Fails to Import Microsoft.SharePoint dll

I wanted to upload build files to Sharepoint. So, I tried importing Microsoft.SharePoint.dll (ver.15.0.0) under Assets/Plugins directory to use SharePoint library functions. But, errors below occured and I don't know why this kind of things happen.



I tried importing other version of dll such as ver.14.0.4762.1000 or 14.0.0 and it didn't make any error but I couldn't refer to any library functions.


The image above is the dll's import settings.
My unity version is 2020.3.40.f1 and my project's api compatibility level is .Net 4.X. Please let me know if you know to how solve this problem. Thanks.

 

Why would you include the Sharepoint.DLL? Were you instructed to do so by some tutorial or manual?

Usually those webservices have a web backend with which you have to communicate via GET/POST requests.
Check this thread.

 

No, I searched for the way to upload file to Sharepoint libarary and I found an example code (https://www.sharepointdiary.com/201...ically-upload-file-to-sharepoint-library.html). In this example, Microsoft.Sharepoint namespace is used and I thought that I should import Microsoft.Sharepoint dll. Thank you for your advice, I'll check the thread you attached.

 

As a former SharePoint Developer, this isn't going to work. You want the client side libraries not the server side libraries.

If working with SharePoint Online look at the Microsoft Graph API.
