Seeking guidance on json as a beginner! Let's consider the below json object:
{
"Table": "",
"Id": "",
"Column": [
{
"ColumnText": "",
"ColumnSqlName": ""
},
{
"ColumnText": "",
"ColumnSqlName": ""
}
]
}
I'm looking for assistance in deserializing this json using asp.net. What would be the most optimal approach? Appreciate any help!
I highly recommend using the JSON.NET library for handling object serialization and deserialization in JSON format.
As an illustration, take a look at how it can deserialize a JSON object into a C# object:
string json = @"{
""Name"": ""Banana"",
""Expiry"": new Date(1230422400000),
""Price"": 2.99,
""Sizes"": [
""Small"",
""Medium"",
""Large""
]
}";
JObject obj = JObject.Parse(json);
string itemName = (string)obj["Name"];
// Banana
JArray itemSizes = (JArray)obj["Sizes"];
string smallestSize = (string)itemSizes[0];
// Small
This approach simplifies the process of working with JSON data in your C# applications.
For those looking for guidance, MSDN offers a straightforward example to utilize. Alternatively, utilizing WCF may be a more streamlined approach when dealing with services.
An efficient way to handle JSON serialization in C# is by utilizing the JavaScriptSerializer class provided by .NET framework. Simply create an instance of this class and use it to deserialize your JSON string into an object of type MyClass:
var serializer = new JavaScriptSerializer();
MyClass myObject = serializer.Deserialize<MyClass>(jsonString);
Introducing the JsonObj Class:
This JsonObj class consists of properties for Table, Id, and Column with their respective getters and setters. The Column property is an array of JsonSetting objects.
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
How to Use:
Create a new instance of JavaScriptSerializer and deserialize the JSON string into an object of type JsonObj.
Dim o As New JavaScriptSerializer
Dim instance As JsonObj = o.Deserialize(Of JsonObj)(json_str)
