Speech SDK 5.1 语音转换文字有关问题,帮小弟我把上面的vb.net 改成c

Speech SDK 5.1 语音转换文字问题,帮我把下面的vb.net 改成c#
下面的vb.net 看不懂，哪位帮个忙，改成c#的，谢谢！！！



需要下载MS的语音识别SDK开发包

speechsdk51.exe
speechsdk51LangPack.exe
speechsdk51MSM.exe



windows程序版的搞定了，web应用程序来实现怎么也不行 

贴出windows版的结帖了 
Private WithEvents RecoContext As SpeechLib.SpSharedRecoContext
