VB.NET的代码转为C#
Dim WithEvents RecoContext As SpeechLib.SpSharedRecoContext
Dim Grammar As SpeechLib.ISpeechRecoGrammar

Dim m_bRecoRunning As Boolean
Dim m_cChars As Short


Private Sub SimpleDict_Load(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles MyBase.Load
SetState(False)
m_cChars = 0
End Sub

Private Sub btnStart_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles btnStart.Click
System.Diagnostics.Debug.Assert(Not m_bRecoRunning, "")
If (RecoContext Is Nothing) Then
RecoContext = New SpeechLib.SpSharedRecoContext
Grammar = RecoContext.CreateGrammar(1)
Grammar.DictationLoad()
End If

Grammar.DictationSetState(SpeechLib.SpeechRuleState.SGDSActive)
SetState(True)
End Sub

Private Sub btnStop_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles btnStop.Click
System.Diagnostics.Debug.Assert(m_bRecoRunning, "")
Grammar.DictationSetState(SpeechLib.SpeechRuleState.SGDSInactive)
SetState(False)
End Sub


Private Sub RecoContext_Recognition(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechLib.SpeechRecognitionType, ByVal Result As SpeechLib.ISpeechRecoResult) Handles RecoContext.Recognition
Dim strText As String
strText = Result.PhraseInfo.GetText
txtSpeech.SelectionStart = m_cChars
txtSpeech.SelectedText = strText & " "
m_cChars = m_cChars + 1 + Len(strText)
End Sub
Private Sub SetState(ByVal bNewState As Boolean)
m_bRecoRunning = bNewState
btnStart.Enabled = Not m_bRecoRunning
btnStop.Enabled = m_bRecoRunning
End Sub


这段代码如何转为C#呢?
