你可以使用泛型类型:

public class ComboBoxItem<T>
{
    private string Text { get; set; }
    public T Value { get; set; }

    public override string ToString()
    {
        return Text;
    }

    public ComboBoxItem(string text, T value)
    {
        Text = text;
        Value = value;
    }
}

使用简单int-Type的示例:

private void Fill(ComboBox comboBox)
    {
        comboBox.Items.Clear();
        object[] list =
            {
                new ComboBoxItem<int>("Architekt", 1),
                new ComboBoxItem<int>("Bauträger", 2),
                new ComboBoxItem<int>("Fachbetrieb/Installateur", 3),
                new ComboBoxItem<int>("GC-Haus", 5),
                new ComboBoxItem<int>("Ingenieur-/Planungsbüro", 9),
                new ComboBoxItem<int>("Wowi", 17),
                new ComboBoxItem<int>("Endverbraucher", 19)
            };

        comboBox.Items.AddRange(list);
    }

你可以像这样使用匿名类:

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

comboBox.Items.Add(new { Text = "report A", Value = "reportA" });
comboBox.Items.Add(new { Text = "report B", Value = "reportB" });
comboBox.Items.Add(new { Text = "report C", Value = "reportC" });
comboBox.Items.Add(new { Text = "report D", Value = "reportD" });
comboBox.Items.Add(new { Text = "report E", Value = "reportE" });

更新:虽然上面的代码将正确显示在组合框中，你将不能使用组合框的SelectedValue或SelectedText属性。为了能够使用这些，绑定组合框如下:

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

var items = new[] { 
    new { Text = "report A", Value = "reportA" }, 
    new { Text = "report B", Value = "reportB" }, 
    new { Text = "report C", Value = "reportC" },
    new { Text = "report D", Value = "reportD" },
    new { Text = "report E", Value = "reportE" }
};

comboBox.DataSource = items;

我喜欢fab的答案，但不想为我的情况使用字典，所以我替换了一个元组列表。

// set up your data
public static List<Tuple<string, string>> List = new List<Tuple<string, string>>
{
  new Tuple<string, string>("Item1", "Item2")
}

// bind to the combo box
comboBox.DataSource = new BindingSource(List, null);
comboBox.ValueMember = "Item1";
comboBox.DisplayMember = "Item2";

//Get selected value
string value = ((Tuple<string, string>)queryList.SelectedItem).Item1;

这里有更好的解决方案;

Dictionary<int, string> userListDictionary = new Dictionary<int, string>();
        foreach (var user in users)
        {
            userListDictionary.Add(user.Id,user.Name);
        }

        cmbUser.DataSource = new BindingSource(userListDictionary, null);
        cmbUser.DisplayMember = "Value";
        cmbUser.ValueMember = "Key";

检索数据

MessageBox.Show(cmbUser.SelectedValue.ToString());

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"/>

如果有人仍然对此感兴趣，这里有一个简单而灵活的类，用于具有文本和任何类型的值的组合框项目(非常类似于Adam Markowitz的例子):

public class ComboBoxItem<T>
{
    public string Name;
    public T value = default(T);

    public ComboBoxItem(string Name, T value)
    {
        this.Name = Name;
        this.value = value;
    }

    public override string ToString()
    {
        return Name;
    }
}

使用<T>比将值声明为对象要好，因为使用object，您必须跟踪用于每个项的类型，并在代码中强制转换以正确使用它。

我已经在我的项目中使用了很长一段时间了。它真的很方便。
