首先在窗体类里面声明两个变量，来监视鼠标的动作

//鼠标按下标识

bool mouseDown = false;

Point mouseOffset;

在Load事件里加载所有的图片

 

if (File.Exists(GlobalInfo.AppPath + "\\Picture\\login.png"))

this.BackgroundImage = new Bitmap(GlobalInfo.AppPath + "\\Picture\\login.png");

if (File.Exists(GlobalInfo.AppPath + "\\Picture\\button.png"))

{

this.simpleButton1.ImageLocation = ImageLocation.MiddleCenter;

this.simpleButton1.Image = new Bitmap(GlobalInfo.AppPath + "\\Picture\\button.png");

this.simpleButton2.ImageLocation = ImageLocation.MiddleCenter;

this.simpleButton2.Image = new Bitmap(GlobalInfo.AppPath + \\Picture\\button.png);

}

绘制按钮的时候添加上文字

 

//绘制登录按钮

private void simpleButton1_Paint(object sender, PaintEventArgs e)

{

e.Graphics.DrawString("登录", new Font("新宋体", 12, FontStyle.Bold), Brushes.White, 30, 8);

}

窗体的鼠标事件

//鼠标按下

private void FrmLogin_MouseDown(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Left)

{

mouseDown = true;

mouseOffset = new Point(-e.X, -e.Y);

}

}

//鼠标松开

private void FrmLogin_MouseUp(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Left)

{

mouseDown = false;

}

}

//鼠标按下移动

private void FrmLogin_MouseMove(object sender, MouseEventArgs e)

{

if (mouseDown)

{

Point mousePos = Control.MousePosition;

mousePos.Offset(mouseOffset.X, mouseOffset.Y);

this.Location = mousePos;

}

}
