ASMX Returning a pure string

I have an ASP.NET web service (.asmx). My service is defined like the following:

[System.Web.Services.WebService(Namespace = "http://tempuri.org/")]
[System.Web.Services.WebServiceBinding(ConformsTo = System.Web.Services.WsiProfiles.BasicProfile1_1)]
public class MyService : System.Web.Services.WebService
{
  [System.Web.Services.WebMethod]
  public string GetResult()
  {
    string result = "";

    int day = System.DateTime.UtcNow.Day;
    if ((day % 1) == 1)
      result = "odd";
    else
      result = "even";
    return result;
  }
}

Currently, if I call this service method, I get the following result:

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">even</string>

My issue is, I need to return just the string part. I do NOT want to return the wrapping XML. How do I do this with an .asmx?

Thanks!

Does it need to be an .asmx web service for this? I mean, by excluding the SOAP envelope you're essentially saying "this is not a SOAP web service" as it is, so why not take it a step further and make it a regular .aspx page instead of an .asmx web service.

As a page, what you're trying to do would be trivial. Remove all mark-up from the page, use Response.Headers to edit the response headers accordingly, Response.Write() to output your raw text, and Response.End() to close the response.

Use json

add the required attribute to your web service and your web method and you get what you want.

Web Service Attribute:[ScriptService]

Web Method Attribute:[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

Why do you want to get rid of the XML part? The code which is generated by the proxy needs a common format so it can understand and read the data that is being returned. Stripping the XML essentially makes your return data unreadable by the client proxy.
