Here i will show how to upload a file using client object model in share point 2010.The location of the file has been assigned to a variable "filepath" .

string filepath=@"d:\projects\testshareupload\orderdata.doc";
ClientContext clc = new ClientContext(siteurl);
Web w = clc.Web;
FileCreationInformation Fi = new FileCreationInformation();
Fi.Content = System.IO.File.ReadAllBytes(filepath);
Fi.Url = "orderdata.doc";
List datafiles = web.Lists.GetByTitle("Files");

SPWebService sws = SPWebService.ContentService;
SPClientRequestServiceSettings SpCclientSettings = sws.ClientRequestServiceSettings;
