如何从组合框中删除对象？ [英] How to delete object from combobox?

问题描述

我有一个组合框，其中包含 Foo 类型的对象，这是 Foo 类：

I have a combobox with objects of Foo type, here is the Foo class:

public class Foo
{
    public string name { get; set; }
    public string path { get; set; }
}

Foo.name 是组合框中显示的文本， Foo.path 是所选选项的值。

The Foo.name is the displayed text in the combobox and Foo.path is the value of the selected option.

I想要在执行一些操作后从组合框中删除一个选项。

I want to delete an option from the combobox after some operation I made.

我尝试了以下方式：

• 1

• 1

comboBox2.Items.Remove(@comboBox2.Text);  

2

2

comboBox2.Items.Remove(@comboBox2.SelectedValue.ToString());  

3

3

Foo ToDelete = new Foo();
ToDelete.name = @comboBox2.Text;
ToDelete.path = @comboBox2.SelectedValue.ToString();
comboBox2.Items.Remove(ToDelete); 

对我来说没有任何用。 ：/如何执行？

更新

这就是我的方法m初始化组合框：

This is how I'm initializing my combobox:

    string[] filePaths = Directory.GetFiles(sites.paths[comboBox1.SelectedIndex]);

        List<Foo> combo2data = new List<Foo>();

        foreach (string s in filePaths)
        {
            Foo fileInsert = new Foo();
            fileInsert.path = s;
            fileInsert.name = Path.GetFileName(s);
            combo2data.Add(fileInsert);
        }

        comboBox2.DataSource = combo2data;
        comboBox2.ValueMember = "path";
        comboBox2.DisplayMember = "name";

推荐答案

comboBox2.Items.Remove（comboBox2.SelectedValue）;只会从组合框中删除，而不会从绑定到组合框中的数据源中删除。您可以将其从数据源中删除，然后重新绑定该数据源。

comboBox2.Items.Remove(comboBox2.SelectedValue); will only remove from the combobox, not from the datasource bound to the combobox. You may remove it from the datasource and re-bind the datasource.
