使用另一个类C# WinForms在窗体类中添加/删除控件对象

using System;
using System.Windows.Forms;

public class ControlManager
{
    private Form form;

    public ControlManager(Form form)
    {
        this.form = form;
    }

    public void AddControl(Control control)
    {
        form.Controls.Add(control);
    }

    public void RemoveControl(Control control)
    {
        form.Controls.Remove(control);
    }
}

public partial class MainForm : Form
{
    private ControlManager controlManager;

    public MainForm()
    {
        InitializeComponent();
        controlManager = new ControlManager(this);
    }

    private void addButton_Click(object sender, EventArgs e)
    {
        Button button = new Button();
        button.Text = "New Button";
        controlManager.AddControl(button);
    }

    private void removeButton_Click(object sender, EventArgs e)
    {
        // 假设要删除最后一个添加的按钮
        if (controlManager.Controls.Count > 0)
        {
            Control lastControl = controlManager.Controls[controlManager.Controls.Count - 1];
            controlManager.RemoveControl(lastControl);
        }
    }
}
