The code below should be pretty close to what you are looking for. I made the assumption that there is an outer array, and that arrays can appear anywhere in the hierarchy. (If this is not true, you can simplify the WalkNode method code a bit, but it should work either way.)
using System;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
namespace JsonRecursiveDescent
{
class Program
{
static void Main(string[] args)
{
string json =
@"[
{
""X"":
{
""Title"":""foo"",
""xxxx"":""xxxx""
}
},
{
""Y"":
{
""ZZ"":
{
""Title"":""bar"",
""xxxx"":""xxxx""
}
}
}
]";
JToken node = JToken.Parse(json);
WalkNode(node, n =>
{
JToken token = n["Title"];
if (token != null && token.Type == JTokenType.String)
{
string title = token.Value<string>();
Console.WriteLine(title);
}
});
}
static void WalkNode(JToken node, Action<JObject> action)
{
if (node.Type == JTokenType.Object)
{
action((JObject)node);
foreach (JProperty child in node.Children<JProperty>())
{
WalkNode(child.Value, action);
}
}
else if (node.Type == JTokenType.Array)
{
foreach (JToken child in node.Children())
{
WalkNode(child, action);
}
}
}
}
}
