When I run this webservice it gives me

Server Error in ‘/’ Application.

The XML element ‘SendCodeResponse’ from namespace ‘http://tempuri.org/’ references a method and a type. Change the method’s message name using WebMethodAttribute or change the type’s root element using the XmlRootAttribute.

Please help me.

Answer 1

Replace these 2 parts:

Part 1:

[Serializable]
public class SendCodeResponse
{
    string code;
    [XmlElement(Type = typeof(string), ElementName = "Code")]
    public string Code
    {
        get { return code; }
        set { code = value; }
    }
}

Part 2:

[WebMethod]
public SendCodeResponse SendCode(string userId, string barCode)
{
    SendCodeResponse scr = new SendCodeResponse();
    scr.code = "";
    return scr;
}

With:

New Part 1:

[Serializable]
public class SendCodeResult
{
    string code;
    [XmlElement(Type = typeof(string), ElementName = "Code")]
    public string Code
    {
        get { return code; }
        set { code = value; }
    }
}

New Part 2:

[WebMethod]
public SendCodeResult SendCode(string userId, string barCode)
{
    SendCodeResult scr = new SendCodeResult();
    scr.code = "";
    return scr;
}

As your WebMethod is called SendCode a type SendCodeResponse is automatically created, so you can’t make a class with that name.
