c#之如何将对象序列化为 json 并将其发送到 Web 服务

如何将对象序列化为 json 并将其发送到 Web 服务？

var object = something.... 
function BindJson() { 
        $.ajax({ 
            type: "POST", 
            url: "NewPage.aspx/GetJson", 
            data: "{}", 
            contentType: "application/json", 
            dataType: "json", 
            success: function (data) { 
 
            } 
        }) 
    } 
 
<body onload="BindJson();"> 

服务器:

[WebMethod] 
        public static string GetSerializedJsonObject() 
        { 
            return ""; 
        } 

请您参考如下方法:

这对您有用(下面是完整的工作代码示例)。关键是传入一个Person对象。此外，我使用了一个简单的 Web 服务 (myService.asmx) 而不是 aspx 页面。如果不需要，为什么还要为额外的开销烦恼呢？

关键是，在客户端，创建一个Person对象然后使用JSON.stringify将 Person 对象传递给网络服务。

Javascript

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.js"></script> 
<script type="text/javascript"> 
    function BindJson() { 
        $.ajax({ 
            type: "POST", 
            url: "myService.asmx/SerializeJson", 
            data: JSON.stringify({ person:{ firstName: "Denny", lastName: "Cherian", department: "Microsoft PSS", address: { addressline1: "Microsoft India GTSC", addressline2: "PSS - DSI", city: "Bangalore", state: "Karnataka", country: "India", pin: "560028" }, technologies: ["IIS", "ASP.NET", "JavaScript", "AJAX"] }}), 
            contentType: "application/json; charset=utf-8", 
            dataType: "json", 
            success: function (data1) { 
                alert(data1.d); 
            }, 
            error: function (request, status, errorThrown) { 
                alert(status); 
            } 
        }); 
    } 
 
    $(document).ready(function() { 
        BindJson();     
    }); 
</script>
