Android访问C#的WebService要注意的问题

@Override
protected String doInBackground(Object... params) {
    // 根据命名空间和方法得到SoapObject对象
    SoapObject soapObject = new SoapObject(targetNameSpace, getSimpleProductByBarcode);　　// 命名空间就是WebService代码文件里的 [WebService(Namespace = "http://tempuri.org/")] 这个，最好不要用默认的

    // 通过SOAP1.1协议得到envelop对象
    SoapSerializationEnvelope envelop = new SoapSerializationEnvelope(SoapEnvelope.VER11);　　// 一定要确认版本，版本不对将报错

    // 将soapObject对象设置为envelop对象，传出消息
    envelop.dotNet = true;
    envelop.setOutputSoapObject(soapObject);
    // 或者envelop.bodyOut = soapObject;

    // 设置参数
    soapObject.addProperty("barcode", params[0]);

    HttpTransportSE httpSE = new HttpTransportSE(WSDL);

    // 开始调用远程方法
    try {
        httpSE.call(targetNameSpace + getSimpleProductByBarcode, envelop);
        // 得到远程方法返回的SOAP对象
　　　　 // 如果以SoapObject来转换发生错误，就要试着以SoapPrimitive来转换
        SoapPrimitive resultObj = (SoapPrimitive) envelop.getResponse();
        if (resultObj != null)
            scan_result = String.valueOf(resultObj.toString());
    } catch (IOException e) {
        e.printStackTrace();
        return "IOException";
    } catch (XmlPullParserException e) {
        e.printStackTrace();
        return "XmlPullParserException";
    }
    return "success";
}
