eg:MT4就運(yùn)用DDE讓自己成為服務(wù)端，程序可利用DDE獲取MT4的外匯報(bào)價(jià)數(shù)據(jù)實(shí)現(xiàn)實(shí)時(shí)更新。

?? 先下載MT4運(yùn)行，設(shè)置工具-選項(xiàng)-勾選啟用為DDE服務(wù)器

using?NDde.Client;??

public static DdeClient Create(string Symbol,string data, Action<DdeAdviseEventArgs> handler) ??????? { ??????????? DdeClient client = null; ??????????? try ??????????? { ??????????????? //申明并實(shí)例化一個(gè)DdeClient對(duì)象? ? ??????????????? client = new DdeClient("MT4", data); ??????????????? client.Advise += (o, a) => { handler(a); }; ??????????????? //連接到DDE服務(wù)器? ? ??????????????? client.Connect(); ??????????????? //循環(huán)獲取數(shù)據(jù)? ? ??????????????? client.StartAdvise(Symbol, 1, true, 10000); ??????????? } ??????????? catch (Exception ex) ??????????? { ??????????????? return null; ??????????? } ??????????? return client; ??????? }

//調(diào)用

?????? DdeClient high_client = Create("EURUSD", "Quote",
??????????????? d =>
??????????????? {
??????????????????? Console.WriteLine(d.Text);
??????????????? }
??????????? );
??????????? Console.ReadKey();
