Sharepoint CSOM LoadQuery method to store the return value in another collection, rather than use the web.Lists property

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

// Retrieve all lists from the server, and put the return value in another 
// collection instead of the web.Lists. 
IEnumerable<SP.List> result = context.LoadQuery(web.Lists.Include( // For each list, retrieve Title and Id.
                                                                   list => list.Title, 
                                                                   list => list.Id)); 

// Execute query. 
context.ExecuteQuery(); 

// Enumerate the result. 
foreach (List list in web.Lists) 
{ 
    label1.Text = label1.Text + ", " + list.Title; 
} 

Sharepoint CSOM Retrieve all SharePoint lists in a web

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

// Retrieve all lists from the server. 
context.Load(web.Lists, 
             lists => lists.Include(list => list.Title, // For each list, retrieve Title and Id. 
                                    list => list.Id)); 

// Execute query. 
context.ExecuteQuery(); 

// Enumerate the web.Lists. 
foreach (List list in web.Lists) 
{ 
    label1.Text = label1.Text + ", " + list.Title; 
} 

Sharepoint CSOM Create a new SharePoint website

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

WebCreationInformation creation = new WebCreationInformation(); 
creation.Url = "web1"; 
creation.Title = "Hello web1"; 
Web newWeb = context.Web.Webs.Add(creation); 

// Retrieve the new web information. 
context.Load(newWeb, w => w.Title); 
context.ExecuteQuery(); 

label1.Text = newWeb.Title; 

Sharepoint CSOM Write to website's properties

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

web.Title = "New Title"; 
web.Description = "New Description"; 

// Note that the web.Update() does not trigger a request to the server
// because the client library until ExecuteQuery() is called. 
web.Update(); 

// Execute the query to server.
context.ExecuteQuery(); 

Sharepoint CSOM Retrieve only selected properties of a website

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

// We want to retrieve the web's title and description. 
context.Load(web, w => w.Title, w => w.Description); 

// Execute the query to server.
context.ExecuteQuery(); 

// Now, only the web's title and description are available. If you 
// try to print out other properties, the code will throw 
// an exception because other properties are not available. 
label1.Text = web.Title;
label1.Text = web. Description;

Sharepoint CSOM Retrieve the title of a SharePoint website.

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// The SharePoint web at the URL.
Web web = context.Web; 

// We want to retrieve the web's properties.
context.Load(web); 

// Execute the query to the server.
context.ExecuteQuery(); 

// Now, the web's properties are available and we could display 
// web properties, such as title. 
label1.Text = web.Title;

Basic operations with the SharePoint .NET client object model

When you create an App for SharePoint 2013 project in Visual Studio 2012, references to the .NET Framework assemblies,Microsoft.SharePoint.Client.Runtime.dll and Microsoft.SharePoint.Client.dll, are automatically added to the project.

The files are located on any SharePoint 2013 server at %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\15\ISAPI.
