This is a small code snippet on how to add a content type to a site and how to install an app(or these days an Add-In). Notice that adding an app this way is not the recommended way. This is “cheating”, well the recommended way to add an app to a production environment is through a app catalog or a store BUT if you do need to add it for some reason through CSOM well this is the way. You could also apply the same technique to PowerShell:
private static void EnsureDeveloperFeature(ClientContext ctx)
{
var result = ctx.LoadQuery(ctx.Site.Features.Where(f => f.DefinitionId == DeveloperFeatureId));
ctx.ExecuteQuery();
if (result.Any()) return;
var feature = ctx.Site.Features.Add(DeveloperFeatureId, true, FeatureDefinitionScope.None);
ctx.ExecuteQuery();
}
private static void DeleteDeveloperFeature(ClientContext ctx)
{
var result = ctx.LoadQuery(ctx.Site.Features.Where(f => f.DefinitionId == DeveloperFeatureId));
ctx.ExecuteQuery();
if (!result.Any()) return;
ctx.Site.Features.Remove(DeveloperFeatureId, true);
ctx.ExecuteQuery();
}
private static void EnsureContentTypeAndRibbonApp(ClientContext ctxWorkspace, string administratorsEmail)
{
try
{
var contentTypeName = ConfigurationManager.AppSettings["ContentTypeName"].ToString();
var appFullPath = ConfigurationManager.AppSettings["RibbonAppFullPath"].ToString();
if (String.IsNullOrEmpty(contentTypeName) && String.IsNullOrEmpty(appFullPath))
return;
Web currentWeb = ctxWorkspace.Web;
ctxWorkspace.Load(currentWeb);
var webContentTypes = currentWeb.ContentTypes;
ctxWorkspace.Load(webContentTypes);
var apps = currentWeb.GetAppInstances();
ctxWorkspace.Load(apps);
ctxWorkspace.ExecuteQuery();
// Install the ribbon achieving ribbon app if the app file exists and does not exist already
if (System.IO.File.Exists(appFullPath) && apps.SingleOrDefault(o => o.Title.Contains(ConfigurationManager.AppSettings["ArchivingRibbonAppName"].ToString())) == null)
{
EnsureDeveloperFeature(ctxWorkspace);
using (var packageStream = System.IO.File.OpenRead(appFullPath))
{
var appInstance = ctxWorkspace.Web.LoadAndInstallApp(packageStream);
ctxWorkspace.Load(appInstance);
ctxWorkspace.ExecuteQuery();
if (appInstance != null && appInstance.Status == AppInstanceStatus.Initialized)
{
Console.WriteLine("App was installed on:" + currentWeb.Url);
}
}
DeleteDeveloperFeature(ctxWorkspace);
}
var contentType = webContentTypes.SingleOrDefault(o => o.Name.Contains(contentTypeName));
if(contentType != null)
{
ctxWorkspace.Load(contentType);
ctxWorkspace.ExecuteQuery();
ListCollection lists = ctxWorkspace.Web.Lists;
var sourceWeb = ctxWorkspace.Web;
ctxWorkspace.Load(sourceWeb);
ctxWorkspace.Load(lists);
ctxWorkspace.ExecuteQuery();
foreach (List list in lists.Where(o => o.BaseType == BaseType.DocumentLibrary))
{
if (list.Hidden || list.IsApplicationList || list.IsCatalog)
continue;
// Check for existing content types only if content type management is set to active
if (list.ContentTypesEnabled)
{
var listCTs = list.ContentTypes;
ctxWorkspace.Load(listCTs);
ctxWorkspace.ExecuteQuery();
if (listCTs.SingleOrDefault(o => o.Name == contentType.Name) != null)
continue;
}
list.ContentTypesEnabled = true;
list.Update();
ctxWorkspace.ExecuteQuery();
list.ContentTypes.AddExistingContentType(contentType);
list.Update();
ctxWorkspace.ExecuteQuery();
}
}
}
catch (Exception ex)
{
}
}
