C# Find a set of objects and diplay their information. I must use lambda or Predicate/delegate with FindAll for this

I have to find the names passing through the parameter array in the List with lambda. Should I have to iterate for searching equal names from the array?

 partial class StudentTestScoresProgram      {          static public List<Student> GetStudents()          {              List<Student> students = new List<Student>              {                  new Student { Name = "Michael", Scores = new int[] { 94, 92, 91, 91 } },                  new Student { Name = "Isabelle", Scores = new int[] { 66, 87, 65, 93, 86} },                  new Student { Name = "Chastity", Scores = new int[] { 76, 61, 73, 66, 54} },                  new Student { Name = "Chaim", Scores = new int[] { 94, 55, 82, 62, 52} },                  new Student { Name = "Patience", Scores = new int[] { 91, 79, 58, 63, 55} },                  new Student { Name = "Echo", Scores = new int[] { 74, 85, 73, 75, 86} },                  new Student { Name = "Pamela", Scores = new int[] { 73, 64, 53, 72, 68} },                  new Student { Name = "Anne", Scores = new int[] { 78, 96, 52, 79, 60} }   };                return students;          }      /// <summary>          /// Find a set of students and display their information          ///           /// You MUST use lambda or Predicate/delegate with FindAll for this.          /// </summary>          /// <param name="students">list of students</param>          /// <param name="search">array of student names to find</param>          static void FindStudents(List<Student> students, params string[] search)          {              //I have to fill the code in here.               List<Student> subArray = students.FindAll(i => i.Name == search[]); //This is what I was thinking of          }  

I have to fill the code, how can I search for an array?

The program is

 static void Main(string[] args)          {              List<Student> students = GetStudents();              FindStudents(students, "Bruno", "Tanya", "Tony", "Sami");              FindStudents(students, "Xerxes");          }  

And the output should be like this

Searching for the following students:  Bruno  Tanya  Tony  Sami  Found the following students:  Name: Bruno, Scores: 62, 66, 70, 82  Name: Tanya, Scores: 60, 77, 88, 99  Searching for the following students:  Xerxes  Found the following students:
