如何比较枚举元素列表与枚举列表c#

Question

嗨，我有个ENUM

Elementary_Education = 1,
High_School_Incomplete = 2,
High_School_Complete = 3,
Secondary_Technical_Or_Vocational = 5,
Vocational_Education_Student = 7,
Higher_Education_Institution__Student = 9

然后我有一个人，例如，他有一些这样的教育，例如，他有三个人: High_School_Incomplete High_School_Complete Secondary_Technical_Or_Vocational

我希望从这个例子中获得最高值: Secondary_Technical_Or_Vocational。

例如，result.degree是Enum元素，它必须得到我想要的enum值。applicant.Educations是教育的列表。每个元素都有1度元素。对每种原料进行比较，得到最高的枚举元素度。

result.Degree = applicant.Educations.Where(x => (int)x.Degree)

Answer 1

您可以使用Max获得最大程度。要将其赋值给result，需要将其转换回枚举类型：

result.Degree = (NameOfYourEnum)list.Max(x => x.Degree);

Answer 2

最简单的方法是对学位进行排序，然后取第一个。

result.Degree = applicant.Educations.OrderByDescending(x => x.Degree).FirstOrDefault();

编辑：忘记了Max.That更好。

Answer 3

问题不太清楚，所以我作了一些假设。它看起来像你所说的一个人，有一个教育的列表，这些教育应该是一个学位的列表，每个都有一个枚举值。

您希望从该列表中获得最高值，并将其转换为枚举值。

因此，通过这样的代码设置：

 public class Person
{
    public List<Education> Educations = new List<Education>();
}

public class Education
{
    public Enums.DegreeType Degree { get; set; }
}

public class Enums
        {
            public enum DegreeType
            {
                Elementary_Education = 1,
                High_School_Incomplete = 2,
                High_School_Complete = 3,
                Secondary_Technical_Or_Vocational = 5,
                Vocational_Education_Student = 7,
                Higher_Education_Institution__Student = 9
            }
        }

我们现在可以这样做：

 var person = new Person();
            person.Educations.Add(new Education { Degree = Enums.DegreeType.High_School_Complete });
            person.Educations.Add(new Education { Degree = Enums.DegreeType.Vocational_Education_Student });

            var highestEd = person.Educations.Select(p => (int)p.Degree).Max();
            Enums.DegreeType enumHighest;
            Enum.TryParse(highestEd.ToString(), out enumHighest);

请注意，我是如何从列表中提取最高教育的，然后如果需要的话，我可以将其解析回其枚举值。
