问题描述

在如果没有指定以上ASP.net Web服务，什么是默认响应格式？另外，如果我下面的Web服务：

In ASP.net web service if the above isn't specified , what is the response format by default?Also, if my web service below:

[WebMethod()]
        public List<Sample> GenerateSamples(string[][] data)
        {
            ResultsFactory f = new ResultsFactory(data);

            List<Sample> samples = f.GenerateSamples();
            return samples;
        }

返回对象的列表，如果我改变的响应格式为JSON，我必须要改变的返回类型为字符串，那我怎么访问我的JavaScript对象？

returns the list of objects, If I change the response format to JSON, I have to change the return type to string, then how do I access objects in my javascript?

目前我在JS调用这个Web服务，如：

Currently I call this web service in my JS such as:

 $.ajax({
    type: "POST",
    url: "http://localhost/TemplateWebService/Service.asmx/GenerateSamples",
        data: jsonText,

        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(response) {
            var samples = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d;

            if (samples.length > 0) {
                doSomethingHere(samples);
            } else {
                alert("No samples have been generated");
            }



        },

        error: function(xhr, status, error) {
            var msg = JSON.parse(xhr.responseText);
            alert(msg.Message);
        }

    });

我注意到，虽然，即使一切工作完全正常，eval语句永远不会被执行，这意味着网络服务始终返回一个字符串！

What i noticed though, even though everything works perfectly fine, the eval statement never gets executed, which means that the web service always returns a string!

所以我的问题是，是[ScriptMethod（ResponseFormat = ResponseFormat.Json）需要在Web服务定义的一面？

So my question is, is [ScriptMethod(ResponseFormat = ResponseFormat.Json)] necessary on the web service definition side?

该办法的事情，现在，我可以用的样品阵列和访问每个对象及其属性，我通常会在任何OOP code，这是非常方便的，而且一切正常没有问题，但我只是想确保我不会错过我的设置任何东西。

The way things are now, I can use samples array and access each object and its properties as I normally would in any OOP code, which is very convenient, and everything works no problem, but I just wanted to make sure that I am not missing anything in my set up.

我把结合jQuery的阿贾克斯与Encosia侧asp.net的基础知识，并响应类型中没有提到有 - 我读了它在其他网站和我我不知道这是多么重要。

I took the basics of combining Jquery's ajax with asp.net from Encosia side, and the response type wasn't mentioned there - I read it on another site and am I not sure how vital it is.

列出了asp.net web服务端4种不同的变化。我只有第2 - 在我的web.config。服务本身和样品类是没有任何序列化实现的，它确实有属性虽然。我猜的Web服务是JSON在默认情况下？而只要你的对象有属性，它们是序列化的默认？这是我的理解，直到我读了这篇文章。

Lists 4 different changes on the asp.net web service side. I only have the first 2 - in my web.config. The service itself and the Sample class is implemented without any serialization, it does have properties though. I guess the web service is JSON by default? And as long as your objects have properties, they are serializable by default? That was my understanding until I read this article.
