推荐答案

请不要尝试使用解决方案1;在几乎所有情况下，它都行不通;无论如何，它没有给你一个如何让它工作的正确的想法。



请看我过去的答案：

什么样的俏皮方法是Paint？ （DataGridViewImageCell.Paint（...）） [ ^ ]，

在面板上捕获绘图 [ ^ ]，

如何加速我的vb.net应用程序？ [ ^ ]，

用C＃.net鼠标滚轮缩放图像 [ ^ ]，

mdi子窗体之间的绘制线 [ ^ ]。



除此之外，您可以使用Microsoft图表：

http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.chart%28v=vs.110%29.aspx [ ^ ]（对于.NET v.4.0-4.5）。



对于.NET 3.5，您可以下载Microsoft Chart Controls对于Microsoft .NET Framework 3.5：

Please don't try to use Solution 1; in almost all cases, it won't work; anyway, it does not give you a right idea on how to make it working.

Please see my past answers:
What kind of playful method is Paint? (DataGridViewImageCell.Paint(...))[^],
capture the drawing on a panel[^],
How to speed up my vb.net application?[^],
Zoom image in C# .net mouse wheel[^],
Drawing Lines between mdi child forms[^].

Besides, you can use Microsoft Charts:
http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.chart%28v=vs.110%29.aspx[^] (for .NET v.4.0-4.5).

For .NET 3.5, you can download Microsoft Chart Controls for Microsoft .NET Framework 3.5:
http://www.microsoft.com/en-us/download/details.aspx?id=14422[^].

Graphics gdi = this.CreateGraphics();
            gdi.DrawLine(Pens.Red, new Point(0, 0), new Point(100, 100));
