从组合框获取所选对象 [英] Get selected Object from Combobox

问题描述

我有一个 Combobox 填充了对象
，然后从 combobox 中选择了某个对象想要在文本框中显示文本，但是由于某些原因，我无法通过选择来显示文本。

I have this Combobox filled with objects And Upon selecting a certain object from the combobox I would like to show Text in a Textbox, but for some reason I can't get my selection through.

这就是我的组合框中的内容：

 private void showBirds()
    {
        cboBirds.Items.Clear();
        foreach (Bird b in Bird.ReadBirdCSV(txtFile.Text))
        {
            cboBirds.Items.Add(b);
        }
    }

它基本上显示了Objects Bird中鸟类的名字

It basically shows the names of birds from the Objects Bird.

 private void cboBirds_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {

//WHAT DO I WRITE HERE TO GET txbGender TO SHOW THE GENDER?

        foreach (Bird b in cboBirds.Items)
        {
            Console.WriteLine(b.Gender +" - " + b.Name +" - " + b.Risk + " - " +b.Reference);
        }
//^This shows all info on every bird.

    }

我敢肯定这很简单，我可以

I'm sure it's really simple, I just can't seem to figure it out.

推荐答案

使用 ComboBox.SelectedIndexChanged 事件

private void ComboBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
     if(ComboBox1.SelectedItem==null) return;
     var b= (Bird) ComboBox1.SelectedItem;
     if(b!=null)
         Console.WriteLine(b.Gender +" - " + b.Name +" - " + b.Risk + " - " +b.Reference);
}
