Hi
I need help with trying to join the contents of two arraylists.

I am filling my sorted arrays with file names and want to end up with the following output in a text file.

Leftfile1,Rightfile1
Leftfile2,Rightfile2
Leftfile3,Rightfile3
Leftfile4,Rightfile4
etc

I have no issue with adding to array or saving to a text file. My problem is creating a loop that takes item1 from first array and then item 1 from second array and makes one string out of them separated by a comma and to keep doing this until end of the array.

Can someone please help

Thanks
J

To start with, don't use that obsolete ArrayList. Use System.Collections.Generic.List<>
This is not even a question. What "problem"?
What have you tried so far?

My problem is trying to join each item in array into a single string.
I've been trying to use a for loop with no result

If the count of records in the two array is the same, its easy.

C#

for (int i=0;i<=arrLeft.count;i==)
{
   Console.Writeline(arrLeft[i] + arrRight[i]);
}

If the count is different, then try something like -

C#

int minCount;
if (arrLeft.Length > arrRight)
{
   minCount = arrRight;
}
else
{
   minCount = arrLeft;
}
for (int i=0;i<=minCount;i==)
{
   Console.Writeline(arrLeft[i] + arrRight[i]);
}
