在Powershell中创建类[Microsoft.SharePoint.WorkflowServices.WorkflowSubscription]的对象

Question

如何在powershell中创建类[Microsoft.SharePoint.WorkflowServices.WorkflowSubscription]的对象或语法

我想在Client对象模型下写入powershell

       // Creating the workflow subscription
var sub = new SP.WorkflowServices.WorkflowSubscription(context);

以上的Powershell等效？
