You have a comma(,) after the last property by info , this shouldn't be there. I always use jsonlint to check if there are any errors in my json objects.

{
    "type":"some_type",
    "version":"0.1",
    "data":
    {
        "item_name_1":
        {
            "id":266,
            "key":"aaa",
            "name":"aaa",
            "title":"title_1",
            "info":
            {
                "property_1":9,
                "property_2":4
            }
        },
        "item_name_2":
        {
            "id":266,
            "key":"bbb",
            "name":"bbb",
            "title":"title_2",
            "info":
            {
                "property_1":93,
                "property_2":24
            }
        }
    }
}

If we ignore the comma, which is apparently a typo

The problem is because item_name can be named different (item_name_1, _2...

Yes, that is entirely correct; the names need to match. If you need to map something that doesn't match, you'll need to either provide a custom converter, or (usually simpler) map the data into a dictionary - ie you might have:

public Dictionary<string, Item> data {get;set;}

(to represent the "data": node)

This will result in key-value pairs, where each key is the field name ( "item_name_1" , etc), and each value is the Item instance (with properties id , key , name , etc).

ie

public class MyRootObject {
    public string type {get;set;}
    public string version {get;set;}
    public Dictionary<string, Item> data {get;set;}
}
pulic class Item {
    public int id {get;set;}
    public string key {get;set;}
    public string name {get;set;}
    public string title {get;set;}
    public Dictionary<string,int> info {get;set;}
}
