Create c# function to parse JSON weather forcasts

I need help to create function where you input an int array x and a string json. x[] are requests for datapoint at x hours in the future. Eg, 8 and 24 will get the closest prediction (in time) to 8 and 24 hours in the future. (Any hour up to 1000 should be handled) The JSON has many forcast times starting an hour apart and with larger intervals for later times/predictions. GetWeatherForcasts(String json, int[] x) { //find the predictions (object in timeSeries) closest to 8 hours and 24 hours in the future prediction time is: ""timeSeries": [{ "validTime": "2019-02-03T11:00:00Z"," Temperature is the value of the parameter with "name":"t" return (Object with the requested temperatures and some way to identify input to output) } Short if JSON, Full JSON attached. "timeSeries": [{ "validTime": "2019-02-03T11:00:00Z", "parameters": [{ "name": "t", "levelType": "hl", "level": 2, "unit": "Cel", "values": [-17.2] },
