WorkflowHostingResponseContext 类

定义

命名空间:

System.ServiceModel.Activities

程序集:

System.ServiceModel.Activities.dll

此类与 WorkflowHostingEndpoint 类一起使用。 它用于为 WorkflowHostingEndpoint 实现所支持的请求/答复协定发送响应。

public ref class WorkflowHostingResponseContext sealed

public sealed class WorkflowHostingResponseContext

type WorkflowHostingResponseContext = class

Public NotInheritable Class WorkflowHostingResponseContext

继承

Object

WorkflowHostingResponseContext

示例

下面的示例演示如何向工作流承载终结点提供 WorkflowHostingResponseContext。

protected override WorkflowCreationContext OnGetCreationContext(object[] inputs, OperationContext operationContext, Guid instanceId, WorkflowHostingResponseContext responseContext)
{
    WorkflowCreationContext creationContext = new WorkflowCreationContext();
    if (operationContext.IncomingMessageHeaders.Action.EndsWith("Create"))
    {
        Dictionary<string, object> arguments = (Dictionary<string, object>)inputs[0];
        if (arguments != null && arguments.Count > 0)
        {
            foreach (KeyValuePair<string, object> pair in arguments)
            {
                //arguments to pass to the workflow
                creationContext.WorkflowArguments.Add(pair.Key, pair.Value);
            }
        }
        //reply to client with instanceId
        responseContext.SendResponse(instanceId, null);
    }
    else if (operationContext.IncomingMessageHeaders.Action.EndsWith("CreateWithInstanceId"))
    {
        Dictionary<string, object> arguments = (Dictionary<string, object>)inputs[0];
        if (arguments != null && arguments.Count > 0)
        {
            foreach (KeyValuePair<string, object> pair in arguments)
            {
                //arguments to pass to workflow
                creationContext.WorkflowArguments.Add(pair.Key, pair.Value);
            }
        }
    }
    else
    {
        throw new InvalidOperationException("Invalid Action: " + operationContext.IncomingMessageHeaders.Action);
    }
    return creationContext;
}

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
SendResponse(Object, Object[])	发送对发送到 WorkflowHostingEndpoint 的消息的响应。
ToString()	返回表示当前对象的字符串。 (继承自 Object)
