添加文本框C#

Question

在Program.cs中,我添加了:

public void displayControls()
{
    TextBox tb = new TextBox();
    tb.Text = "Enter";
    tb.Location = new Point(300, 300);
    tb.Size = new Size(300, 300);
    tb.Visible = true;
    tb.Show();
    tb.BringToFront();
}

然后在:

static void Main(string[] args)
{
     this.displayControls();
}

但这不起作用.我是否需要从Form.cs访问表单实例并添加到该实例？我需要做什么才能使文本框在表单中可见？

谢谢.

您似乎正在瞄准WinForm应用程序.你需要在你的Form.cs身上做到这一点,你可以在以下Form_Load事件中做到这一点:

private void Form1_Load(object sender, EventArgs e)
{
    TextBox tb = new TextBox();
    tb.Text = "Enter";
    tb.Location = new Point(300, 300);
    tb.Size = new Size(300, 300);
    tb.Visible = true;
    this.Controls.Add(tb); //here add it to the current form instance
}
