将自定义对象发送到asp.net Web服务

Question

So I want to send a custom object to an asp.net 4.0 Webservice.
I have been sending a bunch of individual parameters but i want to start reusing some code so I'd like to do something like

    [WebMethod(Description = "Testing Sending Object In")]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public bool COT(CodeWithMessage CWM)
    {
...

where the class for CodeWithMessage is

namespace UserSite
{
    namespace General
    {
        public class CodeWithMessage
        {
            public int iCode { get; set; }
            public string sMessage { get; set; }
            public CodeWithMessage()
            {
            }
        }
    }
}

The webservice defines the input as

    <?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
        <COT xmlns="http://localhost">
          <CWM>
            <iCode>int</iCode>
            <sMessage>string</sMessage>
          </CWM>
        </COT>
      </soap:Body>
    </soap:Envelope>

I tried passing the webservice the following json

      var postdata = { "iCode": -5, "sMessage": "BlogName " }

I get back an Internal Server Error [500]

{"Message":"Invalid JSON primitive: iCode."

Do I need to wrap this up somehow to indicate it is part of this object? I tried

{"__type":"UserSite.General.CodeWithMessage","iCode":-5,"sMessage":"Blog Name Already Exists"}

Which is what CodeWithMessage returns from another webservice that sends it instead of receiving it.

Answer 1

Your error says that you Json is wrong you need to check the json string you are passing to the webservice.

its may be like

var postdata = { 'iCode': '-5', 'sMessage': 'BlogName' }

check the jSon String example : http://www.json.org/js.html on jSon site........
