how to pass set value in one method to another

Question

i am trying to pass Set vlue in one method to another method in bot framework using C#

 

i wrote two methods

 

This is my first method

if (item.PromptOption != "NULL")
{
if (item.PromptOption.Split('!').Length >= 1)
{
questionTExt = item.PromptOption.Split('!')[0];
lstConfirmAction1 = new List<string>();
int getLen = item.PromptOption.Split('!')[1].Split('$').Count();
for (int i = 0; i < getLen; i++)
{
lstConfirmAction1.Add(item.PromptOption.Split('!')[1].Split('$')[i]);
}
// lstConfirmAction.Add(item.PromptOption.Split('!')[1].Split('$')[1]);
}
context.UserData.SetValue(questionTExt, questionTExt);
var val= context.UserData.GetValue<string>(questionTExt);
PromptDialog.Choice(context, this.OnFeedback, lstActions, questiontext, null, 3);
}

My second method

private async Task OnFeedback(IDialogContext context, IAwaitable<string> result)
{
string selectedStatus = string.Empty;
selectedStatus = await result;
var item = trbList1.Where(a => a.ID == childID && a.HeaderOption.ToLower() == selectedStatus.ToLower()).FirstOrDefault();
if (!string.IsNullOrEmpty(item.Text))
{
if (item.Text == "break")
{
isTriggered = false;
SaveQnAData(context, "YES", "TRUE");
await context.PostAsync("Thank You");
}
else
{
var qst = context.UserData.GetValue<string>(questionTExt);
botCon.KyraConverastionDetails.BotReply = qst;
await context.PostAsync(item.Text);
}
}
}
