我正在使用Tridion 2011的事件系统在取消发布组件时执行一些其他操作。我正在使用发现here的代码来发布相关组件。

我正在按如下方式注册我的事件处理程序:

EventSystem.Subscribe<Component, UnPublishEventArgs>(
    RemoveAndRepublish, EventPhases.Initiated);

...,而我的处理程序方法如下:
public void RemoveAndRepublish(Component cmp, UnPublishEventArgs args,
                               EventPhases phase)
{
    // ... code to locate related component, and perform required actions...

    var instruction = new PublishInstruction(cmp.Session)
    {
        DeployAt = DateTime.Now,
        RenderInstruction = new RenderInstruction(cmp.Session)
        {
            RenderMode = RenderMode.Publish
        },
        ResolveInstruction = new ResolveInstruction(cmp.Session)
        {
            IncludeComponentLinks = true
        },
        RollbackOnFailure = true,
        StartAt = DateTime.MinValue
    };

    var target = args.Targets.FirstOrDefault();

    PublishEngine.Publish(new[] {related}, instruction, new[] {target});
}

我的问题是UnPublishEventArgs.Targets属性是IList<PublishingTarget>,在运行时它实际上是List<TargetType>,我需要获取PublicationTarget对象才能调用PublishEngine.Publish(...)

我的问题是:有没有办法从UnPublish事件获取当前(un-)PublicationTarget?

谁能提供任何帮助?

最佳答案

您需要自己从TargetType中找出PublicationTarget。根据项目的TargetType和Publication,您将需要遍历PublicationTargets以查看它们是否允许您的Publication向其发布。 (最终)这将为您提供PublicationTargets的列表。不幸的是,这是很多工作:(

所有这些,您真的需要PublicationTarget吗?如果需要从相同的“发布/目标”组合重新发布或取消发布项目,则应该能够将相同的TargetType数组解析为PublishEngine.Publish(...)方法。

当我搜索文档时,在PublishEngine()上看到以下重写:

PublishEngine.Publish Method (IEnumerable<(Of <(<'IdentifiableObject>)>)>, PublishInstruction, IEnumerable<(Of <(<'TargetType>)>)>, PublishPriority)

public static ICollection<PublishTransaction> Publish(
    IEnumerable<IdentifiableObject> items,
    PublishInstruction publishInstruction,
    IEnumerable<TargetType> targetTypes,
    PublishPriority priority
)
