Hi all,
I have a problem with this snippet:

decimal? totalValue = null;

foreach (decimal? value in valuesList)
{
if (!value.HasValue)
continue;

totalValue = totalValue ?? 0;
totalValue += value;
}

I need to Round with zero decimals the totalValue (of Decimal? type).

How can I solve?

Thank in advance.

Use the Decimal.Round method.

I think that the code is cleaner this way:

decimal? totalValue = null;
foreach (decimal? value in valuesList) {
if (value.HasValue) {
totalValue = (totalValue ?? 0) + value.Value;
}
}
if (totalValue.HasValue) {
totalValue = Decimal.Round(totalValue.Value);
}

Instead of (totalValue ?? 0) you can also use
totalValue.GetValueOrDefaul(0).

Perfect, thank you very much Goran.

This is available in C# 3.0?
Unfortunately I must use C# 2.0.

No, it's available in framework 2.0.

(Note my typo; it's GetValueOrDefault, not GetValueOrDefaul.)
