Examples

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使用字段、构造函数、属性和方法创建动态类型。The first example shows how to create a dynamic type with a field, constructor, property, and method. 第二个示例从用户输入动态生成方法。The second example builds a method dynamically from user input.

示例一Example one

下面的代码示例演示如何使用一个模块定义动态程序集。The following code example shows how to define a dynamic assembly with one module. 示例程序集中的模块包含一种类型,MyDynamicType,其中包含一个私有字段、一个用于获取和设置私有字段的属性、用于初始化私有字段的构造函数,以及一个方法,该方法将用户提供的数字与私有字段值相乘并返回结果。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 字段是在创建程序集时指定的。The AssemblyBuilderAccess.RunAndSave field is specified when the assembly is created. 系统将立即使用程序集代码,并将程序集保存到磁盘,以便可以使用Ildasm (IL 拆装器)或在其他程序中使用它来检查程序集代码。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.

Remarks

TypeBuilder 是用于控制在运行时中创建动态类的根类。TypeBuilder is the root class used to control the creation of dynamic classes in the runtime. 它提供一组例程,用于定义类、添加方法和字段,以及在模块中创建类。It provides a set of routines that are used to define classes, add methods and fields, and create the class inside a module. 可以通过调用返回 TypeBuilder 对象的 ModuleBuilder.DefineType 方法,从动态模块创建新 TypeBuilderA new TypeBuilder can be created from a dynamic module by calling the ModuleBuilder.DefineType method, which returns a TypeBuilder object.

反射发出提供以下用于定义类型的选项:Reflection emit provides the following options for defining types:

  • 定义具有给定名称的类或接口。Define a class or interface with the given name.

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

  • 使用给定的名称、属性和基类定义类。Define a class with the given name, attributes, and base class.

  • 使用给定的名称、属性、基类和类实现的接口集定义类。Define a class with the given name, attributes, base class, and the set of interfaces that the class implements.

  • 使用给定的名称、属性、基类和封装大小定义类。Define a class with the given name, attributes, base class, and packing size.

  • 使用给定的名称、属性、基类和类大小作为一个整体来定义类。Define a class with the given name, attributes, base class, and the class size as a whole.

  • 使用给定的名称、属性、基类、包装大小和类大小作为一个整体来定义类。Define a class with the given name, attributes, base class, packing size, and the class size as a whole.

若要为 TypeBuilder 对象表示的不完整类型创建数组类型、指针类型或 byref 类型,请分别使用 MakeArrayType 方法、MakePointerType 方法或 MakeByRefType 方法。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.

使用类型之前,必须先调用 TypeBuilder.CreateType 方法。Before a type is used, the TypeBuilder.CreateType method must be called. CreateType完成类型的创建。CreateType completes the creation of the type. 调用CreateType后,调用方可以使用 Activator.CreateInstance 方法来实例化该类型,并通过使用 Type.InvokeMember 方法调用该类型的成员。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. 调用CreateType后,调用更改类型实现的方法是错误的。It is an error to invoke methods that change the implementation of a type after CreateType has been called. 例如,如果调用方尝试向类型中添加新成员,则公共语言运行时将引发异常。For example, the common language runtime throws an exception if the caller tries to add new members to a type.

类初始值设定项是使用 TypeBuilder.DefineTypeInitializer 方法创建的。A class initializer is created by using the TypeBuilder.DefineTypeInitializer method. DefineTypeInitializer返回 ConstructorBuilder 的对象。DefineTypeInitializer returns a ConstructorBuilder object.

嵌套类型是通过调用 TypeBuilder.DefineNestedType 方法之一来定义的。Nested types are defined by calling one of the TypeBuilder.DefineNestedType methods.

特性Attributes

TypeBuilder 类使用 TypeAttributes 枚举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:

  • 接口是使用 TypeAttributes.InterfaceTypeAttributes.Abstract 属性指定的。Interfaces are specified using the TypeAttributes.Interface and TypeAttributes.Abstract attributes.

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

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

  • 如果指定了 TypeAttributes.SequentialLayout,类加载程序将按从元数据中读取字段的顺序对它们进行布局。If TypeAttributes.SequentialLayout is specified, the class loader lays out fields in the order they are read from metadata. 类加载器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. 元数据保留发出字段定义的顺序。The metadata preserves the order in which the field definitions are emitted. 甚至跨合并,元数据也不会对字段定义重新排序。Even across a merge, the metadata will not reorder the field definitions. 仅当指定 TypeAttributes.ExplicitLayout 时,加载程序才服从指定的字段偏移量。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接口的非抽象类是否实现了在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,如果类未实现在接口中声明的所有方法,则运行时不会加载类。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,但 Type 类中定义的某些抽象方法未在 TypeBuilder 类中完全实现。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 TypeBuilder 方法的调用将引发 NotSupportedException 异常。Calls to these TypeBuilder methods throw a NotSupportedException exception. 可以通过使用 Type.GetTypeAssembly.GetType 检索创建的类型并在检索的类型上进行反射来获取所需的功能。The desired functionality can be obtained by retrieving the created type using the Type.GetType or Assembly.GetType and reflecting on the retrieved type.
