看看列表/文档库的事件接收器。对象模型中内置了同步和异步选项。(ItemAdded, ItemAdding, ItemUpdated, ItemUpdating … 等等。)

The following site should give you a good start: http://www.davehunter.co.uk/Blog/Lists/Posts/Post.aspx?List=f0e16a1a%2D6fa9%2D4130%2Dbcab%2Dbaeb97ccc4ff&ID=69

That depends whether you need to react to these events immediately or if you can gather them later. For immediate actions event receivers would be the best option but you have to prepare them for each action type you want to handle. For the latter, you can use audit log. That s a feature in sharepoint, that gathers information about user actions. This will require enabling some features on sites and maybe some configuration where you can specify which actions should be logged).

Unfortunately I m not sure if it s possible to get this data using CSOM - according to answer from the link below, you ll have to use server solution: https://social.msdn.microsoft.com/Forums/office/en-US/fd628034-9d6d-4f98-afb8-1d0bd6926bd0/accessing-audit-logs-using-csom-in-sharepoint-2013?forum=sharepointdevelopment
