having trouble with errors in visual studio,

Are you familiar with C# and .NET ?

Sorry, but I am not familiar with .net, the error is quite obvious but I only fix each statement if it is fixed and will need a long command and it switches to another error:"Severity Code Description Project File Line Suppression StateError CS1061 'Form1.SpeechErrorEventArgs' does not contain a definition for 'SpeechErrorCode' and no accessible extension method 'SpeechErrorCode' accepting a first argument of type 'Form1.SpeechErrorEventArgs' could be found (are you missing a using directive or an assembly reference?) EZFormApplication C:\Users\HP\source\repos\ClassLibrary7\EZFormApplication\Form2.cs 1041 Active"
 
I think there will be something to do, sorry you can help me.
Best regards!
M-TP

This is my code:
private async void OnIntentHandler(object sender, string SpeechIntentEventArgs )
{

WriteDebug("--- Intent received by OnIntentHandler() ---");
WriteDebug(e.Payload);
dynamic intenIdentificationResult = JObject.Parse(e.Payload);
var res = intenIdentificationResult["topScoringIntent"];
var intent = Convert.ToString(res["intent"]);

switch (intent)
{
case "TrackFace":
{
ToggleFaceRecognitionEvent?.Invoke(this, null);
break;

}

case "ComputerVision":
{
var currentBitmap = camera.GetCurrentBitmap;
var cvc = new ComputerVisionCommunicator();
var description = await cvc.RecognizeObjectsInImage(currentBitmap);          (1)

ezb.SoundV4.PlayData(ezb.SpeechSynth.SayToStream(description));
break;
}
case "FindScrewdriver":
{
//We are trying to find screwdriver, first in front, then on the right, last on the left
ezb.SoundV4.PlayData(ezb.SpeechSynth.SayToStream("I am on it"));
this.ezb.Servo.SetServoPosition(HeadServoHorizontalPort, mapPortToServoLimits[HeadServoHorizontalPort].CenterPosition);       (2)
this.ezb.Servo.SetServoPosition(HeadServoVerticalPort, mapPortToServoLimits[HeadServoVerticalPort].MinPosition + 55);            (3)
await Task.Delay(1000);
if (RecognizeObject("screwdriver"))
{
//Forward();
//squatGrabPosition.StartAction_Grab();
//Reverse();
////Grab

ezb.SoundV4.PlayData(ezb.SpeechSynth.SayToStream("Screwdriver is in front of me"));
return;
}
