我的代码就是这个..（我刚从这个网站的答案中得到了这个，但它只读取了“hpq_mem”之后的数据，我想要做的是读取所有数据并将其放到一个表中，标头是我的JSON数据中的变量..

尝试以下代码。这假设您只需要来自hpq_mem属性的数据。
Imports System.Text
Imports Newtonsoft.Json
Imports Newtonsoft.Json.Linq
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim myJsonObject = JsonConvert.DeserializeObject(Of Object)(TextBox1.Text)
Dim sb As New StringBuilder()
sb.Append("<table>" & vbLf & "<thead>" & vbLf & "<tr>" & vbLf)
Dim firstIterate = True
For Each hpqMemObject As JObject In myJsonObject("hpq_mem")
If firstIterate Then
For Each keyPair As KeyValuePair(Of String, JToken) In hpqMemObject
sb.AppendFormat("<th>{0}</th>" & vbLf, keyPair.Key)
Next
sb.Append("</tr>" & vbLf & "</thead>" & vbLf & "<tbody>" & vbLf)
firstIterate = False
End If
sb.Append("<tr>" & vbLf)
For Each keyPair As KeyValuePair(Of String, JToken) In hpqMemObject
sb.AppendFormat("<td>{0}</td>" & vbLf, keyPair.Value)
Next
Next
sb.Append("</tr>" & vbLf & "</tbody>" & vbLf & "</table>")
WebBrowser1.DocumentText = sb.ToString()
End Sub
