.net 簡單圖表控件 (介紹測試示例使用部分) [c/s桌面應用程序控件] II

　　 努力寫完了b/s的示例部分,現在在把c/s的示例部分也加上,c/s的和b/s的差不多,只有一點兒下差別,不用配置那些xml,不用創建文件夾,因為c/s可以不使用保持圖片的方式讀取圖片,可以直接給控件綁定背景圖片更方便,所以c/s不需要再次保存圖表生成的圖片,可以通過里面的SaveImage(string path)方法把圖片保存本地,也可以通過GetImage()方法獲取圖表圖片作為某個控件的背景,其他的一些屬性和b/s的屬性一致,這里就不在嘮叨了.

　　不知道c/s的程序怎么表達呈現出來,就簡單的做了一個類似任務管理器的一個小示例.

　　這里不用怎么配置,只要將dll復制到bin目錄下並引用,然后在工具箱中添加即可.

新建一個應用程序,直接寫入以下相應文件代碼:

　　注意:這些代碼是很早的時候寫的,當時的注釋不是很多,現在只是拿過來用一用引磚拋玉,不過那些代碼都是平常使用到的,只有一些,如獲取cpu的參數的是我從網上找的,人家就那么寫的,里面還有自定義的類,只是為了方便顯示圖表的數據而創建.
