// Bind combobox to dictionary
Dictionary<string, string>test = new Dictionary<string, string>();
        test.Add("1", "dfdfdf");
        test.Add("2", "dfdfdf");
        test.Add("3", "dfdfdf");
        comboBox1.DataSource = new BindingSource(test, null);
        comboBox1.DisplayMember = "Value";
        comboBox1.ValueMember = "Key";

// Get combobox selection (in handler)
string value = ((KeyValuePair<string, string>)comboBox1.SelectedItem).Value;

// Bind combobox to dictionary
Dictionary<string, string>test = new Dictionary<string, string>();
        test.Add("1", "dfdfdf");
        test.Add("2", "dfdfdf");
        test.Add("3", "dfdfdf");
        comboBox1.DataSource = new BindingSource(test, null);
        comboBox1.DisplayMember = "Value";
        comboBox1.ValueMember = "Key";

// Get combobox selection (in handler)
string value = ((KeyValuePair<string, string>)comboBox1.SelectedItem).Value;

Visual Studio 2013是这样做的:

单一项目:

comboBox1->Items->AddRange(gcnew cli::array< System::Object^  >(1) { L"Combo Item 1" });

多个项目:

comboBox1->Items->AddRange(gcnew cli::array< System::Object^  >(3)
{
    L"Combo Item 1",
    L"Combo Item 2",
    L"Combo Item 3"
});

不需要重写类或包含任何其他内容。是的，comboBox1->SelectedItem和comboBox1->SelectedIndex调用仍然有效。

类创造:

namespace WindowsFormsApplication1
{
    class select
    {
        public string Text { get; set; }
        public string Value { get; set; }
    }
}

Form1代码:

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            List<select> sl = new List<select>();
            sl.Add(new select() { Text = "", Value = "" });
            sl.Add(new select() { Text = "AAA", Value = "aa" });
            sl.Add(new select() { Text = "BBB", Value = "bb" });
            comboBox1.DataSource = sl;
            comboBox1.DisplayMember = "Text";
        }

        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

            select sl1 = comboBox1.SelectedItem as select;
            t1.Text = Convert.ToString(sl1.Value);

        }

    }
}

您可以使用此代码将一些项插入到具有文本和值的组合框中。

C#

private void ComboBox_SelectionChanged_1(object sender, SelectionChangedEventArgs e)
{
    combox.Items.Insert(0, "Copenhagen");
    combox.Items.Insert(1, "Tokyo");
    combox.Items.Insert(2, "Japan");
    combox.Items.Insert(0, "India");   
}

XAML

<ComboBox x:Name="combox" SelectionChanged="ComboBox_SelectionChanged_1"/>

您应该在运行时使用动态对象来解析组合框项。

comboBox.DisplayMember = "Text";
comboBox.ValueMember = "Value";

comboBox.Items.Add(new { Text = "Text", Value = "Value" });

(comboBox.SelectedItem as dynamic).Value
