방법: 서비스 인스턴스 만들기 제어

  • 아티클

서비스의 인스턴스 모드를 설정하면 System.ServiceModel.InstanceContext(및 연결된 사용자 정의 서비스 개체)가 만들어지는 시기를 지정할 수 있습니다. 가능한 모드에 대해서는 InstanceContextMode 열거형을 참조하세요. 동작에 대한 자세한 내용은 동작을 사용하여 런타임 구성 및 확장을 참조하세요. 작업 예제는 동작을 참조하세요.

코드를 사용하여 서비스 인스턴스 수명을 제어하려면

  1. 서비스 클래스에 ServiceBehaviorAttribute를 적용합니다.

  2. InstanceContextMode 속성을 PerCall, PerSession 또는 Single 값 중 하나로 설정합니다.

    [ServiceBehaviorAttribute(InstanceContextMode = InstanceContextMode.PerCall)]

    <ServiceBehaviorAttribute(InstanceContextMode:=InstanceContextMode.PerCall)> _
Public Class CalculatorService

예시

다음 코드 예제에서는 InstanceContextMode 특성의 ServiceBehaviorAttribute 속성을 PerCall로 설정합니다.

// Define a service contract.
[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
public interface ICalculator
{
    [OperationContract]
    double Add(double n1, double n2);
    [OperationContract]
    double Subtract(double n1, double n2);
    [OperationContract]
    double Multiply(double n1, double n2);
    [OperationContract]
    double Divide(double n1, double n2);
}

// Service class which implements the service contract.
[ServiceBehaviorAttribute(InstanceContextMode = InstanceContextMode.PerCall)]
public class CalculatorService : ICalculator
{
    public double Add(double n1, double n2)
    {
        return n1 + n2;
    }

    public double Subtract(double n1, double n2)
    {
        return n1 - n2;
    }

    public double Multiply(double n1, double n2)
    {
        return n1 * n2;
    }

    public double Divide(double n1, double n2)
    {
        return n1 / n2;
    }
}
