Maybe something like this might help?
using System;
using System.Dynamic;
using System.Collections.Generic;
using Newtonsoft.Json.Linq;
public class Program
{
public static void Main()
{
IDictionary<string,object> rptBusDetails = new ExpandoObject();
rptBusDetails["rptBusDetails"] = new List<object>
{
new Dictionary<string, string>() {{"BusinessOwner", "Mark"}, {"ChartReq", ""}},
new Dictionary<string, string>() {{"BusinessOwner", "Tom"}, {"ChartReq", ""}}
};
var parent = new object[] { rptBusDetails };
foreach(var node in parent)
{
var details = JObject.FromObject(node);
foreach(var detail in details["rptBusDetails"])
{
string owner = detail["BusinessOwner"].Value<string>();
Console.WriteLine(owner);
}
}
}
}

thanks for your reply, Itried your way, but it shows cannot convert object to array at "foreach (var thing in (Array)childNode)" What I want is I am getting the object from my ajax post method in client side, I am getting and object array, which has json fields. I want to get the values of the fields. Below is my json string that is being formed as passed as object { rptBusDetails: [ [{ "BusinessOwner": "mark", "ChartReq": "", "ColorReq": "", "EmailList": "", "ReportApplication": "", "ReportAud": "", "ReportDelivery": "", "ReportDesc": "" }], }

Try converting that object to a JObject (instead of an array) using JObject.Parse (newtonsoft.com/json/help/html/…) and then access properties via stackoverflow.com/a/9010085/1162991
Sandy
no luck Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'Newtonsoft.Json.Linq.JObject'.

How about
JObject o = JObject.FromObject(object); newtonsoft.com/json/help/html/CreatingLINQtoJSON.htm?Sandy
worked like charm, thanks a lot but how do I get the key and value from the JObject ?

What have you tried? something as easy as this should work, based on your question.
List<string> businessOwners = new List<string>();
foreach (object[] objArray in rptBusDetails) {
foreach (object obj in objArray){
businessOwners.Add((JToken)obj["BusinessOwner"].ToString());
}
}
since you didn't say what you wanted to do with the BusinessOwner property, I put them in a list.

Hi Andrew, thanks for your reply, I want to get the value of Business Owner that is "Mark" I tried your solution but it says "cannot apply indexing of type object"
Andrew
@Sandy Right you're using a dynamic object when you really should be using JTokens, try casting the obj as a JToken. Why are you using object as a type anyways?

@Sandy Oh sorry I missed one of the levels you had! I didn't realize it was an array of arrays of JTokens. I corrected it now.
Sandy
I tried again var tempobj = (JToken)(obj[0])["BusinessOwner"]; Cannot apply indexing to object. Should I try post the data in any other format than object, I am not sure how to ? I have array of objects in my client side which I am trying to get into my webmethod in code behind
