Where is the data coming from and why do you need two datasets?

What have you tried?

It can be done in a single loop too, but why do you need it and where from such scenario came?

Two DataSets or two sets of data, this does make a difference!

Hey, you can create a generic list of your objects. Loop through both result sets and add them to the list. Let's assume your items are a string :

C#

List<string> myItems = new List<string>();

foreach (string firstListItem in firstCollection)
{
  myItems.Add(firstListItem)
}
foreach (string secondListItem in secondCollection)
{
  myItems.Add(secondListItem);
}
</string></string>

Then loop trough the entire result and calculate whatever you want :

C#

for (int i = 1; i < myItems.Count; i++)
{
  // Do something with myItems[i-1] and myItems[i]
}

Good luck!

if i understand correctly?

Simple way but not optimizd

1)
Create new data table.

3) Add all data from table1 and table2

4) sort new datatable

5)
indx column
[0] A
[1] b
[2] c
[3] d
[4] e
[5] f
[6] g
[7] h

loop for sum
i=0;i<=7; i++

sum[0] = newable[i]+newtable[i+1];
i =i +1;

so sum will populated 4 time.
