Get value of JSON object in VB.net
提问by Lars Holdgaard
I have the following code I would use in C#:
我有以下代码将在 C# 中使用：
var tokenJson = JsonConvert.SerializeObject(tokenJsonString);
var jsonResult = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(jsonString);
var firstItem = jsonResult["data"][0];
However, I have a VB.NET client, and I have no idea how to translate it. I have tried different online tools without a result.

Chosen awnser gives you the row { "token":"1edd6006-678a-4e6a-ab65-4fa60efa8632" } Had the same problem and to get exactly the value of the token you can do:
选择的 awnser 为您提供了行 { "token":"1edd6006-678a-4e6a-ab65-4fa60efa8632" } 遇到了同样的问题，要准确获取令牌的值，您可以这样做：
Dim firstItem = jsonResult.Item("data").Item(0).Value(Of String)("token")
Outputs: "1edd6006-678a-4e6a-ab65-4fa60efa8632"
输出：“1edd6006-678a-4e6a-ab65-4fa60efa8632”
Hope it helps
