获取数组中的最高和最低数字

Question

您好，我有一个服务台应用程序，我有一个填充类别列表的下拉列表，当用户选择该值时，它会自动绑定另一个下拉列表，显示分配给每个类别的管理员代理列表。

现在的问题是，如果将超过 1 个管理员代理分配给特定类别，我希望能够计算每个代理之前打开的票证总数，并获得最低的票数并绑定数量最少的票证下拉文本的门票。因此不需要用户选择管理员代理来分配工作。 这是我的代码。请帮助。

您可以将Min() 和Max() 用于数组和列表。

int[] array = new int[] { 1, 3, 15, 7, 9 };

int min = array.Min();
int max = array.Max();


List<int> list = new List<int>() { 1, 3, 15, 7, 9 };

int min = list.Max();
int max = list.Max();
