在論壇看到這個(gè)帖子,覺得有意思,就實(shí)現(xiàn)了一下。其實(shí)這個(gè)問題以前的高人寫了文章的。好像是net_lover吧，記的不是很清楚。

代碼如下：

using System;
using System.Windows.Forms;
class test
{
Form frm = new Form();
Button btnOK = new Button();
TextBox txtPsw = new TextBox();

static void Main(string [] args)
{
test temp = new test();
temp.showFrm();
//Console.ReadLine();
}

private void showFrm()
{
btnOK.Text = "確定";
frm.Text = "登陸";
txtPsw.Location = new System.Drawing.Point(10,10);
btnOK.Location = new System.Drawing.Point(txtPsw.Left,txtPsw.Top + txtPsw.Height + 10);
btnOK.Click += new System.EventHandler(btnOKClick);
frm.FormBorderStyle = FormBorderStyle.FixedDialog;
frm.Controls.Add(txtPsw);
frm.Controls.Add(btnOK);
frm.StartPosition = FormStartPosition.CenterScreen;
frm.ShowDialog();
}

private void btnOKClick(object sender, System.EventArgs e)
{
//驗(yàn)證信息
MessageBox.Show(txtPsw.Text);
}
}
