Add (Insert) item to Newtonsoft JObject using C# and VB.Net in ASP.Net

Hi dgunners,

You need to use FromObject method of JArray class.

Please refer below sample.

HTML

<asp:Label ID="lblMessage" runat="server" />

Namespace

C#

using Newtonsoft.Json.Linq;

VB.Net

Imports Newtonsoft.Json.Linq

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        JObject jbody = new JObject();
        JObject lineItems = new JObject();
        lineItems.Add("beneficiaryName", JArray.FromObject(new[] { "Receiver 1", "Receiver2" }));
        lineItems.Add("beneficiaryAccount", JArray.FromObject(new[] { "0111222333", "0444555666" }));
        lineItems.Add("bankCode", JArray.FromObject(new[] { "011", "04" }));
        lineItems.Add("beneficiaryAmount", JArray.FromObject(new[] { "10", "50" }));
        lineItems.Add("deductFeeFrom", JArray.FromObject(new[] { "1", "0" }));
        jbody.Add("lineItems", lineItems);
        lblMessage.Text = Newtonsoft.Json.JsonConvert.SerializeObject(jbody);
    }
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim jbody As JObject = New JObject()
        Dim lineItems As JObject = New JObject()
        lineItems.Add("beneficiaryName", JArray.FromObject({"Receiver 1", "Receiver2"}))
        lineItems.Add("beneficiaryAccount", JArray.FromObject({"0111222333", "0444555666"}))
        lineItems.Add("bankCode", JArray.FromObject({"011", "04"}))
        lineItems.Add("beneficiaryAmount", JArray.FromObject({"10", "50"}))
        lineItems.Add("deductFeeFrom", JArray.FromObject({"1", "0"}))
        jbody.Add("lineItems", lineItems)
        lblMessage.Text = Newtonsoft.Json.JsonConvert.SerializeObject(jbody)
    End If
End Sub
