示例

下面的代码示例使用两个类型参数,创建一个泛型类型,并将它们保存在程序集 GenericEmitExample1.dll。The following code example creates a generic type with two type parameters, and saves them in the assembly GenericEmitExample1.dll. 可以使用Ildasm.exe (IL 反汇编程序)若要查看生成的类型。You can use the Ildasm.exe (IL Disassembler) to view the generated types. 定义动态的泛型类型中涉及的步骤的更多详细说明,请参阅如何:使用反射发出定义泛型类型For a more detailed explanation of the steps involved in defining a dynamic generic type, see How to: Define a Generic Type with Reflection Emit.

        ' Now it is possible to get the constructor of List(Of T),

注解

可以获取的数组GenericTypeParameterBuilder通过使用对象TypeBuilder.DefineGenericParameters方法将类型参数添加到动态类型,从而使其泛型类型,或使用MethodBuilder.DefineGenericParameters方法将类型参数添加到动态方法。You can get an array of GenericTypeParameterBuilder objects by using the TypeBuilder.DefineGenericParameters method to add type parameters to a dynamic type, thus making it a generic type, or by using the MethodBuilder.DefineGenericParameters method to add type parameters to a dynamic method. 使用GenericTypeParameterBuilder要将约束添加到类型参数的对象。Use the GenericTypeParameterBuilder objects to add constraints to the type parameters. 约束有三种:Constraints are of three kinds:

  • 基类型约束指定泛型类型参数分配任何类型必须从特定的基类型派生。The base type constraint specifies that any type assigned to the generic type parameter must derive from a particular base type. 通过设置此约束SetBaseTypeConstraint方法。Set this constraint by using the SetBaseTypeConstraint method.

  • 接口约束指定泛型类型参数分配任何类型必须实现特定接口。An interface constraint specifies that any type assigned to the generic type parameter must implement a particular interface. 通过设置接口约束SetInterfaceConstraints方法。Set the interface constraints by using the SetInterfaceConstraints method.

  • 特殊约束指定任何类型分配给泛型类型参数必须具有默认构造函数,必须是引用类型,或者必须是值类型。Special constraints specify that any type assigned to the generic type parameter must have a default constructor, must be a reference type, or must be a value type. 使用设置为类型参数的特殊约束SetGenericParameterAttributes方法。Set the special constraints for a type parameter by using the SetGenericParameterAttributes method.

不能使用的方法检索到接口约束和特殊约束GenericTypeParameterBuilder类。Interface constraints and special constraints cannot be retrieved using methods of the GenericTypeParameterBuilder class. 创建包含的类型参数的泛型类型后,可以使用其Type对象以反映约束。Once you have created the generic type that contains the type parameters, you can use its Type object to reflect the constraints. 使用Type.GetGenericArguments方法以获取类型参数,并为每个类型参数使用Type.GetGenericParameterConstraints方法以获取该基类型约束和接口约束和Type.GenericParameterAttributes要获取的特殊约束属性。Use the Type.GetGenericArguments method to get the type parameters, and for each type parameter use the Type.GetGenericParameterConstraints method to get the base type constraint and interface constraints, and the Type.GenericParameterAttributes property to get the special constraints.
