Answer 1

You can pass a string to function from main as given below:

I am passing string "MyName" to DisplayMessage function.The DisplayMessage function will return me another string which I will receive in displayName variable and can print it.

main()
{
  string name="MyName";
   string displayName=DisplayMessage(name);
Console.WriteLine({0},displayName);
}

public void DisplayMessage(string name)
{
 return "Leon";
}
