C# CSOM - Get authorized view url of a file

Question

Hello,

is there a way to get a authorized url of specific file stored in SharePoint Online?

I have an (win) application, that can upload files fine. Later, the file (the uniequid is stored in a database) should be show in a webbrowser control without login.

Similar to Listitem.File.GetPreAuthorizedAccessUrl(), this works?

For Example ServerRelativeUrl + accesstoken.

Login with username and password works fine. (below the Sourcecode)

"********".ToList().ForEach(c => securePassword.AppendChar(c));
                    clientContext = new ClientContext("https://mysharepoint.sharepoint.com");//Credentials.URL);
                    clientContext.Credentials = new SharePointOnlineCredentials("[email protected]", securePassword);

 

 

 

Any ideas?
