstract methods defined in the Type class are not fully implemented in the TypeBuilder class. 对这些调用TypeBuilder方法将引发NotSupportedException异常。Calls to these TypeBuilder methods throw a NotSupportedException exception. 可以通过检索创建的类型使用获取所需的功能Type.GetTypeAssembly.GetType和专用于反映将检索到的类型。The desired functionality can be obtained by retrieving the created type using the Type.GetType or Assembly.GetType and reflecting on the retrieved type.
