C# 我可以将字典中对象的属性显示为 ListControl.DisplayMember 吗？

Question

目的是将列表视为“名称”列表。

这是字典:

class Scripts
    {
        public Dictionary<int, Script> scripts = new Dictionary<int, Script>();
        ...
    }

这是我要查找的属性“名称”:

class Script
    {
        public string name { get; set; }
        ...
    }

问题是:

public partial class MainForm : Form
{
    Scripts allScripts;

    public MainForm()
    {
        InitializeComponent();
        allScripts = new Scripts();
        setupDataSources();
    }

    private void setupDataSources()
    {
        BindingSource ketchup = new BindingSource(allScripts.scripts, null);
        //THIS LINE:
        listBoxScripts.DisplayMember = allScripts.scripts["Key"].name.ToString();
        listBoxScripts.ValueMember = "Key";
        listBoxScripts.DataSource = ketchup;
    }
    ...
}

我只是想不出如何让那条线工作!非常感谢您的建议!

谢谢

您可以绑定(bind)到 Value 并覆盖 Script 类中的 ToString 方法。

private void setupDataSources()
{            
    BindingSource ketchup = new BindingSource(allScripts.scripts, null);
    listBoxScripts.DisplayMember = "Value";
    listBoxScripts.ValueMember = "Key";
    listBoxScripts.DataSource = ketchup;            
}

脚本类:

class Script
{
    public string name { get; set; }

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