Примеры

В следующем примере кода определяется универсальный метод с именем, DemoMethod тип и тип возвращаемого значения которого указываются с помощью параметров универсального типа.The following code example defines a generic method named DemoMethod whose parameter type and return type are specified by its generic type parameters. Метод определяется без сигнатуры с использованием стандартного соглашения о вызовах.The method is defined without a signature, using the standard calling convention. MethodBuilder.DefineGenericParametersМетод используется для создания DemoMethod универсального метода, а вновь определенные параметры типа используются для сигнатуры и типа возвращаемого значения.The MethodBuilder.DefineGenericParameters method is used to make DemoMethod a generic method, and the newly defined type parameters are then used for the signature and return type.

Этот пример кода является частью большого примера, приведенного для DefineGenericParameters метода.This code example is part of a larger example provided for the DefineGenericParameters method.

// Define a Shared, Public method with standard calling

Используйте эту перегрузку метода, если подпись метода не известна во время определения метода.Use this method overload when you do not know the method signature at the time you define the method. Например, типы параметров и возвращаемый тип универсального метода могут быть заданы параметрами универсального типа метода, которые должны быть определены после добавления метода к типу.For example, the parameter types and return type of a generic method might be specified by the method's generic type parameters, which must be defined after the method has been added to the type. Параметры и возвращаемый тип метода можно задать позже с помощью MethodBuilder.SetSignature метода.The parameters and return type of the method can be set later using the MethodBuilder.SetSignature method.

Этот перегруженный метод определяет метод с CallingConventions.Standard .This method overload defines a method with CallingConventions.Standard. Если необходимо определить метод без сигнатуры с другим соглашением о вызовах, используйте DefineMethod(String, MethodAttributes, CallingConventions) перегрузку метода.If you need to define a method without a signature, with a different calling convention, use the DefineMethod(String, MethodAttributes, CallingConventions) method overload.

Используйте эту перегрузку, если необходимо указать настраиваемые модификаторы.Use this overload if you need to specify custom modifiers. Если после создания метода необходимо указать пользовательские модификаторы, то, например, с универсальным методом, типы параметров которого указываются с помощью параметров универсального типа, можно использовать DefineMethod(String, MethodAttributes) DefineMethod(String, MethodAttributes, CallingConventions) перегрузки метода или, чтобы определить метод, а затем использовать MethodBuilder.SetSignature метод для определения параметров и возвращаемых типов с пользовательскими модификаторами.If you need to specify custom modifiers after the method has been created, as you would, for example, with a generic method whose parameter types are specified by its generic type parameters, you can use the DefineMethod(String, MethodAttributes) or DefineMethod(String, MethodAttributes, CallingConventions) method overloads to define the method and then use the MethodBuilder.SetSignature method to define the parameter and return types with custom modifiers.
