c# initialize a static list in a class

Question

What I'm trying to have is a 2D global list initialized with strings. If I only wanted a simple list I could just initialize the list with strings separated by a comma like this

public static readonly List<string> _architecturesName = new List<string>()
 {"x86","x64" }; 

I have setup a static class "Globals", in this class I'm adding a List based on another class "ArchitecturesClass" to be used as fields for the list similar to what was done here: Are 2 dimensional Lists possible in c#?

 public class ArchecturesClass
 {  public  string Id { get; set; }
    public  string Name { get; set; }         }
    `*test1->*` public static readonly List<ArchecturesClass> ArchitectureList = 
           new List<ArchecturesClass>() { "2", "9"}; 
    `*test2->*` public static readonly List<ArchecturesClass> ArchitectureList = 
           new List<ArchecturesClass>() {architecturesId = "2",
                                         architecturesName = "3"};

The error on the strings is that the collection initialize has some in valid arguments and In the end I want all classes in the project to be able to read something like Globals.ArchtecutreList.ID and a matching Globals.ArchtecutreList.Name; and I would like to initialize this in the global class without being in a method.

Solution

The syntax

new List<ArchecturesClass>() {architecturesId = "2",
                              architecturesName = "3"};

should probably be

new List<ArchecturesClass>() { new ArchecturesClass>() { architecturesId = "2",
                              architecturesName = "3"}};

Collection initializers expect you to provide instances of the type contained in your list.

Your other attempt

public static readonly List<ArchecturesClass> ArchitectureList = 
       new List<ArchecturesClass>() { "2", "9"}; 

fails because "2" and "9" are strings, not instances of ArchitecturesClass.

You cannot initialize the list with values that belong to the object. You have to create a new object and use the shorthand assignments there.

Almost, i think this got it: public static List<ArchecturesClass> archs = new List<ArchecturesClass> { new ArchecturesClass() { architecturesId = "0", architecturesName= "x86"}, new ArchecturesClass() { architecturesId = "9", architecturesName= "x64"} }; Also found this ref which has a good example at bottom msdn.microsoft.com/en-us/library/vstudio/…
