private void button1_Click(object sender, EventArgs e)
{
System.Windows.Forms.TextBox tb = new TextBox();
tb.Location = new Point(100,100);
this.Controls.Add(tb);
}
不知道你要加到哪里去 如果是要加到留言板的那个框框里面就用+=就好了
TextBox tx= new TextBox()
tx.Text = "";
this.Panel.Add(tx);
可以用Label
Label label=new Label();
label.location=new Point(x,y);
label.Text=richTextBox.Text;
this.Controls.Add(label);
