In this blog, we will see the steps involved in updating the date field in SharePoint list in Office 365, using CSOM.

  1. var login = "[email protected]";
  2. var password = "your password"
  4. var securePassword = new SecureString();
  6. foreach (char c in password)
  7. {
  8. securePassword.AppendChar(c);
  9. }
  10. SharePointOnlineCredentials onlineCredentials = new SharePointOnlineCredentials(login, securePassword);
  12. ClientContext context = new ClientContext(SiteURL);
  13. context.Credentials = onlineCredentials;
  14. List list = context.Web.Lists.GetByTitle("startupListList");
  15. ListItem oListItem = list.GetItemById(1);
  17. oListItem["StartupDate"] = DateTime.UtcNow;
  19. oListItem.Update();
  21. context.ExecuteQuery();
  22. }
