从ASMX Web服务返回JSON，而没有XML包装器？

用这个：

var JsonString = ....;$.ajax({    type: "POST",    contentType: "application/json; charset=utf-8",    url: "YourWebServiceName.asmx/yourmethodname",    data: "{'TheData':'" + JsonString + "'}",    dataType: "json",    success: function (msg) {        var data = msg.hasOwnProperty("d") ? msg.d : msg;        onSucessCallBack(data);    },    error: function (xhr, status, error) {        alert(xhr.statusText);    }});function onSuccessCallData(DataFromServer) { // your handler for success    }

然后在服务器端的AppCode文件夹中自动生成的文件背后的代码中，您将编写如下内容：

using System.Web.Services;using System.Web.script.Serialization;    [System.Web.script.Services.scriptService]    public class YourWebServiceName : System.Web.Services.WebService    {        [WebMethod]        public string yourmethodname(string TheData)        {          JavascriptSerializer YourSerializer = new JavascriptSerializer();          // custom serializer if you need oneYourSerializer.RegisterConverters(new JavascriptConverter  [] { new YourCustomConverter() });          //deserialization          TheData.Deserialize(TheData);          //serialization TheData.Serialize(TheData);        }    }

如果不使用自定义转换器，则服务器端对象的json字符串和c＃类定义之间的属性必须匹配，才能进行反序列化。对于序列化，如果没有自定义转换器，则json字符串将包含c＃类的每个属性。您可以
