C# 无实体生成JSON字符串

string test = JsonConvert.SerializeObject(new
{
    UserCode = "TEST",
    Source = "TEST",
    DeviceTypeCode = "质量",
    DataRows = new object[]
       {
            new
            {
                ItemCode = "123123",
                DepartmentName="车间",
                PackName="",
                ProblemOperationCode="P0185-PZ-MB-001",
                ProblemOid= "8228bc0b-15a6-43d7",
                IsFillPlate = "false",
                ReworkProblemRemark="质量NG",
                ChargePerson = "",
                CheckPerson = "",
                CreateOperationCode = "PZ-MB-001"
            }
       }
