1.窗体界面设计
//屏幕高度
int ScreenH = 1080;
this.Location = new Point(this.Location.X, ScreenH - this.Height - 20);
//关闭本窗体，打开主窗体
this.Hide();
FrmQQMain frmQQMain = new FrmQQMain();
frmQQMain.ShowDialog();
2.鼠标事件
//鼠标进入时，变成红色
label1.ForeColor = Color.Red;
//鼠标离开时，背景变透明
pictureBox1.BackColor = Color.Transparent;
//颜色浅灰半透明
picShrink.BackColor = Color.FromArgb(50,200,200,200);
//鼠标进入时，切换另一张图片
picLogin.BackgroundImage = Properties.Resources.iconqq;
//鼠标拖动窗体方法
bool isDrag;

//随机出现按钮方法
Random r = new Random();

,r .Next ()%(this.ClientSize .Height -button2 .Height ));
4.C#图片操作
//打开资源管理器(click事件中)
OpenFileDialog ofd=new openfiledialog();//初始化打开文件夹类
ofd.ShowDialog();//显示资源管理器
//显示图片
（click事件外）image imgOriginal;//定义一张图片
(click事件里) string strFileName = ofd.FileName;//获取该位置的文件名
imgOriginal = Image.FromFile(strFileName);//获取选取的图片
pictureBox1.BackgroundImage = imgOriginal;//显示图片
//图片底片化（click事件里）
bitmap bmp=new bitmap（imgoriginal）；//从现有的图像初始化位图类
for(int i=0;i<bmp.width;i++)
{
for(int j=0;j<bmp.height;j++)
{
color c=bmp.getpixel(i,j);//获得原来像素点颜色
color cafter=color.fromargb(255-c.r,255-c.g,255-c.b);//改变
bmp.setpixel(i,j,cafter); //设置回去
}
}
picturebox2.backgroundimage=bmp;
//保存修改后的图片（click事件中）
savefiledialog sfd=new savefiledialog();//初始化保存类
sfd.showdialog();//重载显示资源管理器界面
picturebox2.backgroundimage.save(sfd.filename+".jpg");//获取控件中的背景图片AAA
