[Solved] How to compare number with all number in List not loop List?

by


Do you mean you want to add i to values if there is no i in that list?
Use FindIndex to check if list contains i it will return the index. If it is not, it will return -1.

List<int> values = new List<int>();
private void CheckCondition()
{
    for (int i = 0; i < 5; i++)
    {
        int idx = values.FindIndex(item => item == i || item > i);
        if(idx == -1)
        {
           values.Add(i);
           break;
        }
    }
}
