本文實例講述了C#采用OpenXml給word里面插入圖片的方法，分享給大家供大家參考。具體分析如下：

首先需要指出的是在MSDN官網有完整的OpenXML教程，雖然是全英文的不過還是很有幫助的。

注，原來摘抄代碼里面沒有模板，在copy過來發現插入word中的圖片大小不一樣，我們如何查找設置圖片大小帶代碼的那一塊，建議自己用在word里面插入一張圖片，通過OpenXml Tools 反編譯出C#代碼，然后改變圖片的大小，再次反編譯。

使用byeond compare 【http://www.scootersoftware.com/ 下載地址】比較C#代碼，就會發現是因為new DW.Extent() { Cx = 990000L, Cy = 792000L} 是因為這段設置造成的。以后其實很多地方都可以借助OpenXml Tools反編譯來進行對比。查看設置樣式的屬性位置。

示例代碼如下：
