Answer 1

ok try this

    public static bool SaveFailureData(string sampleFailure)
    {
        JavaScriptSerializer s = new JavaScriptSerializer();
        SimpleFailureData sdata = s.Deserialize(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!');
                }
            });

        });

you will get the data in sdata object.
