I have a textbox which a user will enter states into, CA, NV etc. I want to replace the space between states and add a common between them so I can do a where IN clause.

vb.net Code:
  1. s = States.Text.Replace(" ", ", ")

  2.  
  3. SELECT * FROM Users WHERE State IN (@States)

  4. command.Parameters.AddWithValue("@States", s)

I do it in SQL management studio and it works, in vb.net it gives no errors and no results where I should.

What's is wrong?
