C＃-从ComboBox对象属性获取int值

Question

I'm using Windows Forms. Is there way to get new_object.number_prop value from the object currently selected in comboBox1 ? Preferably without using the comboBox1 indexes. Any help would be greatly appreciated. I've been looking for a solution for a while now.

sampleObject new_object = new sampleObject();
new_object.text_prop = "sample text";
new_object.number_prop = 3;

comboBox1.Items.Insert(0, new_object);

class sampleObject
{
    public string text_prop {get; set; }
    public int number_prop {get; set; }
    public override string ToString();
    {
        return text_prop;
    }
}

Answer 1

Probably you are talking about this:

var selectedObject = (sampleObject) comboBox1.SelectedItem;
var value = selectedObject.number_prop;

Also please note, that object is reserved word (as alias to Object class) in C#.

Answer 2

Your code should be like this.

object new_object = new object();
new_object.text_prop = "sample text";
new_object.number_prop = 3;

comboBox1.Items.Insert(0, new_object);
comboBox1.ValueMember = "number_prop";
comboBox1.DisplayMember = "text_prop"

class SomeObject
{
    public string text_prop {get; set; }
    public int number_prop {get; set; }
    public override string ToString();
    {
        return text_prop;
    }
}

将组合框的valueitem设置为“ number_prop”并将displayitem设置为“ text_prop”
