我正在做一个程序，它将测试一架飞机是否被允许飞行。这是我第一个使用Windows窗体和C#的个人项目。我取得了很大的进步，但是，我有一个巨大的问题，我想有一个功能。我有两个窗体称为Main和FlightSetup，第二个窗体使用一个类称为AircraftClass，它包含构造函数，行为，和性质。

• • 问题**

我会尽量让它简单易懂。我在public void addaircraftButton_Click中调用类AircraftClass来创建一个对象并存储所有必要的细节，如aircraftModel，airlineName等。然而，我有一个名为aircraftList的列表框，它只显示飞机名称。详细信息取决于用户从名为detailsList的TextBox内的aircraftList中选择的内容（是的，我是这样叫它的，但它是一个文本框）。这是当问题发生时，它没有显示正确的信息，它显示了AircraftClass的属性值

• • 注**

aircraftList & detailsList在Main表单里面-我确实知道这里有一些明显的错误，但我还在学习，请对我宽容点：（
Main表单内的变量

int planeCount = 0; int tailNumber = 0; int planeIndex;
        string planeModel = "NONE"; string airline = "NONE";
        double distanceM = 0.0; double fuelG = 0.0; double maxKG = 0.0; double totalKG = 0.0;
        int passengers= 0; int bag1=0; int bag2 = 0;

主代码（仅限addbuttom方法）

public void addaircraftButton_Click(object sender, EventArgs e)
        {

            FlightSetup addAircraft = new FlightSetup(); //CREATES INFO INSIDE DETAILS

            string nl = "\r\n";

            using (addAircraft)
            {
                DialogResult result = addAircraft.ShowDialog();

                planeModel = addAircraft.planeModel_textbox.Text;
                airline = addAircraft.airline_textbox.Text;

                tailNumber = int.Parse(addAircraft.tailno_textbox.Text);
                passengers= int.Parse(addAircraft.passengerTextBox.Text);
                bag1 = int.Parse(addAircraft.carryonTextBox.Text);
                bag2= int.Parse(addAircraft.checkedBagsTextBox.Text);

                distanceM = double.Parse(addAircraft.distance_textbox.Text);
                fuelG = double.Parse(addAircraft.fuel_textbox.Text);
                maxKG = double.Parse(addAircraft.maxweight_textbox.Text);

                AircraftDetails test = new AircraftDetails(planeModel,airline,tailNumber,passengers,bag1,bag2,distanceM,fuelG,maxKG,totalKG);
                test.AircraftModel = addAircraft.planeModel_textbox.Text;
                MessageBox.Show("Flight Setup is COMPLETED! \n\nPerfom Unit Testing For Take-Off Permission", "FLIGHT SAVED!");

                planeCount++;
                noaircraft_label.Text = planeCount.ToString();
                aircraftList.Items.Add(planeModel + " - REGULAR ROLE");
            }

        }

主代码（仅限aircraftList方法）

public void aircraftList_SelectedIndexChanged(object sender, EventArgs e) //PENDING SOLUTION
        {
            AircraftDetails getData = new AircraftDetails();
            StringBuilder insertData = new StringBuilder(String.Empty);
            string nl = "\r\n";

            planeIndex = aircraftList.SelectedIndex;

            if (planeIndex > -1)
            {
                insertData.Append(getData.AircraftModel.ToString());
                insertData.Append(nl);

                detailsList.Text = insertData.ToString();
            }
        }
