ComboBox:向项目添加文本和值(无绑定源) [英] ComboBox: Adding Text and Value to an Item (no Binding Source)

问题描述

在 C# WinApp 中，如何将 Text 和 Value 添加到 ComboBox 的项目中?我做了一个搜索，通常答案是使用绑定到源"..但就我而言，我的程序中没有准备好绑定源......我该如何做这样的事情:

In C# WinApp, how can I add both Text and Value to the items of my ComboBox? I did a search and usually the answers are using "Binding to a source".. but in my case I do not have a binding source ready in my program... How can I do something like this:

combo1.Item[1] = "DisplayText";
combo1.Item[1].Value = "useful Value"

推荐答案

您必须创建自己的类类型并覆盖 ToString() 方法以返回您想要的文本.下面是一个您可以使用的类的简单示例:

You must create your own class type and override the ToString() method to return the text you want. Here is a simple example of a class you can use:

public class ComboboxItem
{
    public string Text { get; set; }
    public object Value { get; set; }

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

以下是其用法的简单示例:

The following is a simple example of its usage:

private void Test()
{
    ComboboxItem item = new ComboboxItem();
    item.Text = "Item text1";
    item.Value = 12;

    comboBox1.Items.Add(item);

    comboBox1.SelectedIndex = 0;

    MessageBox.Show((comboBox1.SelectedItem as ComboboxItem).Value.ToString());
}
