1、C#操作Excel的类以及其运用举例说明1、曲育这两天Ih于某种须要，探讨了吓.NET中对EXCel的互操作.之前主要是卜脆通过第三方的组件等方式来操作的Excel,这次细致的探讨了一下，对常用的EXCel操作需求做了一个简洁的总结，比如创建EXceI,设置单元格样式，合并单元格.导入内存中的DataTable,插入图片、图表等，在此茶拙上借助于MicrosoftQfficeJnterop.ExceI对这些操作进行了M装最终形成了ExceIHandlert,本文主要对自己封装的这个类进行简洁的举例说明,关于此类的完整代码参见第三部分.国总：对于命名空间MiCrOSoft.OfficeJnter
