C # SendKeys.Send

Question

I run the problem using the C # SendKeys.Send method. I am trying to replace keyboard keys with other keys, for example, when I press "a" on the keyboard, I want this key to be "s", for example, when I do this in my code:

if ((Keys)keyCode== Keys.A)
{                    
    SendKeys.Send("s");                    

}

Right now I get only the “sa” character typed in my notebook, but instead of typing “sa”, I need to get only the “s” character in this case, because when I press “a” on my keyboard, there should be replaced by "s".

I tried to remove the last character by adding this line:

SendKeys.Send("{BS}");

But all I have is the symbol "s", and there was the symbol "a".

How can I prevent this?
