개요

<environmentVariables> 요소의 <applicationPools>/<add> 요소는 애플리케이션이 시작될 때 IIS(인터넷 정보 서비스) 10이 작업자 프로세스에 전달할 환경 변수 목록을 지정합니다. <environmentVariables> 요소는 각 환경 변수에 대한 개별 이름/값 쌍을 정의하는 요소의 <add> 컬렉션을 포함합니다.

호환성

버전	참고
IIS 10.0	요소는 `<environmentVariables>` IIS 10에서 도입되었습니다.
IIS 8.0	해당 없음
IIS 7.5	해당 없음
IIS 7.0	해당 없음
IIS 6.0	해당 없음

설치 프로그램

요소는 <environmentVariables> IIS 10의 기본 설치에 포함됩니다.

방법

IIS 10에 대한 환경 변수를 설정하기 위한 사용자 인터페이스가 없습니다. 환경 변수를 프로그래밍 방식으로 설정하는 방법에 대한 예제는 이 문서의 코드 샘플 섹션을 참조하세요.

구성

특성

없음

자식 요소

요소	Description
`add`	선택적 요소입니다. 환경 변수의 컬렉션에 환경 변수를 추가합니다.
`remove`	선택적 요소입니다. 환경 변수 컬렉션에서 환경 변수를 제거합니다.

구성 샘플

다음 예제에서는 애플리케이션 풀에 환경 변수를 추가합니다.

<applicationPools>
   <add name="Contoso" managedRuntimeVersion="v4.0" managedPipelineMode="Classic">
      <environmentVariables>
         <add name="foo" value="bar" />
      </environmentVariables>
   </add>
</applicationPools>

샘플 코드

다음 예제에서는 환경 변수 컬렉션에 이름/값 쌍을 추가하는 방법을 보여 줍니다.
