Visual Basic - Getting value from an array with an integer

Question

I currently Have an array ...

Dim mTeam(10) As String

In the Form load For visual basic i have

   'Load Teams
    mTeam(1) = "Oklahoma"
    mTeam(2) = "USC"
    mTeam(3) = "LSU"
    mTeam(4) = "Michigan"
    mTeam(5) = "Georgia"
    mTeam(6) = "Texas"
    mTeam(7) = "Tennessee"
    mTeam(8) = "Ohio State"
    mTeam(9) = "Florida State"
    mTeam(10) = "Miami(FL)"

Now what im trying to do, is have the user enter a value between 1-10 in a textbox, and in return. A messagebox will appear with the team name.

Example:

User enters 5 into TextBoxNumber, a message box will apear when i hit button ButtonName, and in that message box it will have the word "Georgia".

TextBoxNumber (Name of input value) ButtonName (button to do all the work and show messagebox)

Any help would be nice, i already have a try catch to have it only take integer values between 1 and 10.

PLEASE NOTE THIS IS FOR VISUAL BASIC , AND IM USING MICROSOFT VISUAL STUDIO 2010

@Satya The index for an array should be an integer, not a string. That code will not work if Option Strict is On — Chris Dunaway

@UniversityStudent: Be aware that you are creating an array with 11 entries like this, the first (index 0) being Nothing. — Christoph

You can attempt to convert the user's value to an integer, and if successful return the array value at that index:

Dim ind As Integer = -1
If Integer.TryParse(TextBoxNumber.Text, ind) Then
    If ind >= 0 AndAlso ind < mTeam.Length
        MessageBox.Show(mTeam(ind).ToString())
    End If
End If
