need to create a random number between 10 and 20

Question

I am trying to generate a random number between 10 and 20 for my program but the numbers being generated are less than 1 and are to 2 decimal places e.g. 0.64, 0.34 etc..

Dim TrigB As Random
    Dim numberb As Integer
    TrigB = New Random
    numberb = TrigB.Next(10, 20)
    TrigRdmb.Text = numberb.ToString

what do i need to change so that it produces a number between 10 and 20

thanks

`TrigB.Next(10, 21)` for a range of 10-20 inclusive...something else is fiddling with the result if you are getting fractions in the result. Dont create a new random over and over - create one for the app. As [shown here](https://dotnetfiddle.net/z4AWp3#) — Ňɏssa Pøngjǣrdenlarp, Feb 18 '16 at 23:00
`Random.Next()` returns an integer, If you are getting decimals, your code is messed up somewhere else — Ňɏssa Pøngjǣrdenlarp, Feb 18 '16 at 23:07

Except for the TrigB.Next(10, 20) which you should have written as TrigB.Next(10, 21) to make it inclusive of 20, your code is fine. For Random.Next will Return Integer

If you get value less than 1, then it is likely you call Random.NextDouble and not Random.Next.
