ASP.NET使用single和array反序列化Json对象

Question

我是json的新手，请帮帮我！假设我有以下json对象

{
    "Table": "",
    "Id": "",
    "Column": [
        {
            "ColumnText": "",
            "ColumnSqlName": ""
        },
        {
            "ColumnText": "",
            "ColumnSqlName": ""
        }
    ]
}

我想用asp.net反序列化上面的json，最好的方法是什么？感谢!!!

Answer 1

我建议使用JSON.NET库将对象序列化和反序列化为json

例如：它将json对象反序列化为C＃object ...

string json = @"{
  ""Name"": ""Apple"",
  ""Expiry"": new Date(1230422400000),
  ""Price"": 3.99,
  ""Sizes"": [
    ""Small"",
    ""Medium"",
    ""Large""
  ]
}";

JObject o = JObject.Parse(json);

string name = (string)o["Name"];
// Apple

JArray sizes = (JArray)o["Sizes"];

string smallest = (string)sizes[0];
// Small

MSDN有一个简单的示例供您遵循。如果它是一个服务，可能更容易使用WCF简单地使用它。

您可以使用内置类JavaScriptSerializer。 MyClass是与json结构匹配的类

var serializer = new JavaScriptSerializer();
MyClass instance = serializer.Deserialize<MyClass>(myJson);

Answer 4

    Public Class JsonObj
    Private _Table As String
    Public Property Table() As String
        Get
            Return _Table
        End Get
        Set(ByVal value As String)
            _Table = value
        End Set
    End Property
    Private _Id As String
    Public Property Id() As String
        Get
            Return _Id
        End Get
        Set(ByVal value As String)
            _Id = value
        End Set
    End Property

    Private _Column As JsonSetting()
    Public Property Column() As JsonSetting()
        Get
            Return _Column
        End Get
        Set(ByVal value As JsonSetting())
            _Column = value
        End Set
    End Property
End Class

Public Class JsonSetting
    Private _ColumnText As String
    Public Property ColumnText() As String
        Get
            Return _ColumnText
        End Get
        Set(ByVal value As String)
            _ColumnText = value
        End Set
    End Property

    Private _ColumnSqlName As String
    Public Property ColumnSqlName() As String
        Get
            Return _ColumnSqlName
        End Get
        Set(ByVal value As String)
            _ColumnSqlName = value
        End Set
    End Property
End Class

用法：

Dim o As New JavaScriptSerializer
Dim instance As JsonObj = o.Deserialize(Of JsonObj)(json_str)

感谢您的所有回复，但上述代码可能效果很好。
