For Uploading Document to Sharepoint Document Library use Following function in Client Object Model:

public void UploadDocument(string siteURL, string documentListName, string documentListURL, string documentName, byte[] documentStream) {     using (ClientContext clientContext = new ClientContext(siteURL))     {         //Get Document List         List documentsList = clientContext.Web.Lists.GetByTitle(documentListName);          var fileCreationInformation = new FileCreationInformation();         //Assign to content byte[] i.e. documentStream          fileCreationInformation.Content = documentStream;         //Allow owerwrite of document          fileCreationInformation.Overwrite = true;         //Upload URL          fileCreationInformation.Url = siteURL + documentListURL + documentName;         Microsoft.SharePoint.Client.File uploadFile = documentsList.RootFolder.Files.Add(             fileCreationInformation);          //Update the metadata for a field having name "DocType"         uploadFile.ListItemAllFields["DocType"] = "Favourites";          uploadFile.ListItemAllFields.Update();         clientContext.ExecuteQuery();     } }
