I'm going to write a lot of code that works with SharePoint lists and libraries over REST and C# (HttpClient)

I want to create or find helper classes that help me do the following tasks over REST:

  • Get all list items (preferably in nice C# objects with all SP properties)
  • Get item/file by list ID
  • Get items using CAML
  • Delete item/file by ID
  • Update item/file
  • Create folder
  • Upload a file
  • Add List item

Is there a project/library you can recommend I can reuse so that I don't write all these things myself?

Additional info:

  • CSOM (ClientContext) is not an option
  • There are a lot of samples with REST online, but they are too messy
  • I did some googling, but could not find one good Library/Project online that does all these things in a way I want
  • Preferably, I want this library/project to use HttpClient class

    Re: "There are a lot of samples with REST online, but they are too messy". That's because using the REST API in C# is messy. You have to deal with raw XML or raw JSON. In my opinion you're much better off using the Client Object Model. – Rob Windsor Apr 10 '16 at 21:05
  • agree, except for the fact that I cannot use CSOM. I have to deal with Xamarin and Windows Phone SDK. you cannot use CSOM with Xamarin. And I cannot aithenticate via CSOM in Wndows Phone apps because of ADFS – Denis Molodtsov Apr 10 '16 at 21:24
  • if you can get it working with raw json ( returning specifically ) then the guide made by rob is perfect link – Raoul Mensink Apr 11 '16 at 8:53

(I must say it is embarrassing to admit this) I have (partially) done this with REST.

I had used Newtonsoft.Json to parse the responses and HttpWebRequests to interact with the REST API. (I think you would be able to work with Atom using System.Xml as well.)

However I am not aware of a single library doing the process end-to-end.

    I'm in a long process of creating CSOM-like classes that work via REST. it's actually a lot of fun. Here is an example: Authenticator aithenticator = new Authenticator(Login, password, siteUrl); XContext context = await aithenticator.GetCookiesAndDigest(); XList list = await context.GetList("Photos"); List<XListItem> listItems = await list.GetItems(caml); await listItems[0].Delete(); – Denis Molodtsov Apr 20 '16 at 2:21
  • That does make sense. After all you could then reuse your code in future projects! Good luck :) – Nisarg Apr 20 '16 at 8:32

I've uploaded a sample XSOM project here

The code will look like so: enter image description here

There are some basic operations available, but it's a good start
