Converting Object Properties to Array

Question

public class myObj
{
    public string ob1 { get; set; }
    public string ob2 { get; set; }
}

List<myObj> objlist = new List<myObj>();

objlist.Add(new myObj
{
    ob1 = "A",
    ob2 = "1"
});
objlist.Add(new myObj
{
    ob1 = "B",
    ob2 = "2"
});

List<string[]> converted = MyConvert(objlist);


public static List<string[]> MyConvert(List<objlist> mobj)
{
    foreach (objlist item in mobj)
    {
        string[] arr = ((IEnumerable)item).Cast<objlist>()
                         .Select(x => x.ToString())
                         .ToArray();
    }
}

I've been trying to convert the object objlist to a List of string array. I've searched the net and found IEnumerable might help, but I got stopped by an error when I run the program..

 

System.InvalidCastException

HResult=0x80004002

Message=Unable to cast object of type 'objlist' to type 'System.Collections.IEnumerable'.
