I have the following method:
using System.Web.Services;
using System.Web.Script.Services;
using System.Web.Script.Serialization;
using Newtonsoft.Json;
using System.Collections;
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
//[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
// [System.Web.Script.Services.ScriptService]
public class Tripadvisor : System.Web.Services.WebService {
public Tripadvisor () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string HotelAvailability(string api)
{
JavaScriptSerializer js = new JavaScriptSerializer();
string json = js.Serialize(api);
//JsonConvert.SerializeObject(api);
return json ;
}
Here i set ResponseFormat attribute is json s still being returned as XML.
I want to json format using this asmx service Any ideas?
I faced the same issue, and included the below code to get it work.
[WebMethod]
[ScriptMethod(UseHttpGet=true ,ResponseFormat = ResponseFormat.Json)]
public void HelloWorld()
{
Context.Response.Clear();
Context.Response.ContentType = "application/json";
Context.Response.Write("Hello World");
//return "Hello World";
}
Update:
To get a pure json format, you can use javascript serializer like below.
public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(UseHttpGet=true ,ResponseFormat = ResponseFormat.Json)]
public void HelloWorld()
{
JavaScriptSerializer js = new JavaScriptSerializer();
Context.Response.Clear();
Context.Response.ContentType = "application/json";
HelloWorldData data = new HelloWorldData();
data.Message = "HelloWorld";
Context.Response.Write(js.Serialize(data));
}
}
public class HelloWorldData
{
public String Message;
}
However this works for complex types, but string does not show any difference.
