   前段时间朋友有个项目要实现将word转换成pdf的功能，当时实现的思路是引用第三方的dll来实现，最近到了新公司看见项目中也有个office转换成pdf的功能，所以就看了一下，发现是直接使用了office自带的功能，只要在项目直接引用进来，调用一下方法就可以了。代码如下：

using Microsoft.Office.Interop.Word;
千万别忘了添加引用

        /// <param name="signatureFile">右下角加的log路径</param>

     刚刚测了一下，这个方法应该是在装过了office2007的电脑上才能使用，msdn中也有这个方法介绍，不过注明是在 (2007 system) 里面的。
