    On google, search for how to read pdf file using C#. You will get reference. From SharePoint perspective i guess you will need only pass the filepath and person running this programs needs to have access on that path – P S Nov 9 '16 at 6:29

I have read file from sharepoint document library and saved into local server path using following code.

using SP = Microsoft.SharePoint.Client;
ClientContext context = new ClientContext(ConfigurationManager.AppSettings["WebURL"].ToString());
Web web;
SP.List docLibName;
SP.ListItemCollection docLibColl;
SP.ListItem item;
SP.File file;
SP.CamlQuery caml = new SP.CamlQuery();

item = docLibName.GetItemById(Convert.ToInt32("Id of the document"));
file = item.File;
var fileInfo = SP.File.OpenBinaryDirect(context, item.File.ServerRelativeUrl);

Stream fs = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, file.ServerRelativeUrl).Stream;
byte[] binary = ReadFully(fs);
        if (System.IO.File.Exists("sourceFilePath"))
            using (var fileStream = System.IO.File.Create("sourceFilePath"))
            using (var fileStream = System.IO.File.Create("sourceFilePath"))
