Question

我想反序列化这个字符串，它来自一个rest api，但我不知道该怎么做。

我知道我必须使用字符串的结构创建一个类，并且我必须使用反序列化来运行该命令。

任何人都可以帮助我吗？

使用this service从JSON字符串生成类。它将为您节省大量时间（并且令人头痛）。

之后，您可以考虑使用第三方库来反序列化JSON字符串。你有很多选择，但最流行和最好的选择是JSON.NET。

安装完成后，您可以在反序列化JSON后继续访问所需的任何数据。

实施例

Dim data = JsonConvert.DeserializeObject(Of YourDataClass)("<YourJSONString>");
If data.Success Then
    Console.WriteLine(data.Data.Categories(0).Name);
End If

在Visual Basic中反序列化JSON
