C#操作Word2010实现

概述

某项目需要自动生成Word文档，查找了许多资料，发现还是C#实现起来比较容易，也比较灵活。

环境：
Office 2010
Visual Studio 2010
Win10

网上找了很多教程，首先需要设置引用。
1.右击“解决方案资源管理器”中的项目目录下的“引用”，选择“添加引用”，打开“添加引用”对话框
2.在“添加引用”对话框中，选择“COM”>“Microsoft Word 15.0 Object Library”，点击“确定”按钮（这个版本号和本机安装的Word版本有关，2010是15.0）
3.相同操作打开“添加引用”对话框中，选择“浏览”项，查找到”Microsoft.Office.Interop.Word.dll”文件，选中它，点击“确定”按钮。

整个类的代码如下：

using System.Linq;

经调试，编译器提示ApplicationClass()无法匹配接口，上网搜到解答，发现应该是Word兼容性问题。解决办法是点击解决方案中“引用”，选择Microsoft.Office.Interop.Word，选项中选择“嵌入式互操作类型”，将属性设定成FALSE，问题解决。
