Pass JSON Array to WebServices

You have to create a JSON string of Array Object and pass the Object to Web Service. Most Advantages of this type of calling functionality is not need to Type Conversation or Casting.

Step 1: Create Simple html page like.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>

<title>Untitled Page</title>

</head>

<body>

BindContactInfo();

function BindContactInfo() {

//Create an array of Contact Details class.

var contact = new Array();

for (var i = 0; i < 2; i++) {

var ContactInfo = new Object();

if (i == 0) {

ContactInfo["FirstName"] = "Jayendrasinh";

ContactInfo["LastName"] = "Gohil";

ContactInfo["Address"] = "A/74 Ankur";

ContactInfo["City"] = "Ahmedabad";

ContactInfo["State"] = "Guj";

ContactInfo["Zip"] = 382350;

}

else if (i == 1) {

ContactInfo["FirstName"] = "Pratipalsinh";

ContactInfo["LastName"] = "Gohil";

ContactInfo["Address"] = "A/74 Anour";

ContactInfo["City"] = "Vadodara";

ContactInfo["State"] = "Guj";

ContactInfo["Zip"] = 382350;

}

contact[i] = ContactInfo;

}

/* Create a data transfer object (DTO) with the

remember DTO Parameter and Web Sevice Parameter name are same.

var DTO = { 'ContactInfo': contact };

$.ajax({

contentType: "application/json; charset=utf-8",

data: JSON.stringify(DTO),

dataType: "json",

type: "POST",

url: "ContactService.asmx/AddContactInfo" //Call the Web Service Method.

});

}

</script>

</body>

</html>

Step 2: Create class name ContactInfo

public class ContactInfo

{

public string FirstName { get; set; }

public string LastName { get; set; }

public string Address { get; set; }

public string City { get; set; }

public string State { get; set; }

public string Zip { get; set; }

public void Add()

{

// Save me here!

}

Step 3: Create Web Service Name ContactService like

using System;

using System.Collections;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Xml.Linq;

namespace OraclewithODPTest

{

/// <summary>

/// Summary description for ContactService

/// </summary>

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[ToolboxItem(false)]

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

[System.Web.Script.Services.ScriptService]

public class ContactService : System.Web.Services.WebService

{

[WebMethod]

public void AddContactInfo(List<ContactInfo> ContactInfo)

{

if (ContactInfo != null)

{

foreach (var item in ContactInfo)

{

}
