在c#中的多个List <User>中拆分List <User>

List<User> list1 = new List<User>();
List<User> list2 = new List<User>();
List<User> list3 = new List<User>();

// 将原始列表拆分成多个列表
List<List<User>> splitLists = new List<List<User>> { list1, list2, list3 };

int startIndex = 0;
int batchSize = (int)Math.Ceiling((double)originalList.Count / splitLists.Count);

foreach (List<User> splitList in splitLists)
{
    int endIndex = Math.Min(startIndex + batchSize, originalList.Count);
    splitList.AddRange(originalList.GetRange(startIndex, endIndex - startIndex));
    startIndex = endIndex;
}

List<User> originalList = new List<User>();
List<User> list1 = new List<User>();
List<User> list2 = new List<User>();
List<User> list3 = new List<User>();

var partitioner = Partitioner.Create(originalList, true);

Parallel.ForEach(partitioner, (user) =>
{
    // 根据需要，可以在此处添加条件以将用户添加到特定列表中
    if (user.SomeProperty == "SomeValue")
    {
        list1.Add(user);
    }
    else if (user.SomeProperty == "AnotherValue")
    {
        list2.Add(user);
    }
    else
    {
        list3.Add(user);
    }
});
