怎么实现单击鼠标图片变小双击鼠标图片变大啊~~~~
所以小妹又来求大神相助啦~下面附上我的零零乱乱的代码。。。TAT
private void pictureBox1_MouseMove(object sender,System.Windows.Forms.MouseEventArgs e)
{
this.Text=String.Concat("当前鼠标位置：","(",e.X.ToString(),",",e.Y.ToString(),")");
/* if (e.Button == MouseButtons.Left)
{
pictureBox1.Location = new Point(Cursor.Position.X - (p.X - cp.X), Cursor.Position.Y - (p.Y - cp.Y));
}*/
}
private void pictureBox1_MouseHover(object sender, System.EventArgs e)
{
this.Text = "单击左键放大图片，单击右键缩小图片，用光标移动图片";
}
private void pictureBox1_MouseLeave(object sender, System.EventArgs e)
{
this.Text = "作品信息查询";
}

{
/* p.X = Cursor.Position.X;
p.Y = Cursor.Position.Y;
cp.X = pictureBox1.Location.X;
cp.Y = pictureBox1.Location.Y;*/

}
double scale = 1.0;
