Hi,I have List which Contains the elements 99,86,87,100,101,104
From these I want to pop the elements from list from 104 to 87.
i.e remaining List should be 99,86. So how can I dynamically remove elements from 104 to 87

Starting with .NET 2.0, you can use the 'RemoveRange operator:

C#

List<int> intList = new List<int>{99,86,87,100,101,104};

intList.RemoveRange(intList.IndexOf(87),4);

You have 2 options

1. Create a new list with the elements in that you want
2. iterate over the list in reverse for example

C#

    //create list
    List<int> data = new List<int>();
    for (int i = 0; i < 100; i++)
    {
        data.Add(i);
    }

    //remove elements that are greater than 90
    for(int x = 99; x >= 0; x--)
    {
        if(data[x] > 90)
        {
            int c = data[x];
            data.Remove(c);
        }
    }
</int></int>

Solution 1

Try:

C#

List<int> list = new List<int>() { 99, 86, 87, 100, 101, 104 };
int index = list.IndexOf(87);
while (index >= 0 && index < list.Count)
    {
    list.RemoveAt(index);
    }
