Question

输入json

{
    "ErrorMessage":"Transaction has been authorized successfully",
    "ControlId":1000.00,
    "Authorizations":[
        {
            "RMATranUUID":"1c1a88f7-d6cf-4ae8-87d3-ba06e9d9fe36",
            "Payments":[
                {
                    "PaymentNumber":"1",
                    "TotalPaymentsNumber":24,
                    "AmountDue":1000.0,
                    "AmountPaid":0.00
                }
            ],
            "Term":24,
            "OTBReleaseAmount":null
        },
        {
            "RMATranUUID":"b012ba9c-2dbd-4961-8959-ec0afbafbe13",
            "OTBReleaseAmount":null
        }
    ]
}

解析后输出json

        JObject jsonPacket = JObject.Parse(inputString);

//行无变化，从1000.00更改为1000.0

{
    "ErrorMessage":"Transaction has been authorized successfully",
    "ControlId":1000.0,
    "Authorizations":[
        {
            "RMATranUUID":"1c1a88f7-d6cf-4ae8-87d3-ba06e9d9fe36",
            "Payments":[
                {
                    "PaymentNumber":"1",
                    "TotalPaymentsNumber":24,
                    "AmountDue":1000.0,
                    "AmountPaid":0.00
                }
            ],
            "Term":24,
            "OTBReleaseAmount":null
        },
        {
            "RMATranUUID":"b012ba9c-2dbd-4961-8959-ec0afbafbe13",
            "OTBReleaseAmount":null
        }
    ]
}

原因是解析双精度的JObject在后台执行如下操作：

double data;
double.TryParse("1214.00", NumberStyles.Float | NumberStyles.AllowThousands, CultureInfo.InvariantCulture, out data);

由于数据的类型为double，double是浮点数，因此您没有获得期望的值。

您可以创建一个POCO并将其解析为它，或者可以执行以下操作：

string json = "{    \"ErrorMessage\":\"Transaction has been authorized successfully\",    \"ControlId\":1000.00,    \"Authorizations\":[        {            \"RMATranUUID\":\"1c1a88f7-d6cf-4ae8-87d3-ba06e9d9fe36\",            \"Payments\":[                {                    \"PaymentNumber\":\"1\",                    \"TotalPaymentsNumber\":24,                    \"AmountDue\":1000.0,                    \"AmountPaid\":0.00                }            ],            \"Term\":24,            \"OTBReleaseAmount\":null        },        {            \"RMATranUUID\":\"b012ba9c-2dbd-4961-8959-ec0afbafbe13\",            \"OTBReleaseAmount\":null        }    ]}";

var jsonReader = new JsonTextReader(new StringReader(json));
jsonReader.FloatParseHandling = FloatParseHandling.Decimal;

var jObject = JObject.Load(jsonReader);

Console.WriteLine(jObject["ControlId"].Value<decimal>()); // 1000.00
Console.WriteLine(jObject); // prints your actual json

将字符串解析为JObject
