방법: Windows Forms BindingSource를 사용하여 웹 서비스에 바인딩

아티클

업데이트: 2007년 11월

XML Web services를 호출하여 얻은 결과에 Windows Form 컨트롤을 바인딩하려는 경우 BindingSource 구성 요소를 사용하면 됩니다. 이 절차는 형식에 BindingSource 구성 요소를 바인딩하는 절차와 비슷합니다. Web services에서 노출되는 형식과 메서드를 포함하는 클라이언트측 프록시를 만들어야 합니다. 클라이언트측 프록시는 Web services(.asmx) 자체나 해당 WSDL(웹 서비스 설명 언어) 파일을 통해 생성합니다. 또한 클라이언트측 프록시에서는 Web services에서 사용되는 복잡한 형식의 필드를 공용 속성으로 노출해야 합니다. 그런 다음 Web services 프록시에서 노출되는 형식 중 하나로 BindingSource를 바인딩합니다.

Windows Form 컨트롤을 만들어 클라이언트측 프록시에 바인딩하려면

선택한 디렉터리에 적절한 네임스페이스를 사용하여 Windows Form을 만듭니다.
BindingSource 구성 요소를 폼에 추가합니다.
Windows SDK(소프트웨어 개발 키트) 명령 프롬프트를 열고 폼이 있는 디렉터리로 이동합니다.
wsdl을 입력한 다음 Web services에 대한 WSDL 파일 또는 .asmx의 URL과 응용 프로그램의 네임스페이스 및 사용 중인 언어(옵션)를 입력합니다.

다음 코드 예제에서는 http://webservices.eraserver.net/zipcoderesolver/zipcoderesolver.asmx에 있는 Web services를 사용합니다. 예를 들어, C#의 경우 wsdl http://webservices.eraserver.net.zipcoderesolver/zipcoderesolver.asmx /n:BindToWebService를 입력하고 Visual Basic의 경우 wsdl http://webservices.eraserver.net.zipcoderesolver/zipcoderesolver.asmx /n:BindToWebService /language:VB를 입력합니다. 경로를 WSDL 도구에 인수로 전달하면 사용 중인 응용 프로그램과 동일한 디렉터리 및 네임스페이스에 지정된 언어로 클라이언트측 프록시가 생성됩니다. 현재 Visual Studio를 사용 중이면 파일을 프로젝트에 추가합니다.

바인딩할 클라이언트측 프록시에서 형식을 선택합니다.

일반적으로 이 형식은 Web services가 제공하는 메서드에서 반환되는 형식입니다. 선택한 형식의 필드는 바인딩을 위해 공용 속성으로 노출되어야 합니다.

BindingSource의 DataSource 속성을 Web services 클라이언트측 프록시에 포함된 형식 중 원하는 형식으로 설정합니다.

BindingSource1.DataSource = GetType(USPSAddress)

         BindingSource1.DataSource = typeof(USPSAddress);

            BindingSource1->DataSource = USPSAddress::typeid;

Web services에 바인딩된 BindingSource에 컨트롤을 바인딩하려면

Web services 형식의 원하는 공용 속성을 매개 변수로 전달하여 BindingSource에 컨트롤을 바인딩합니다.

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

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

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