Read items from list in host-web from provider-hosted app

I have a provider hosted app. and I'm trying to get to the listitems in a list that is on my host-web.

I can get a list of all the lists I have. But when I try to get to the listitems, it's always empty.

var spContext = SharePointContextProvider.Current.GetSharePointContext(Context);

            using (var clientContext = spContext.CreateUserClientContextForSPHost())
            {
                clientContext.Load(clientContext.Web, web => web.Title);
                clientContext.ExecuteQuery();

                ListCollection lists = clientContext.Web.Lists;
                List list = lists.GetByTitle("TestList");

                CamlQuery camlQuery = new CamlQuery();
                camlQuery.ViewXml = "<View><RowLimit>100</RowLimit></View>";
                Microsoft.SharePoint.Client.ListItemCollection items = list.GetItems(camlQuery);
                clientContext.Load<ListCollection>(lists);
                clientContext.Load<List>(list);
                clientContext.Load<Microsoft.SharePoint.Client.ListItemCollection>(items);

                clientContext.ExecuteQuery();
                foreach (Microsoft.SharePoint.Client.ListItem item in items)
                {
                    Response.Write("<br />" + item.FieldValues["Title"]);
                }
            }

In the AppManifest.xml i added a 'full control' permission for list

Your code is perfectly fine ....

Just you have to make change in "AppManifest.xml" file permission give site collection as full control as you are using host web .

Apparently I did everything correct. When installing I still had to say which lists it had full control on.
