Parsing Configuration File To Excel-Like View

Question

I have a firewall configuration file that goes like this:

{
    "javaClass": "some text",
    "rules": {
        "javaClass": "java.util.LinkedList",
        "list": [
            {
                "block": true,
                "conditions": {
                    "javaClass": "java.util.LinkedList",
                    "list": [
                        {
                            "conditionType": "DST_PORT",
                            "invert": false,
                            "javaClass": "some text",
                            "value": "21"
                        }
                    ]
                },
                "description": "Block and flag all traffic destined to port 21",
                "enabled": false,
                "flag": true,
                "javaClass": "some text",
                "ruleId": 100018
            },
            {
                "block": true,
                "conditions": {
                    "javaClass": "java.util.LinkedList",
                    "list": [
                        {
                            "conditionType": "SRC_ADDR",
                            "invert": false,
                            "javaClass": "some text",
                            "value": "1.2.3.4/255.255.255.0"
                        }
                    ]
                },
                "description": "Block and flag all TCP traffic from 1.2.3.0 netmask 255.255.255.0",
                "enabled": false,
                "flag": true,
                "javaClass": "some text",
                "ruleId": 100019
            },
            {
                "block": true,
                "conditions": {
                    "javaClass": "java.util.LinkedList",
                    "list": [
                        {
                            "conditionType": "DST_ADDR",
                            "invert": false,
                            "javaClass": "some text",
                            "value": "1.2.3.4/255.255.255.0"
                        },
                        {
                            "conditionType": "DST_PORT",
                            "invert": false,
                            "javaClass": "some text",
                            "value": "1000-5000"
                        }
                    ]
                },
                "description": "Accept and flag all traffic to the range 1.2.3.1 - 1.2.3.10 to ports 1000-5000",
                "enabled": false,
                "flag": true,
                "javaClass": "some text",
                "ruleId": 100020
            }
        ]
    },
    "version": 1
}

I'm trying to extract the list part, then, extract parts of it for storing the data.

Now, I'm able to load the whole file using myConfigDetails.Text = File.ReadAllLines("firewall.settings_9.js");, but I'm unable to extract the data I want .. The rule can have no conditions, single conditions or multiple conditions ...

I created the class below to store the data in temporarily for further usage:

public class fwDATA
{
    public string ruleID;
    public bool ruleBlock;
    public string ruleValue;
    public string ruleDesc;
    public bool ruleEnabled;
    public bool ruleFlag;
}

Can someone guide me to the correct way to extract the list parts (both the rule and conditions)

Parts I need:

• "block"
• "conditionType"
• "value"
• "description"
• "enabled"
• "flag"
• "ruleId"
