Unity3D C# Random Int Generator

Question

I have used C++ for a long time. Now, I just started working with C# in Unity3D. I'm almost complete at finishing an app but I can't seem to find a working int generator in Unity C# (With Min and Max values). I've tried the following:

r = Random.Range(min, max)

and

Random rand = new Random();
r = rand.next(min, max)

Both didn't work. I know in C++ you use:

r = rand() % max + min;

If you want a random number. But what is the case with Unity C#? Code:

EDIT:

using UnityEngine;
using System.Collections;

public class STarget : MonoBehaviour {
public GameObject inter;
int rand;
public GameObject TS1;
public GameObject TS2;
public GameObject TS3;
public GameObject TS4;
public GameObject TS5;
void Update () {
    rand = Random.Range(1, 6);
}
public void GameRun () {
    switch (rand){
        case 1:
            inter = TS1;
            break;
        case 2:
            inter = TS2;
            break;
        case 3:
            inter = TS3;
            break;
        case 4:
            inter = TS4;
            break;
        case 5:
            inter = TS5;
            break;
    }
    Game.TargetSingle(inter);
    }
}

Coming from C++, just like r = rand() % max + min would give you random numbers between min and max in C++,it is different in C#. First, you use Random.Range(min, max) to get random number in Unity.

Something to really understand is that Random.Range(min, max) will not really give you random from between min and max like it does in C++. It will give you a random number between min an (max-1) if the provided min and the max are integer.

So when you need random number from 1 to 5, add 1 to the max(5) or you will get only numbers from 1 to 4. Random.Range(2, 5+1) or Random.Range(min, max+1). That's probably your problem.
