我正在尝试以JSON格式提取OpenLib的内容，并使用相应的数据填充Winform文本框
通过传递本书的ISBN，我已经能够使用webclient从OL下载数据。现在我已经下载了整个JSON数据
Dim urlstring As String = "https://openlibrary.org/api/books?bibkeys=ISBN:" & Trim(txtisbn.Text) & "&format=json&jscmd=data"
Dim sourceString As String = New System.Net.WebClient().DownloadString(urlstring)
Dim urlstring As String = "https://openlibrary.org/api/books?bibkeys=ISBN:" & Trim(txtisbn.Text) & "&format=json&jscmd=data"
Dim sourceString As String = New System.Net.WebClient().DownloadString(urlstring)
txtdesc.Text = sourceString
我能够在复杂的JSON响应中得到结果：

现在我不知道该怎么做才能获取这些数据 我在VS 2019上使用Winform / VB
