c# - Class defined Datatable, how to leave row [0] unchanged? -

-

i add rows table configs this, form want

            datarow row2 = dataaccess.instance.configs.newrow();             row2["nome"] = "abrirficheiro";             row2["valor"] = convert.tostring(variables.abrirficheiro);             dataaccess.instance.configs.rows.add(row2);

but wanna keep row @ index 0 (the first one) untouched, idea how it's done? edit: i've been working around past hour, still unsucessful

the table class code this

public sealed class dataaccess {     static readonly dataaccess instance = new dataaccess();       //**adicionar tabelas aqui     public datatable configs { get; private set; }       // explicit static constructor tell c# compiler     // not mark type beforefieldinit     static dataaccess()     {     }      dataaccess()     {          this.configs = new datatable("configs");           tabelasset.tables.add("configs");          configs.columns.add("nome");         configs.columns.add("valor");     }      public static dataaccess instance     {                 {             return instance;         }     } }

solved: modified code way

            datarow row2 = dataaccess.instance.configs.newrow();             row2["nome"] = "abrirficheiro";             row2["valor"] = convert.tostring(variables.abrirficheiro);             dataaccess.instance.configs.rows.insertat(row2, 2);              dataaccess.instance.configs.rows.removeat(1);               //second set             datarow row3 = dataaccess.instance.configs.newrow();             row3["nome"] = "mantergravacao";             row3["valor"] = convert.tostring(variables.mantergravacao);             dataaccess.instance.configs.rows.insertat(row3, 3);              dataaccess.instance.configs.rows.removeat(2);

and on, basicaly, gotta insert first, remove, i'm sure there other ways has been working flawlessly

  dataaccess.instance.configs.rows.insertat(row2,1)

i'm working in node js , i'm trying send array, clients, server every client normal emit, keeps giving me error: data = json.stringify(ev); typeerror: converting circular structure json shortly, do. var clients = new array(); io.sockets.on('connection', function(socket) { clients.push(socket); socket.on('loginuser', function(data){ io.sockets.emit("getusers", clients); }); i've seen couple of other people having problem, answers didn't work out me. looking @ bigger problem, can't send array of sockets client side. sockets objects make sense in current context/process. if want control sockets client side, instead add sort of rpc functionality.
