.net 简单图表控件 ，介绍测试示例使用部分 [c/s桌面应用程序控件] II
努力写完了b/s的示例部分,现在在把c/s的示例部分也加上,c/s的和b/s的差不多,只有一点儿下差别,不用配置那些xml,不用创建文件夹,因为c/s可以不使用保持图片的方式读取图片,可以直接给控件绑定背景图片更方便,所以c/s不需要再次保存图表生成的图片,可以通过里面的SaveImage(string path)方法把图片保存本地,也可以通过GetImage()方法获取图表图片作为某个控件的背景,其他的一些属性和b/s的属性一致,这里就不在唠叨了.
不知道c/s的程序怎么表达呈现出来,就简单的做了一个类似任务管理器的一个小示例.
这里不用怎么配置,只要将dll复制到bin目录下并引用,然后在工具箱中添加即可.
新建一个应用程序,直接写入以下相应文件代码:
下面的是设计页面(Form1.Designer.cs)文件的部分代码(首先类库的引用要正确):

注意:这些代码是很早的时候写的,当时的注释不是很多,现在只是拿过来用一用引砖抛玉,不过那些代码都是平常使用到的,只有一些,如获取cpu的参数的是我从网上找的,人家就那么写的,里面还有自定义的类,只是为了方便显示图表的数据而创建.
