protected internal virtual System.Activities.Bookmark OnResolveBookmark (object[] inputs, System.ServiceModel.OperationContext operationContext, System.ServiceModel.Activities.WorkflowHostingResponseContext responseContext, out object value);

abstract member OnResolveBookmark : obj[] * System.ServiceModel.OperationContext * System.ServiceModel.Activities.WorkflowHostingResponseContext * obj -> System.Activities.Bookmark
override this.OnResolveBookmark : obj[] * System.ServiceModel.OperationContext * System.ServiceModel.Activities.WorkflowHostingResponseContext * obj -> System.Activities.Bookmark

示例

下面的示例演示如何实现 OnResolveBookmark 方法。

protected override Bookmark OnResolveBookmark(object[] inputs, OperationContext operationContext, WorkflowHostingResponseContext responseContext, out object value)
{
    Bookmark bookmark = null;
    value = null;
    if (operationContext.IncomingMessageHeaders.Action.EndsWith("ResumeBookmark"))
    {
        //bookmark name supplied by client as input to IWorkflowCreation.ResumeBookmark
        bookmark = new Bookmark((string)inputs[1]);
        //value supplied by client as argument to IWorkflowCreation.ResumezBookmark
        value = (string) inputs[2];
    }
    else
    {
        throw new NotImplementedException(operationContext.IncomingMessageHeaders.Action);
    }
    return bookmark;
}
