c# - 根据优先级数组对字符串数组进行排序

Question

我有一个优先列表

List<string> priority = new List<string>() {
              "boss",
              "Project owner",
              "client",
              "manager",
              "client1",
              "client2 ",
              "Intern",
          };

我想根据这个优先级对其他数组进行排序

List<string> arr = new List<string>(){ "client1", "boss", "manager" }
priority.Sort(arr);

它应该返回 ["boss", "manager", "client1"]

注意:可能还有其他项目不在优先级中，因此我们可以将它们放在最后。

Answer 1

在优先级列表中，client 1项目显然有一个额外的空间。但是，您可以根据优先级列表中的索引对数组进行排序:

        List<string> priority = new List<string>() {
          "boss",
          "Project owner",
          "client",
          "manager",
          "client1",
          "client2 ",
          "Intern",
      };

     List<string> arr = new List<string>() { "client1", "boss", "manager" };

     var result= arr.OrderBy(x => Array.IndexOf(priority.ToArray(), x)).ToList();
