Handling JSON in C#

This is my JSON Input:

{    "assets":[       {          "appid":730,          "contextid":"2",          "assetid":"16106538532",          "classid":"3292478154",          "instanceid":"0",          "amount":"1"       },       {          "appid":730,          "contextid":"2",          "assetid":"16102298435",          "classid":"3291242689",          "instanceid":"0",          "amount":"1"       }, // ...           ],    "descriptions":[       {          "appid":730,          "classid":"3292478154",          "instanceid":"0",          "currency":0,          "background_color":"",          "icon_url":"//url",          "descriptions":[...],          "tradable":0,          "name":"Spectrum Case",          "name_color":"D2D2D2",          "type":"Base Grade Container",          "market_name":"Spectrum Case",          "market_hash_name":"Spectrum Case",          "commodity":1,          "market_tradable_restriction":7,          "marketable":1,          "tags":[//...]       }, // ...            {          "appid":730,          "classid":"3291242689",          "instanceid":"0",          "currency":0,          "background_color":"",          "icon_url":"//url",          "descriptions":[...],          "tradable":0,          "name":"Horizon Case",          "name_color":"D2D2D2",          "type":"Base Grade Container",          "market_name":"Horizon Case",          "market_hash_name":"Horizon Case",          "commodity":1,          "market_tradable_restriction":7,          "marketable":1,          "tags":[//...]       }, // ...    ],    "total_inventory_count":45,    "success":1,    "rwgrsn":-2 }

I only have the AssetID, which is a unique ID for an item

But to get item’s info, first I have to get its ClassID which also stores the item’s info

For Example, I have var assetID = "16106538532"; but I also want the ClassID’s info f.e. "market_hash_name", "icon_url", …

How do I get this in C#? Theoretically, I know how to get the JSON data and how to save it into var json, but I have no clue how to handle the rest. Thank you for helping
