使用.Net开发ArcGIS9扩展组件的注册到ArcMAP中

最近碰到一个需求：要求用vs2005平台C#语言开发一个功能，注册到ArcMap中使用，由于最开始自己接触的都是AE接口，对于AO不是很熟悉，对于其扩展也不是很熟悉，所以最近查阅了大量的资料，大概了解了这种需求的解决方案。

       以前对于ArcMAP功能扩展就只知道使用VBA宏进行扩展，而且一般使用VBA也只是使用其来测试不熟悉的几个接口而已。

 

      使用C#开发注册到ArcMAP中COM组件需要注意以下几个关键点：

            一：对于输出的类库需要选择可以注册到COM组件，其中的几个设置，在属性生成中选择“位COM Interop注册”，在AssemblyInfo.cs中修改ComVisiable位true；

           二：对于所输出的类需要添加ArcGIS提供的两个方法，分别为MxCommands.Register(regKey);         

  MxCommands.Unregister(regKey);

          三：将自定义的工具编译好之后，会在当前编译的环境在中自动注册到ArcMAP中，但是对于需要部署到客户机器上的组件来说，这种方法还是有缺陷的；但是好的是.NET提供了注册的方法即RegistrationServices regSrv = new RegistrationServices()下的RegisterAssembly方法和regSrv.UnregisterAssembly(AS)
