前面四章是介绍，我们已经可以成功的通过一个winform程序打开一个VSTA的IDE编程窗口进行二次开发，但是对于我们使用来说是远远不够的，对于二次开发来说，最重要的一点是从主程序调用二次开发时编写的方法。
这一篇，我就简单介绍下如何调用VSTAIDE中编写的方法。
这里调用方法，第一步就是加载VSTA IDE中编写的代码编译而成的程序集(dll文件)到Microsoft.VisualStudio.Tools.Applications.AddIn和Contex中，第二步将准备调用的方法名称传给MethodInfo，通过反射调用实际方法，第三步不再需要使用的时候卸载程序集。
下面用代码进行讲解。
首先在VSTASAMPLE工程里添加一个RunManagement.cs,代码如下：
在VSTAHelper.cs的VSTAHelper类中，添加如下代码：这一篇，我就简单介绍下如何调用VSTAIDE中编写的方法。
