0	Hi Naveen, We can achieve this in a very easy way. We have a class in C# called Random. Let us Consider a Random class and an ArrayList as follows Random rd = new Random(); ArrayList arr = new ArrayList(); Let us consider nInput is my input integer which will have my maximum number. int nInput = 5; and sOutput is my resultant string which will have all integers in a comma separated format. string sOutput = string.Empty; The code will be. private void DoRandom() { arr.Add(nInput); while(arr.Count <= nInput) { int nTemp = rd.Next(nInput); if(!(arr.Contains(nTemp))) { arr.Add(nTemp); } } foreach(int n in arr) { sOutput += n.ToString()+","; } } So my Output will be like 5,3,1,2,0,4 Nav234, if this helps please login to Mark As Answer. \| Alert Moderator

Hi Naveen,

We can achieve this in a very easy way.

We have a class in C# called Random.

Let us Consider a Random class and an ArrayList as follows

Random rd = new Random();
ArrayList arr = new ArrayList();

Let us consider nInput is my input integer which will have my maximum number.

int nInput = 5;

and sOutput is my resultant string which will have all integers in a comma separated format.

string sOutput  = string.Empty;

The code will be.

private void DoRandom()

 {

           arr.Add(nInput);



            while(arr.Count <= nInput)

                 {

                         int nTemp = rd.Next(nInput);

                         if(!(arr.Contains(nTemp)))

                            {

                               arr.Add(nTemp);

                            }

                 } 

             foreach(int n in arr)

                   {

                       sOutput += n.ToString()+","; 

                  }

}

So my Output will be like 5,3,1,2,0,4
