    出现这个错误的原因是,我的controller/action。

    action对应的方法,需要2个参数。但是post的时候,request body是一个json字符串。

    在目前不做parameter binding的情况下,直接将2个参数更改为1个参数JObject obj。

    然后在方法内部,对json字符串进行解析。

    dynamic json = obj;
    RedemptionInformationRequest parameters =
    JsonConverter.DeSerializer<RedemptionInformationRequest>(json.parameters.ToString());

    {
    "header": {
    "SecurityHash": "e1e7b4f072cfd5856a27a31640d5890bf3ccc5af7b5db810fc5e5906ee9f02bd"
    },
    "parameters": [
    {
    "TransactionId": "6117",
    "Result": "Accredited"
    },
    {
    "TransactionId": "6118",
    "Result": "Accepted"
    },
    {
    "TransactionId": "6119",
    "Result": "Error"
    }
    ]
    }

    json的数组是用[]表示的
