AspNetCompatibilityRequirementsMode 枚举

定义

命名空间:

System.ServiceModel.Activation

程序集:

System.ServiceModel.dll

指定 Windows Communication Foundation (WCF) 服务是否以与 ASP.NET 兼容的模式运行或是否可以运行。

public enum class AspNetCompatibilityRequirementsMode

public enum AspNetCompatibilityRequirementsMode

type AspNetCompatibilityRequirementsMode = 

Public Enum AspNetCompatibilityRequirementsMode

继承

Object

ValueType

Enum

AspNetCompatibilityRequirementsMode

字段

Allowed	1	WCF 服务可以在应用程序域中运行，ASP.NET 兼容模式设置为true或设置为 。false
NotAllowed	0	WCF 服务必须在应用程序域中运行，ASP.NET 兼容模式设置为 false。
Required	2	WCF 服务必须在应用程序域中运行，ASP.NET 兼容模式设置为 true。

示例

服务开发人员可以通过将AspNetCompatibilityRequirementsAttribute.RequirementsMode属性设置为 Required 来确保其服务仅在 ASP.NET 兼容模式下运行，如以下示例所示：

[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
public interface ICalculatorSession
{
    [OperationContract]
    void Clear();
    [OperationContract]
    void AddTo(double n);
    [OperationContract]
    void SubtractFrom(double n);
    [OperationContract]
    void MultiplyBy(double n);
    [OperationContract]
    void DivideBy(double n);
    [OperationContract]
    double Equals();
}

<ServiceContract(Namespace:="http://Microsoft.ServiceModel.Samples")> _
Public Interface ICalculatorSession

    <OperationContract()> _
    Sub Clear()
    <OperationContract()> _
    Sub AddTo(ByVal n As Double)
    <OperationContract()> _
    Sub SubtractFrom(ByVal n As Double)
    <OperationContract()> _
    Sub MultiplyBy(ByVal n As Double)
    <OperationContract()> _
    Sub DivideBy(ByVal n As Double)
    <OperationContract()> _
    Function Equal() As Double
End Interface

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class CalculatorService : ICalculatorSession
{
    double result
    {   // Store result in AspNet session.
        get
        {
            if (HttpContext.Current.Session["Result"] != null)
                return (double)HttpContext.Current.Session["Result"];
            return 0.0D;
        }
        set
        {
            HttpContext.Current.Session["Result"] = value;
        }
    }

    public void Clear()
    {
    }

    public void AddTo(double n)
    {
        result += n;
    }

    public void SubtractFrom(double n)
    {
        result -= n;
    }

    public void MultiplyBy(double n)
    {
        result *= n;
    }

    public void DivideBy(double n)
    {
        result /= n;
    }

    public double Equals()
    {
        return result;
    }
}

    <AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Required)> _
    Public Class CalculatorService
        Implements ICalculatorSession

        Property Result() As Double
            ' Store result in AspNet Session.
            Get
                If (HttpContext.Current.Session("Result") Is Nothing) Then
                    Return 0D
                End If
                Return HttpContext.Current.Session("Result")
            End Get
            Set(ByVal value As Double)
                HttpContext.Current.Session("Result") = value
            End Set
        End Property

        Public Sub Clear() _
 Implements ICalculatorSession.Clear
            Result = 0D
        End Sub

        Public Sub AddTo(ByVal n As Double) _
Implements ICalculatorSession.AddTo
            Result += n
        End Sub

        Public Sub SubtractFrom(ByVal n As Double) _
Implements ICalculatorSession.SubtractFrom

            Result -= n
        End Sub

        Public Sub MultiplyBy(ByVal n As Double) _
Implements ICalculatorSession.MultiplyBy

            Result *= n
        End Sub

        Public Sub DivideBy(ByVal n As Double) _
Implements ICalculatorSession.DivideBy

            Result /= n
        End Sub

        Public Function Equal() As Double _
Implements ICalculatorSession.Equal

            Return Result
        End Function
    End Class

注解

ASP.NET 兼容模式允许 WCF 服务使用 ASP 功能，例如标识模拟。 该服务是通过 Web.config 文件在应用程序级别启用的，并且无法由嵌套在应用程序中的 Web.config 文件重写。 AspNetCompatibilityRequirementsMode如果未为服务指定值，则默认值为 Allowed。 有关详细信息，请参阅 <serviceHostingEnvironment>。
