如何从数组列表中获取最小值和最大值C＃

Question

所以我知道如何计算平均值，但我不知道如何计算最小值和最大值。我很确定你需要使用for循环，但我不知道如何。

 public Int32 Average
{
    get
    {
        clsSimpleDataConnection Datalayer = new clsSimpleDataConnection();
        List<Int32> saleslist = new List<Int32>();
        saleslist = Datalayer.LoadIntegerList();
        Int32 AnItem;
        Int32 Total = 0;
        Int32 average;
        Int32 itemcount;
        itemcount = saleslist.Count;
        Int32 index = 0;

        while (index < itemcount)
        {
            AnItem = saleslist[index];
            Total = Total + AnItem;
            index++;

        }
            average = Total / itemcount;
        return average;


    }
}

我如何编辑它以便计算最小值和最大值？

Answer 1

var myList = new List<int>();
var min = myList.Min();
var max = myList.Max();

或者如果你想使用循环 所以对于max

int max = int.MinValue;
foreach (var type in myList)
{
    if (type > max)
    {
        max = type;
    }
}

和min

int min = int.MaxValue;
foreach (var type in myList)
{
    if (type < min)
    {
        min= type;
    }
}
