c# - 按另一个数组中指定的顺序对数组进行排序

Question

我有一个键值对列表，我想根据另一个数组中指定的顺序对其进行排序。

var requiredOrder = new String[] { "PH", "HH", "PR", "SR", "UN", "UD", "WD", "WE", "OT" };


        var listToBeSorted = new List<KeyValuePair<string, string>>() {
            new KeyValuePair<string, string>("A","PR"),
            new KeyValuePair<string, string>("B","PH"),
            new KeyValuePair<string, string>("C","HH"),
            new KeyValuePair<string, string>("D","WD"),
            new KeyValuePair<string, string>("E","OT"),
            new KeyValuePair<string, string>("F","UN"),
            .....
        };

'listToBeSorted' 是一个真正的集合，我为需要根据 'requiredOrder' 数组按值排序的下拉列表获取。

Answer 1

您可以使用 Array.IndexOf()

按 requiredOrder 数组中项目的索引进行排序

listToBeSorted = listToBeSorted.OrderBy(x => Array.IndexOf(requiredOrder, x.Value)).ToList();
