How to find relative URL of a document library using CSOM

Question

To upload a file using File.SaveBinaryDirect you have to know the server relative URL of the document library you're working with.

Example from MSDN :-

ClientContext clientContext = new ClientContext("http://intranet.contoso.com");
using (FileStream fileStream = new FileStream("NewDocument.docx", FileMode.Open))
{
   ClientOM.File.SaveBinaryDirect(clientContext,
            "/Shared Documents/NewDocument.docx", fileStream, true);
}

How can you determine a Document Libraries url?

Answer 1

docLib = Context.Web.Lists.GetByTitle("Your Doclib Name");

Context.Load(docLib);
Context.Load(docLib.RootFolder);
Context.ExecuteQuery();

string serverRelativeUrl = docLib.RootFolder.ServerRelativeUrl;
