Well need a easy code but I dont know what to do:
I need to generate a random number like this:


What I can put there? 19 numbers

[Visual Freedom]

Just use Random().Next(1000,9999) and use concat to add them into a row of many

PHP Code


<?php 
Const Chartable As String = "0123456789"
Public Shared Function Randomize(len As Integer) As String
 Static rnd As New Random(New Object().GetHashCode Mod DateTime.Now.Millisecond)
 Return New String(Chartable.Select(Function(x) Chartable(rnd.Next(Chartable.Length))).Take(len).ToArray())
End Function

ONE instance and one alone now mr barret :)

Code

const string numbers = "0123456789";
Random r = new Random();
string num = "";
for(int i = 0; i<=19;i++)
{
   num += numbers[r.Next(0, numbers.Length -1)];
}

Now you just add num to the URL or whatever you want.

EDIT:

I just realized this is the VB section and not the C#, so my code is useless to you.

you lil fucker replicated my version :P hahahaha 🤣

Heres how i would do it:

Code

Dim r As New Random()
Const charMap As String = "1234567890"

Function GetRandomNumberString(len As Integer) As String
    Dim sb As New StringBuilder(len)
    For i As Integer = 0 To len
        sb.Append(charMap(r.Next(charMap.Length)))
    Next
Return sb.ToString()
End Function

And heres a short verson for the lols

Code

Function GetRandomNumberString(len As Integer) As String
    Return String.Concat(Enumerable.Repeat(Function() charMap(r.Next(charMap.Length)), len))
End Function

No idea what u coded haha

Sorry if its basically the same 😭😭

Dont sweat it, nothing is ever owned, everything is copied of something. Heck even nature does that. :P

some one "your" level should know NEVER initialize the random class multiple times.

Its static. There is only one instance.

[Barret]

Its static. There is only one instance.

Just ignore it, hes just being silly. Just look beyond and be fine.

[Sn0wX]

Urgh child's time.

Static cant use different seeds.
It's not thread safe.
This is basic GOOD CODING STANDARDS.

but hey when you guys use so many single instances in your apps i would expect you to carry THEM.

oh wait you do not.

You wouldn't be able to use different seeds if it were static - the Random instance keeps track of that state. By default Random uses the current time as seed

What are you talking about? Objects are reference types, the sttaic var just stores the pointer to the random Instance.
