I have a list that contains a list of integers and another list that contains a class that holds both an integer and a string.
What I'm trying to do is sort my list alphabetically, putting the entries that exist in the first list first. Here is my code and expected output:
using System; using System.Collections.Generic; using System.Linq; public class Program { public static void Main() { var myList = new List<int>(); myList.Add(5); myList.Add(15); var myclasses = new List<MyClass>(); myclasses.Add(new MyClass {MyId = 8, MyString = "Entry1"}); myclasses.Add(new MyClass {MyId = 12, MyString = "Entry2"}); myclasses.Add(new MyClass {MyId = 1, MyString = "Entry3"}); myclasses.Add(new MyClass {MyId = 15, MyString = "Entry4"}); myclasses.Add(new MyClass {MyId = 9, MyString = "Entry5"}); myclasses.Add(new MyClass {MyId = 5, MyString = "Entry6"}); foreach (MyClass c in myclasses.OrderBy(z => myList.Contains(z.MyId)).ThenBy(z => z.MyString )) { Console.WriteLine("{0} ==> {1}", c.MyId, c.MyString); } // I'm expecting this output: // // 15 ==> Entry4 // 5 ==> Entry6 // 8 ==> Entry1 // 12 ==> Entry2 // 1 ==> Entry3 // 9 ==> Entry5 } public class MyClass { public int MyId { get; set; } public string MyString { get; set; } } } As you can see from my expected output, I want Entry6 and Entry4 to appear first since they appear in the first list. Then I just want an alphabetical list. I thought my LINQ statement would be correct, but its not giving me the correct results. Any help would be appreciated.
