How to remove elements from an array

Question

Hi I\'m working on some legacy code that goes something along the lines of

for(int i = results.Count-1; i >= 0; i--)
{
  if(someCondition)
  {
     result         


        

Answer 1

a couple of options:

List indexesToRemove = new List();
for(int i = results.Count; i >= 0; i--)
{
  if(someCondition)
  {
     //results.Remove(results[i]);
       indexesToRemove.Add(i);
  }
}

foreach(int i in indexesToRemove) {
results.Remove(results[i]);
}

or alternatively, you could make a copy of the existing list, and instead remove from the original list.

//temp is a copy of results
for(int i = temp.Count-1; i >= 0; i--)
{
  if(someCondition)
  {
     results.Remove(results[i]);
  }
}
