Get Length of array JSON.Net

Question

How can I get the length of a JSON Array I get using json.net in C#? After sending a SOAP call I get a JSON string as answer, I use json.net to parse it.

Example of the json I got:

{"JSONObject": [     {"Id":"ThisIsMyId","Value":"ThisIsMyValue"},     {"Id":"ThisIsMyId2","Value":"ThisIsMyValue2"} ]} 

And I parse it and write it in console:

var test = JObject.Parse (json); Console.WriteLine ("Id: {0} Value: {1}", (string)test["JSONObject"][0]["Id"], (string)test["JSONObject"][0]["Value"]); 

This works like a spell, only I don't know the length of the JSONObject, but I need to do it in a for loop. I only have no idea how I can get the length of test["JSONObject"]

But something like test["JSONObject"].Length would be too easy I guess :(..

Answer 1

You can cast the object to a JArray and then use the Count property, like so:

JArray items = (JArray)test["JSONObject"]; int length = items.Count; 

You can then loop the items as follows:

for (int i = 0; i < items.Count; i++) {     var item = (JObject)items[i];     //do something with item }

According to Onno (OP), you can also use the following:

int length = test["JSONObject"].Count(); 

However, I have not personally confirmed that this will work
