当我的代码只运行大约1/3时,它实际上会正确绘制,剩下的就是不会绘制一些线条。
Pen pen = new Pen(Color.Black);
Graphics graphics = MainFrm.HangmanImage.CreateGraphics();
switch (NoOfGuesses)
{
case 1://Bottom left leg
graphics.DrawLine(pen, 15, 60, 40, 60);
break;
case 2://Bottom right leg
graphics.DrawLine(pen, 40, 60, 55, 60);
break;
case 3://Middle stock
graphics.DrawLine(pen, 34, 20, 34, 60);
break;
case 4: //Top line
graphics.DrawLine(pen, 34, 20, 55, 20);
break;
case 5: //Rope
graphics.DrawLine(pen, 55, 20, 55, 25);
break;
case 6: //Head
graphics.DrawEllipse(pen, (new Rectangle { X=52, Y=25, Height=5, Width=5 }));
break;
case 7: //Body
graphics.DrawLine(pen, 55, 30, 55, 35);
break;
}
pen.Dispose();
graphics.Dispose();

没有足够的信息可以肯定,但是,我首先要确保您的变量'NoOfGuesses'始终是1-7之间的值,值0或8将最终无效。其次,我会添加一个'默认'案例,以防你的'NoOfGuesses'出于任何原因超出该范围,并且还会画一条线。

我通过在表单的paint事件上运行此代码来解决这个问题,似乎只要它重新刷新表单就会忘记它。
