I need to have a method that validate the input to make sure it is only character I also allow white space like, "Alton Drive" the code I have is only allow character no white space.

```
 public bool IsCorrectString(string val)
    {
     foreach (char c in val)
      {
       if (!char.IsLetter(c))
        return false;
      }
      return true;
    }

```

I am not sure if regex is better to use here or not?
