AspNetCompatibilityRequirementsAttribute.RequirementsMode 属性

定义

命名空间:

System.ServiceModel.Activation

程序集:

System.ServiceModel.dll

获取或设置服务所需的 ASP.NET 兼容性级别。

public:
 property System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode RequirementsMode { System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode get(); void set(System::ServiceModel::Activation::AspNetCompatibilityRequirementsMode value); };

public System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode RequirementsMode { get; set; }

member this.RequirementsMode : System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode with get, set

Public Property RequirementsMode As AspNetCompatibilityRequirementsMode

属性值

AspNetCompatibilityRequirementsMode

指示 AspNetCompatibilityRequirementsMode 服务所需的 ASP.NET 兼容性程度的 。 默认值是 Allowed。

例外

InvalidEnumArgumentException

该值不是 AspNetCompatibilityRequirementsModeenum 的有效值。

示例

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class CalculatorService : ICalculatorSession
{
    double result
    {   // Store result in AspNet session.
        get
        {

                return (double)HttpContext.Current.Session["Result"];
            return 0.0D;
        }

注解

使用 RequirementsMode 属性可以在代码中设置宿主模式。 还可以通过设置应用程序级配置标记 aspNetCompatibilityEnabled 来完成此操作。 有关详细信息，请参阅 <serviceHostingEnvironment>。

在运行时，应用程序可以通过检查静态属性 AspNetCompatibilityEnabled的值来检测是否启用了 ASP.NET 兼容模式。
