Adding the last x list entries

[BigRo]

Hi. I wanna add the last X entries of my list together with X being a changeable property.

the way i do it atm is to just use an if statement for every X i would like, so

if(x==1)
savedListvalue[savedListvalue.Count-1].Value

if(x==2)
savedListvalue[savedListvalue.Count-1].Value + savedListvalue[savedListvalue.Count-2].Value

if(x==3)
savedListvalue[savedListvalue.Count-1].Value + savedListvalue[savedListvalue.Count-2].Value + savedListvalue[savedListvalue.Count-3].Value


and so on and so forth. needless to say that this is rather awkward and static and makes the code really blown up pretty fast

anyone an idea for an more elegant way?

Hello,

Thank you for the question.

It looks like you are just trying to Add the X number of items in the list together is this correct?

Are you trying to on each iteration add only the next value or start with the Count-1 value, then add Count-2 to that, then Count-3 to that etc?

If so you could use a simple loop, depending on what direction of the list you want to iterate you may need to adjust the code:

double accumulatedTotal = 0;
for(int i = savedListvalue.Count - 1; i >  0; i--) 
{
    accumulatedTotal += savedListvalue[i].Value;
}

This would start at the last index of the list and work its way back through the lists count, you could modify this to only do X items if you wanted too.

the += would accumulate the value to the variable so if you are simply trying to add X numbers together, this would be an easy way to condense the code.

I look forward to being of further assistance.
