我的代码生成的ListBox的项目没有显示任何内容

ListBox listBox = new ListBox();
listBox.DataSource = yourDataSource; // 确保yourDataSource不为空且包含数据

if (yourDataSource != null && yourDataSource.Count > 0)
{
    listBox.DataSource = yourDataSource;
}
else
{
    MessageBox.Show("数据集合为空");
}

/* 确保ListBox没有被设置为display:none或visibility:hidden */

async void LoadDataAsync()
{
    await Task.Delay(1000); // 模拟异步加载数据
    listBox.DataSource = yourDataSource;
}

using System;
using System.Collections.Generic;
using System.Windows.Forms;

public class MainForm : Form
{
    private ListBox listBox;

    public MainForm()
    {
        listBox = new ListBox();
        listBox.Dock = DockStyle.Fill;
        this.Controls.Add(listBox);

        // 模拟数据源
        List<string> data = new List<string> { "Item 1", "Item 2", "Item 3" };
        listBox.DataSource = data;
    }

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new MainForm());
    }
}
