一、代码实例实现功能

将Array转换为List将List转换为Array将Array转换为Dictionary将Dictionary转换为Array将List转换为Dictionary将Dictionary转换为List

二、代码实现

学生类

class Student
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Gender { get; set; }
    }

转换实现代码

static void Main(string[] args)
        {
            #region 创建学生数组
            //创建数组
            Student[] StudentArray = new Student[3];
            //创建创建3个student对象，并赋值给数组的每一个元素
            StudentArray[0] = new Student()
            {
                Id = 0001,
                Name = "Tony",
                Gender = "M"
            };
            StudentArray[1] = new Student()
            {
                Id = 0002,
                Name = "Hulk",
                Gender = "M"
            };
            StudentArray[2] = new Student()
            {
                Id = 0003,
                Name = "Black",
                Gender = "F"
            };

            #endregion
            Console.WriteLine("=================测试打印信息=================");

            //打印Array中学生信息
            Console.WriteLine("打印Array中学生信息:");
            foreach (Student student in StudentArray)
            {
                Console.WriteLine("Id = " + student.Id + " " + " Name = " + student.Name + "  " + " Gender = " + student.Gender);
            }

            //Array转为LIST
            List StudentList = StudentArray.ToList();
            //打印List中的学生信息
            Console.WriteLine("打印List中学生信息:");
            foreach (Student student in StudentList)
            {
                Console.WriteLine("Id = " + student.Id + " " + " Name = " + student.Name + " " + " Gender = " + student.Gender);
            }

            //LIST转为Array
            Student[] ListToArray = StudentList.ToArray();
            Console.WriteLine("打印ListToArray中的学生信息:");
            //打印ListToArray中的学生信息
            foreach (Student student in ListToArray)
            {
                Console.WriteLine("Id = " + student.Id + " " + " Name = " + student.Name + " " + " Gender = " + student.Gender);
            }

            //Array转换为Dictionary
            Dictionary StudentDictionary = StudentArray.ToDictionary(key => key.Id, Studentobj => Studentobj);
            //打印ArrayToDictionary中的学生信息
            Console.WriteLine("打印ArrayToDictionary中的学生信息:");
            foreach (KeyValuePair student in StudentDictionary)
            {
                Console.WriteLine("Id = " + student.Key + " " + " Name = " + student.Value.Name + " " + " Gender = " + student.Value.Gender);
            }

            //Dictionary转换为Array
            Student[] DictionaryToArray = StudentDictionary.Values.ToArray();
            //打印Dictionary转Array中的学生信息
            Console.WriteLine("打印DictionaryToArray中的学生信息:");
            foreach (Student student in DictionaryToArray)
            {
                Console.WriteLine("Id = " + student.Id + " " + " Name = " + student.Name + " " + " Gender = " + student.Gender);
            }

            //List转换为Dictionary
            Dictionary ListToDictionary = StudentList.ToDictionary(key => key.Id, value => value);
            //打印ListToDictionary中的学生信息
            Console.WriteLine("打印ListToDictionary中的学生信息:");
            foreach (KeyValuePair student in ListToDictionary)
            {
                Console.WriteLine("Id = " + student.Key + " " + " Name = " + student.Value.Name + " " + " Gender = " + student.Value.Gender);
            }

            //Dictionary转换为List
            List DictionaryToList = StudentDictionary.Values.ToList();
            //打印DictionaryToList中的学生信息
            Console.WriteLine("打印DictionaryToList中的学生信息:");
            foreach (Student student in DictionaryToList)
            {
                Console.WriteLine("Id = " + student.Id + " " + " Name = " + student.Name + " " + " Gender = " + student.Gender);
            }
            Console.WriteLine("===============END===================");
            Console.ReadLine();
        }
