将一个IEnumerable拆分为多个IEnumerables

public static IEnumerable<IEnumerable<T>> SplitIEnumerable<T>(IEnumerable<T> source, Func<T, bool> predicate)
{
    List<List<T>> result = new List<List<T>>();
    List<T> currentList = null;

    foreach (var item in source)
    {
        if (predicate(item))
        {
            if (currentList == null)
            {
                currentList = new List<T>();
            }
            currentList.Add(item);
        }
        else
        {
            if (currentList != null)
            {
                result.Add(currentList);
                currentList = null;
            }
        }
    }

    if (currentList != null)
    {
        result.Add(currentList);
    }

    return result;
}

List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

var evenNumbers = SplitIEnumerable(numbers, x => x % 2 == 0);
var oddNumbers = SplitIEnumerable(numbers, x => x % 2 != 0);

Console.WriteLine("偶数集合:");
foreach (var sublist in evenNumbers)
{
    foreach (var number in sublist)
    {
        Console.WriteLine(number);
    }
}

Console.WriteLine("奇数集合:");
foreach (var sublist in oddNumbers)
{
    foreach (var number in sublist)
    {
        Console.WriteLine(number);
    }
}
