CallContext.SetData(String, Object) 메서드

정의

네임스페이스:

System.Runtime.Remoting.Messaging

어셈블리:

mscorlib.dll

지정된 개체를 저장하고 이를 지정한 이름에 연결합니다.

public:
 static void SetData(System::String ^ name, System::Object ^ data);

[System.Security.SecurityCritical]
public static void SetData (string name, object data);

[<System.Security.SecurityCritical>]
static member SetData : string * obj -> unit

Public Shared Sub SetData (name As String, data As Object)

매개 변수

name

String

호출 컨텍스트의 새 항목과 연결할 이름입니다.

data

Object

호출 컨텍스트에 저장할 개체입니다.

특성

SecurityCriticalAttribute

예외

SecurityException

직접 실행 호출자에 인프라 권한이 없는 경우

예제

다음 코드 예제에서는 메서드를 사용하여 SetData보안 주체 및 ID 개체 를 식별을 위해 원격 위치로 전송하는 방법을 보여 줍니다. 이 샘플에서 사용되는 클래스에 LogicalCallContextData 대한 코드를 보려면 인터페이스에 대한 예제를 ILogicalThreadAffinative 참조하세요. 이 샘플에서 사용되는 클래스에 HelloServiceClass 대한 코드를 보려면 메서드의 예제를 GetData 참조하세요. 이 샘플에서 사용되는 서버 클래스에 대한 코드를 보려면 클래스의 예제를 RegisterActivatedServiceType 참조하세요.
