How to loop through, while adding onto string?

Question

I need to loop through an array and populate a string in the following way

First --> string = array(0) + array(1) + array (2)

Then --> string = array(1) + array (2)

Then --> string = array(2)

How can I accomplish this if the length of the array is dynamic? I am using vb.net Thank you!

Have you got anything so far? You can get the length of an array using .Length — user3510227

if I use for i=0 to array.count string = string + array(i) will work for the first time around but the second time I want without array(0) — Dman

You can use 2 for loops to accomplish this. The first for loop would loop through the whole array and the send loop would be looping through the portion of the array that you want to add to the string.

var tempList = new ArrayList();
tempList.Add("Test1");
tempList.Add("Test2");
tempList.Add("Test3");

var tempString = new System.Text.StringBuilder();
for (int i = 0; i < tempList.Count; i++)
{
    for (int j = i; j < tempList.Count; j++)
    {
        tempString.Append(tempList[j]);
    }
}

i don't see any benefit from taking the OPs arrays and creating an array list?

switched it over to vb for i=0 to templist.count for j=i to templist.count tempstring.append(templist(j)) next Next
