Asp.Net操作Word内容

如果要正常操作Word　Com组件的话，必须要给用户赋上足够的权限的，

1、运行Dcomcnfg.exe
2、组件服务――计算机――我的电脑――DCOM配置――找到microsoft word 文档

3、点击属性

4、选择“安全性”

5、选定“使用自定义访问权限”和“使用自定义启动权限”

6、分别编辑权限，添加ASPNET,VS Developers,Debugger User //不一定

7、选择“身份标识”，在选定“交互式用户” 即可 （关键步骤）必须

8、在Web.config里加 <identity impersonate="true"/>
