02 button的练习

 private void button1_Click(object sender, EventArgs e)
 {
 MessageBox.Show("我也喜欢你!");
 //if (this.button1.Text == "喜欢")
 //{
 // button2.Visible = false;
 //}

 }
 private void button2_Click(object sender, EventArgs e)
 {
 MessageBox.Show("我还不喜欢你呢！");
 //if (this.button2.Text == "不喜欢")
 //{
 // button1.Visible = false;
 //}

 }

 private void button2_MouseMove(object sender, MouseEventArgs e)
 {
 //Button2移动 不让鼠标点到
 Random suiJi = new Random();
 int x = suiJi.Next(,this.Size.Width-this.button2.Size.Width);
 int y = suiJi.Next(,this.ClientSize.Height-this.button2.Size.Height);

 Point p = new Point(x,y);
 button2.Location = p;

 }

 private void Form1_Load(object sender, EventArgs e)
 {
 MessageBox.Show("做个测试吧！！"); //messagebox是一个类型 类型后面要跟.

 }

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
 {
 //窗体关闭事件的简单写法
 DialogResult re = MessageBox.Show("确定关闭吗", "询问", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
 if (re == DialogResult.No)
 {
 e.Cancel = true;
 }
 }
