방법: 코드에서 클라이언트 바인딩 지정

2025-04-09

이 예제에서는 계산기 서비스를 사용하기 위해 클라이언트가 만들어지고 해당 클라이언트에 대한 바인딩이 코드에서 명령적으로 지정됩니다. 클라이언트는 인터페이스를 CalculatorService구현하는 ICalculator 에 액세스하고 서비스와 클라이언트 모두 클래스를 BasicHttpBinding 사용합니다.

이 절차에서는 계산기 서비스가 실행 중이라고 가정합니다. 서비스 빌드에 대한 자세한 내용은 방법: 구성에서 서비스 바인딩 지정을 참조하세요. 또한 ServiceModel 메타데이터 유틸리티 도구(Svcutil.exe)WCF(Windows Communication Foundation)를 사용하여 클라이언트 구성 요소를 자동으로 생성합니다. 이 도구는 서비스에 액세스하기 위한 클라이언트 코드를 생성합니다.

클라이언트는 두 부분으로 빌드됩니다. Svcutil.exe은 ICalculator 인터페이스를 구현하는 ClientCalculator을 생성합니다. 그런 다음, 이 클라이언트 애플리케이션은 인스턴스 ClientCalculator 를 생성한 다음 코드에서 서비스의 바인딩 및 주소를 지정하여 생성됩니다.

이 예제의 원본 복사본은 BasicBinding 샘플을 참조하세요.

코드에서 사용자 지정 바인딩을 지정하려면

명령줄의 Svcutil.exe 사용하여 서비스 메타데이터에서 코드를 생성합니다.
```
Svcutil.exe <service's Metadata Exchange (MEX) address or HTTP GET address>
```

생성된 클라이언트에는 클라이언트 구현이 충족해야 하는 서비스 계약을 정의하는 #D0 인터페이스가 포함되어 있습니다.
