Getting a response from the user?

Question

C++ / C#

Googled and found only code for python, or using a database

if (msg.Text == "Вход")
            {
                await client.SendTextMessageAsync(e.Message.Chat.Id, "Введите логин");
                if (msg.Text != "Вход")
                {
                    string strmsg = msg.ReplyToMessage.Text;
                    Console.WriteLine("123");
                    await client.SendTextMessageAsync(1111111, strmsg);
                }
            }

Here is my code, but it doesn't work (because the first condition is not true if (msg.Text == "Вход")
