1、如何安装OWC组件 OWC是Office Web Compents的缩写，即Microsoft的Office Web组件，包含SpreadSheet组件、Chart组件、PioTable组件和Data Source组件。
只要装了 Office 办公软件 ，在 C:\Program Files\MSECache\owc11_12 中会有一个安装文件： OWC11.msi (offic 2003)
2、安装完成后，新建一个工程，再添加引用...-->com--> Microsoft Office Web components 11.0 在bin文件夹中：Interop.OWC10.dll
引用空间：using Microsoft.Office.Interop.Owc11;
