Question

Can I use SharePoint client object model in web part?

This code works in my console application, but in a web part it returns “The remote server returned an error: (401) Unauthorized.”

The code is:

var siteUrl = "http://www.server.com/";
var clientContext = new ClientContext(siteUrl);

var root = clientContext.Site.RootWeb;
WebCollection collWeb = root.GetSubwebsForCurrentUser(null);
clientContext.Load(root);
clientContext.Load(collWeb);
clientContext.ExecuteQuery();

The problem might be that the client context does not use the current user credentials. What should I do?

Answer 1

You add credentials to the clientContext:

System.Net.NetworkCredential cr = new System.Net.NetworkCredential("username", "password"); 

ClientContext clientContext = new ClientContext(siteURL);

clientContext.Credentials = cr;
