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
