Question

您好我有一个服务台应用程序，我有一个下拉列表，其中填充了类别列表，在用户选择值时，它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，如果为一个参与者类别分配了多个管理代理，我希望能够在每个代理之前计算打开票证的总数并获得最低值，并绑定具有最小数量的那个下拉文本的票证。所以不需要用户选择管理代理来分配工作。继承我的code.pls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();

获取数组中的最高和最低数字
