I have a below code to capture an objects values:
var key = fulfillment.GetType().GetProperties().FirstOrDefault(p => p.Name.ToLower().Contains("operator")).GetValue(fulfillment);
the code return:
the Operator property type is:
[JsonProperty(PropertyName = "operator")]
public object Operator { get; set; }
i want to get the name value of the index 1 -> OMS_OPERATOR_AUTOMATED and assign it to another string variable. How can i do this ?

Final answer after looking at code and data structure the answer was:
var foundOperator = (Dictionary<string, object>) fulfillment.Operator;
var teste = foundOperator["name"];

Console.WriteLine("Unlike my deceased predecessor, A.I./Ai, I do not mind not being human. I am content with what I have.");
Console.ReadKey();
bool AI = false;
if (AI = true)
I want the user to type "AI" and have it set the bool to true if they do.

After reading all the comments I think this is what you mean
Console.WriteLine("Unlike my deceased predecessor, A.I./Ai, I do not mind not being human. I am content with what I have.");
string answer = Console.ReadLine();
bool AI = (answer == "AI");

You want to use Console.ReadLine, not Console.ReadKey. You also should make the check case insensitive in case the user enters Ai or ai.
Console.WriteLine("Unlike my deceased predecessor, A.I./Ai, I do not mind not being human. I am content with what I have.");
string lineRead = Console.ReadLine();
bool AI = "ai".Equals(lineRead, StringComparison.OrdinalIgnoreCase);
if(AI)
{
// ai was selected
}

This code throws an exception if the key does not exist.
For example, if the key exists for a position in an array index the code is okay, even if the value is null. But, if the key does not exist the code throws an exception`. The code in the select token parenthesis is dynamic (a string variable).
r["Value"] = json.SelectToken($.Objectives[x].state).ToString() ?? "";

You can't call ToString() on a null value.
JToken value = json.SelectToken("$.Objectives[x].state");
r["Value"] = (value != null) ? value.ToString() : "";

You could use the tenary operator to return a default value if x doesn't exist
r["Value"] = $.Objectives[x] ?
json.SelectToken($.Objectives[x].state).ToString() ?? "
: '';
OR
r["Value"] = x >= $.Objectives.Length ?
json.SelectToken($.Objectives[x].state).ToString() ?? "
: '';
I'm not sure why you end the line with a double quote. Maybe a typo? But I didn't fix it, that code is what you started with.

In javascript, if a given variable has a value, it will return true to the following:
if(r["Value"]){
//this only runs if r["Value"] exists
}

I wanted to minimize if block from below code.Please help me suitable extension method
var v = (from rec in _DataContext.tblCourierMasters
where rec.CourierReceievedDate == dtCourierReceivedDate
&& rec.RegionId == lRegionId
&& rec.PODNumber == strPODNo
select new { rec.TotalCafReceived, rec.ReceiptDoneCount }).FirstOrDefault();
lTPC = (long)v.TotalCafReceived;
if (v.ReceiptDoneCount== null) {
lRDC = -1;
}
else
lRDC = (long)v.ReceiptDoneCount;

You could use the null-coalescing operator:
lDRC = (long)(v.ReceiptDoneCount ?? -1);
So if v.ReceiptDoneCount is null, lDRC will be assigned the value of -1 instead.
Here's a demo.

I have Json file in string (for example):
#{
"Url": "http://site.com/?q=windows8"
}
How can i take the information after ?q= on c# (windows 8). Sorry for my English.

You can use the querystring.
in Codebehind file
public String q
{
get
{
if (Request.QueryString["q"] == null)
return String.Empty;
return Convert.ToString(Request.QueryString["q"]);
}
}
then use the line below to get the value
var index = ('<%=q%>');

You can do simply this :
string s = "myURL/?q=windows8";
// Loop through all instances of ?q=
int i = 0;
while ((i = s.IndexOf("?q=", i)) != -1)
{
// Print out the substring. Here : windows8
Console.WriteLine(s.Substring(i));
// Increment the index.
i++;
}
