解决 在某个线程上创建的控件不能成为在另一个线程上创建的控件的父级

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
Thread t = new Thread(new ThreadStart(CreateUI));
t.Start();
}

private void CreateUI()
{
AddTextBox();
}

private void AddTextBox()
{
if (this.InvokeRequired)
{
this.Invoke(new MethodInvoker(delegate { AddTextBox(); }));
return;
}
TextBox tb = new TextBox();
tb.Text = "test";
this.Controls.Add(tb);
}

}
