CSOM Example

Once I was asked to develop a solution that was not to be installed on the SharePoint server neither I was allowed to create a webpart solution that could be deployed on SharePoint server. The best solution that I found was to create Desktop Application, and delivering it executable file.

As it was a desktop application we need to use CSOM. In this blog I will show you a basic code demo to interact with SharePoint server.

Validate User

1.       When you are on same domain as SharePoint server and use windows credentials to login.

using (ClientContext ctx = new ClientContext(URL))

{

}

2.       When you are in different domain or want to login as different user.

using (ClientContext ctx = new ClientContext(URL))

{

  ctx.Credentials = new NetworkCredential(UserName,Password,Domain);

}

3.  When you want to login as FBA User

using (ClientContext ctx = new ClientContext(URL))

{

  ctx.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;

                            ctx.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo(UserName, Password);

}

Query for Sites

 Add below code on authentication success.

     ctx.Load(ctx.Site); // Query for Web

     ctx.ExecuteQuery(); // Execute

     Site oSite = ctx.Site;

     Web rootWeb = ctx.Site.RootWeb;

Query for Lists/Libraries

                 ctx.Load(rootWeb);

      ctx.ExecuteQuery();

      List list = null;

      try

      {

        list = rootWeb.Lists.GetByTitle(ListName);

        ctx.Load(list, tList => tList.Title);

        ctx.ExecuteQuery();

      }

      catch (Exception e)

      {

      }
