(C# UWP/WinRT) SharePoint -- Upload File

Demonstrates how to upload a file to a SharePoint folder.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// -------------------------------------------------------------------------
// The following comments apply to SharePoint Windows classic authentication.
// -------------------------------------------------------------------------
// For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
// The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
// The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
// Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
// for example, "chilkat" instead of "chilkat@mycompany.com"

Chilkat.Http http = new Chilkat.Http();

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = true;

// -------------------------------------------------------------------------
// The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
// If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
// establish the cookie as shown at SharePoint Online Authentication
// -------------------------------------------------------------------------

// When creating, updating, and deleting SharePoint entities, we'll need
// to first get the server's form digest value to send in the X-RequestDigest header.
// This can be retrieved by making a POST request with an empty body to
// http://<site url>/_api/contextinfo and extracting the value of the
// d:FormDigestValue node in the XML that the contextinfo endpoint returns.

// If your Sharepoint site is within a site collection, then use "https://SHAREPOINT_HTTPS_DOMAIN/sites/teamA/_api/contextinfo" where "teamA" is the name of the site.
Chilkat.HttpResponse resp = await http.PostXmlAsync("https://SHAREPOINT_HTTPS_DOMAIN/_api/contextinfo","","utf-8");
