C# GDI+ 图形图像编程
一般的图像特技，如百叶窗，模仿ppt里的特技。都是c++写的。用于LED屏显示的。请问用c#写可以么，有相关经验的人，请推荐一点资料，和书籍。 --------------------编程问答-------------------- 可以，不过绘图效率更要多加考虑 --------------------编程问答-------------------- 我以前学C#时写的几个效果，抛砖引玉[code=C#0]

--------------------编程问答-------------------- 谢谢，还能推荐书籍。不能光看你们的啊。要写特技多了。。 --------------------编程问答-------------------- 书籍问别人吧，我从来没看过书。 --------------------编程问答-------------------- 我通常是想做什么就去做 卡在那里看哪里

百度一下 你就知道
看书没必要吧 实践是编程的唯一真理 --------------------编程问答-------------------- 如果是做页面的，在上面实现这些效果很好的；
如果在Winform里做的话，我基本用的是第三方控件；
我买了本明日科技的C# 范例宝典，里面有，但是觉得效果不是很好；
你需要的话可以把里面的例子源代码给你 --------------------编程问答-------------------- 啊，好啊，我的QQ642730170
麻烦加我啊。 --------------------编程问答-------------------- 等晚上回家了，我白天上班时是用不了QQ的 --------------------编程问答-------------------- 我学过又忘了，赶紧去复习下
补充：.NET技术 , C#
