Question

I want to convert the below code to LINQ or Lambda expression.

for (int indexprod = 0; indexprod < tempProduct.Count; indexprod++)
{
  for (int index = 0; index < tempProduct[indexprod].Prices.Count; index++)
  {
    if (tempProduct[indexprod].Prices[index].Term == null || tempProduct[indexprod].Prices[index].Term == 0)
    {
      tempProduct[indexprod].Prices.Remove(tempProduct[indexprod].Prices[index]);
      index--;
    }
  }

  if (tempProduct[indexprod].Prices.Count == 0)
  {
    tempProduct.Remove(tempProduct[indexprod]);
    indexprod--;
  }
}

I tried to do this:

List<Product> tempprod1= (from p in products
                     from pr in p.Prices
                     where pr.Term == 0
                     select p).ToList<Product>();

but not able to figure out how to remove the price element when pr.Term!0.

Answer 1

Here you have:

tempProduct
  .ForEach(p => p.Prices.RemoveAll(price => (price.Term ?? 0)==0 ))
  .RemoveAll(p => p.Prices.Count == 0);

Hope this helps. Cheers
