방법: Windows Forms BindingSource를 사용하여 웹 서비스에 바인딩

아티클

XML Web services 호출에서 얻은 결과에 Windows Form 컨트롤을 바인딩하려면 BindingSource 구성 요소를 사용하면 됩니다. 이 절차는 BindingSource 구성 요소를 형식에 바인딩하는 것과 비슷합니다. 웹 서비스에 의해 노출되는 메서드와 형식이 포함된 클라이언트 측 프록시를 만들어야 합니다. 웹 서비스(.asmx) 자체 또는 WSDL(Web Services Description Language) 파일에서 클라이언트 측 프록시를 생성합니다. 또한 클라이언트 측 프록시는 웹 서비스에서 공용 속성으로 사용되는 복합 형식의 필드를 노출해야 합니다. 그리고 나서 BindingSource를 웹 서비스 프록시에 노출된 형식의 하나에 바인딩합니다.

클라이언트 측 프록시를 만들고 바인딩하려면 다음을 수행합니다.

적절한 네임스페이스를 사용하여 선택한 디렉터리에서 Windows Form을 만듭니다.
폼에 BindingSource 구성 요소를 추가합니다.
Windows SDK(소프트웨어 개발 키트) 명령 프롬프트를 열고 양식이 있는 같은 디렉터리로 이동합니다.
WSDL 도구를 사용하여 wsdl, 웹 서비스에 대한 .asmx 또는 WSDL 파일의 URL, 애플리케이션의 네임스페이스를 차례로 입력하고 선택적으로 사용 중인 언어를 입력합니다.

다음 코드 예제에서는 http://webservices.eraserver.net/zipcoderesolver/zipcoderesolver.asmx에 있는 웹 서비스를 사용합니다. 예를 들어 C# 유형 wsdl http://webservices.eraserver.net.zipcoderesolver/zipcoderesolver.asmx /n:BindToWebService 또는 Visual Basic 유형 wsdl http://webservices.eraserver.net.zipcoderesolver/zipcoderesolver.asmx /n:BindToWebService /language:VB의 경우입니다. WSDL 도구에 경로를 인수로 전달하면 지정된 언어로 애플리케이션과 같은 디렉터리 및 네임스페이스에 클라이언트 측 프록시가 생성됩니다. Visual Studio를 사용하는 경우 프로젝트에 파일을 추가합니다.

바인딩할 클라이언트 측 프록시의 형식을 선택합니다.

이는 일반적으로 웹 서비스에서 제공된 메서드가 반환한 형식입니다. 선택된 형식의 필드는 바인딩용 공용 속성으로 노출되어야 합니다.

BindingSource의 DataSource 속성을 웹 서비스 클라이언트 측 프록시에 포함된 원하는 형식으로 설정합니다.

BindingSource1->DataSource = USPSAddress::typeid;

BindingSource1.DataSource = typeof(USPSAddress);

BindingSource1.DataSource = GetType(USPSAddress)

웹 서비스에 바인딩된 BindingSource에 컨트롤을 바인딩하려면 다음을 수행합니다.

컨트롤을 BindingSource에 바인딩하여 원하는 웹 서비스 형식의 공용 속성을 매개 변수로 전달합니다.

textBox1->DataBindings->Add("Text", this->BindingSource1, "FullZIP", true);

textBox1.DataBindings.Add("Text", this.BindingSource1, "FullZIP", true);

textBox1.DataBindings.Add("Text", Me.BindingSource1, "FullZIP", True)
