How to delete items from list using foreach

[EMILO9]

if (r == "delete"){
Console.Write("Who do you want to remove from the list?: ");
int x = Convert.ToInt32(Console.ReadLine());
foreach (var person in Person) {
if (x == person.Id) Person.RemoveAt(x);
}
}

- foreach loop iterates through elements but for performing deletion using RemoveAt(), index must be known.

- for loop can be used with RemoveAt() for such purpose. Here's the pseudo code/algo:

 IF CHOICE == 'DELETE' 
   x = What to delete
   for (int i = 0; i < list.Count; i++){
    if( x == list[i]){
       list.RemoveAt[i];
    }
   }

- Index can also be obtained using IndexOf method, but it returns the first index of an item if found in the list.

You can attempt this code, and I hope it helps you.

var list = new List<int>(Enumerable.Range(1, 10));
for (int i = list.Count - 1; i >= 0; i--)
{
    if (list[i] > 5)
        list.RemoveAt(i);
}
list.ForEach(i => Console.WriteLine(i));

thank you.
