请帮助，我是一个完全菜鸟。但是，我正在使用一些复杂的API。
我有外部课程：
namespace IB_CSharp_RealTime_WinForms_CS
{
//! [ewrapperimpl]
public class EWrapperImpl : EWrapper
{
...
//! [historicaldata]
public virtual void historicalData(int reqId, string date, double open, double high, double low, double close, int volume, int count, double WAP, bool hasGaps)
{
Console.WriteLine("HistoricalData. "+reqId+" - Date: "+date+", Open: "+open+", High: "+high+", Low: "+low+", Close: "+close+", Volume: "+volume+", Count: "+count+", WAP: "+WAP+", HasGaps: "+hasGaps);
}
...
我有一个表格
namespace IB_CSharp_RealTime_WinForms_CS
{
public partial class Form1 : Form
{
...
如何将我的外部课程的“双重高分”传递给我的表格？ 预先谢谢你！
我的完整代码：

using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

this.lbData.Items.Add(text);
}

ibClient = new IB_CSharp_RealTime_WinForms_CS.EWrapperImpl();
}
private void Form1_Load(object sender, EventArgs e)

}
private void btnConnect_Click(object sender, EventArgs e)

var reader = new EReader(ibClient.ClientSocket, ibClient.Signal);
reader.Start();
new Thread(() => {
while (ibClient.ClientSocket.IsConnected())
{
ibClient.Signal.waitForSignal();
reader.processMsgs();
}
})
{ IsBackground = true }.Start();
while (ibClient.NextOrderId <= 0) { }
// Set up the form object in the EWrapper
ibClient.myform = (Form1)Application.OpenForms[0];
}
private void btnDisconnect_Click(object sender, EventArgs e)
{
// Disconnect from interactive Brokers
ibClient.ClientSocket.eDisconnect();
}
private void btnStart_Click(object sender, EventArgs e)
{
// Create a new contract to specify the security we are searching for
IBApi.Contract contract = new IBApi.Contract();
// Create a new TagValueList object (for API version 9.71 and later)
List < IBApi.TagValue > mktDataOptions = new List<IBApi.TagValue>();
// Set the underlying stock symbol from the tbSymbol text box
contract.Symbol = tbSymbol.Text;
// Set the Security type to STK for a Stock
contract.SecType = "STK";
// Use "SMART" as the general exchange
contract.Exchange = "SMART";
// Set the primary exchange (sometimes called Listing exchange)
// Use either NYSE or ISLAND
contract.PrimaryExch = "ISLAND";
// Set the currency to USD
contract.Currency = "USD";
// Kick off the subscription for real-time data (add the mktDataOptions list for API v9.71)
ibClient.ClientSocket.reqMktData(1, contract, "", false, mktDataOptions);
// For API v9.72 and higher, add one more parameter for regulatory snapshot
// ibClient.ClientSocket.reqMktData(1, contract, "", false, false, mktDataOptions);
} // end btnStart_Click
private void btnStop_Click(object sender, EventArgs e)
{
// Make the call to cancel the market data subscription
ibClient.ClientSocket.cancelMktData(1);
}
}
}
我想要的是TextBox1.Text以显示“ high”的值。基本上，如果我可以学习如何传递该值，则可以使用它传递所有其他值。
