c# - how to merge / join two different list into 1 -

I am working on an application for the Windows Phone Platform. Run in a question.

I had 2 different lists, 1 is read directly from the XML file, and by some other calculations. And I want to merge these two lists into 1, so I can display it.

List 1:

  public class studentClass1 {public string studentID {get; Set; } Public String Student FirstName {get; Set; } Public string studentListName {get; Set; }}   
 list 2:  
  public class studentClass2 {public string studentID {get; Set; } Public String StudentGradePoint {Received; Set; }}   
 First of all, I had read studentClass1  
  var studentList = through the studentInndex.Descendants ("student") select new drivers Student List 1 = Student List. ToList ();   
 Secondly, I calculate the function and output of the student grade points in the second list:  
  studentClass2 SG = new student class 2 {studentID = thestudentID , StudentGradpoint = thestudentGradePoint.ToString ()}; StudentList2.Add (SG); StudentListAll = StudentList1 + StudentList2   
 Now, I want to include this two list together so that I can call it and output it on the screen  
  studentResultListBox.Itemsource = StudentListAll;   
 How does a suggestion code look? Thank you.

 Assume that you just want to combine the proper information of both the lists (from this completely Your question is not clear) - A third class introduction  studentClass3  holds all the properties you want and using one to join examples to match with a  studentID :  
  on studentList3 = (s2.stude to join s1.studentID in s2 studentList2 in studentList1 The ntID selection is equivalent to the new studentClass3 () {studentFirstName = s1.studentFirstName, studentID = s1.studentID, studentGradePoint = s2.studentGradePoint, studentLastName = S 1. StudentListName}). ToList (); Usually this problem should be solved when you are trying to combine lists later in XML - for students, three different classes may be confusing, besides recommended. Take a look at the naming conventions, they are a bit far away.
