Impossible to say whether TextBox is the "best way", without more  
specifics.

Basically, if you have a Forms application in which you want to display  
some information, and that information can be formatted as text, and doing  
so it the most natural way to present that information to the user, then  
sure...one of the text-based Forms controls would be appropriate.

For straight-forward display, I prefer the Label control.  But if you want  
the user to be able to select the text (for example, so that they can copy  
and paste it elsewhere), a TextBox would be required.  You can make the  
TextBox read-only so that the user can only select the text, without  
changing it.  If you have a need to include formatting in the display,  
then you'll need to use RichTextBox.

Of course, you can always implement your own custom control to display the  
data in whatever way you like.  So if you have needs beyond what these  
controls provide, that's always an option.
