QueryCorrelationInitializer 类

定义

命名空间:

System.ServiceModel.Activities

程序集:

System.ServiceModel.Activities.dll

在发送或接收消息时，基于 CorrelationHandle 的结果初始化关联的 MessageQuerySet。

public ref class QueryCorrelationInitializer sealed : System::ServiceModel::Activities::CorrelationInitializer

[System.Windows.Markup.ContentProperty("MessageQuerySet")]
public sealed class QueryCorrelationInitializer : System.ServiceModel.Activities.CorrelationInitializer

[<System.Windows.Markup.ContentProperty("MessageQuerySet")>]
type QueryCorrelationInitializer = class
    inherit CorrelationInitializer

Public NotInheritable Class QueryCorrelationInitializer
Inherits CorrelationInitializer

继承

Object

属性

ContentPropertyAttribute

示例

下面的示例演示如何使用 QueryCorrelationInitializer 类设置 SendReply 活动的相关初始值设定项。

new SendReply
{
    DisplayName = "Send Adjusted Cost",
    Request = prescriptionRequest,
    // Initialize the orderHandle using the MessageQuerySet to correlate with the final GetAdjustedCost request
    CorrelationInitializers = 
    {
        new QueryCorrelationInitializer
        {
            CorrelationHandle = orderHandle,
            MessageQuerySet = GetOrderQuerySet
        }
    },
    Content = SendContent.Create(new InArgument<Order>((e) => order.Get(e)))
}

构造函数

QueryCorrelationInitializer()

初始化 QueryCorrelationInitializer 类的新实例。
