Randomise array elements

[Chiefy]

Hey,
Im doing a project in C# and I need to be able to take an array (say StudentNames[10]), randomise the contents, and then place them in the random order into a new array (randomStudentN ames[10]).
Thankyou.

Nice idea ....

Can you post what you have tried so far .

There are a few ways to write out this method (to randomize an arraylist). Here is the fastest way to never get the same results and will always be randomized because it's based off of "TIME"...

protected void Page_Load(object sender, EventArgs e)
{
ArrayList myArrayList = new ArrayList();
myArrayList.Add("First");
myArrayList.Add("Second");
myArrayList.Add("Third");
myArrayList.Add("Fourth");
myArrayList.Add("Fifth");
myArrayList = RandomizeArrayList(myArrayList);
foreach (string s in myArrayList)
{
Response.Write(s + "<br />");
}
}
 
ArrayList RandomizeArrayList(ArrayList myArrayList)
{
Random myRandom = new Random(DateTime.Now.Millisecond);
ArrayList newArrayList = new ArrayList();
int i;
while (myArrayList.Count > 0)
{
i = myRandom.Next(myArrayList.Count);
newArrayList.Add(myArrayList[i]);
myArrayList.RemoveAt(i);
}
return newArrayList;
}
 

This is just a small example of how you are able to randomize an arraylist, this information can also be databound and displayed on the page in any server control.

Hope this helps,
