如何格式化带有class参数的asp.net webmethod的JSON

我在我的asp.net代码后面有以下webmethod：

[WebMethod(EnableSession = true)]
public static bool SaveFailureData(SimpleFailureData data)
{

}

SimpleFailureData定义如下：

public class SimpleFailureData
{
    public int Id { get; set; }
    public string Comments { get; set; }
    public double score { get; set; }
    public double Adjustment { get; set; }
    public List<ShutdownData> ShutdownData { get; set; }
}

public class ShutdownData
{
    public int Id { get; set; }
    public string Description { get; set; }
    public bool CausedShutdown { get; set; }
    public string ShutdownType { get; set; }
}

我想弄清楚的是如何调用这个web方法并格式化我的数据,以便将它正确地投影/解析到该类中,以便我可以使用它.我尝试将json字符串发送到该方法,但我的方法中的断点从未被命中(因此我假设该方法由于数据格式不正确而无法调用).

这是我尝试发送然后调用该方法的JSON：

json = JSON.stringify( {
    Comments: comments,score: score,Adjustment: seAdjustmentValue,ShutdownData: breakdowns //this is an array of shutdown objects
});

PageMethods.SaveFailureData(json,function(data) {
    return;
});

但这未能进入我的方法.有关JSON格式应该是什么的任何提示,以便适当地将类作为参数传递？

这是我尝试发送给该方法的JSON：

{
"Comments":"","score":66.66666666666667,"Adjustment":0,"ShutdownData":[{"Id":"401","CausedShutdown":true,"ShutdownType":"norMAL"}]
}

解决方法

好吧试试这个

public static bool SaveFailureData(string sampleFailure)
    {
        JavaScriptSerializer s = new JavaScriptSerializer();
        SimpleFailureData sdata = s.Deserialize<SimpleFailureData>(sampleFailure);
        return true;
    }

    var json = {
                "Comments": "","score": 66.66666666666667,"Adjustment": 0,"ShutdownData": [{ "Id": "401","CausedShutdown": true,"ShutdownType": "norMAL"}]
            }

            var data = JSON.stringify(json);

            $.ajax({
                type: "POST",url: 'Default.aspx/SaveFailureData',contentType: 'application/json; charset=utf-8',data: "{'sampleFailure' : '" + data + "'}",// data: data,dataType: 'json',success: function (msg) {
                    alert(msg.d);
                },error: function (msg) {
                    alert('Error!');
                }
            });

        });

你将获得sdata对象中的数据.
