推荐答案

假设您没有在运行时在 Firstform 中创建 tabcontrol.

Assumed that you have not created a tabcontrol at runtime in the Firstform.

在 FirstForm.cs 中

In FirstForm.cs

    private void button1_Click(object sender, EventArgs e)
    {
        SecondForm obj = new SecondForm(this);
        obj.Show();
    }

    public void addTabpage()
    {
        TabPage tbpg = new TabPage();
        tbpg.Text = "New tabpage";
        tabControl1.TabPages.Add(tbpg);

        this.BringToFront();
    }

在SecondForm.cs中，修改构造函数如下

In SecondForm.cs, change the constructor as follows

    static FirstForm objpub;
    public SecondForm(FirstForm obj)
    {
        InitializeComponent();
        objpub = obj;
    }
    private void button1_Click(object sender, EventArgs e)
    {
        if (objpub != null)
        {
            objpub.addTabpage();
        }

    }
