Please help me, How to read mintemp from the following json

JavaScript

"mintemp":29,"maxtemp":36,"avgtemp":32,"totalsnow":0,"sunhour":8.7,"uv_index":8}}}"

What I have tried:

VB

Dim request As HttpWebRequest = DirectCast(WebRequest.Create(xUrl), HttpWebRequest)
        Dim response As HttpWebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
        Dim reader As StreamReader = New StreamReader(response.GetResponseStream())
        Dim o As JObject = JObject.Parse(reader.ReadToEnd)
        Dim fc As String = o("forecast")("date")("mintemp")

Your JSON is probably not properly formatted, try this:

Dim o As JObject = JObject.Parse(
    "{'forecast':{'2019-10-14':{'date':'2019-10-14','date_epoch':1570838400, 'mintemp':29,'maxtemp':36,'avgtemp':32,'totalsnow':0,'sunhour':8.7,'uv_index':8}}}")

Dim fc As String = o("forecast")("2019-10-12")("mintemp").ToString()
Console.WriteLine(fc)

If you want to use the current date:

Dim fc As String = o("forecast")(DateTime.Now.ToString("yyyy-MM-dd"))("mintemp").ToString()
