.Net Core3.1 webapi如何接受java调用程序传入的复杂对象 Beanjson

Question

问题遇到的现象和发生背景

在学习JAVA调用.Net Core3.1 webapi时，不知道webapi如何接受较为复杂的对象数据，请专家指点。
我尝试写调用代码，不知道如何往下写了。
数据格式如下：

问题相关代码，请勿粘贴截图

这是java调用webapi时发送数据格式：

运行结果及报错内容

我的解答思路和尝试过的方法

我尝试写的webapi接受代码如下，写了一部分，不知道如何往下写了。

[HttpPost("PostSurface")]
        public IActionResult GetBeanjson([FromForm] dynamic obj)
        {
            #region  读取传入的参数
            dynamic objdyn = JsonConvert.DeserializeObject(Convert.ToString(obj));
            string _MPMProcessNumber = Convert.ToString(objdyn.MPMProcessNumber);                   
            string _TemplateNo = Convert.ToString(objdyn.TemplateNo);                 
            string _DrawingItemNumber = Convert.ToString(objdyn.DrawingItemNumber);                  
            string _PartNumber = Convert.ToString(objdyn.PartNumber);               
            string _PartName = Convert.ToString(objdyn.PartName);                 
            string _Structure = Convert.ToString(objdyn.Structure);                     
            string _Customer = Convert.ToString(objdyn.Customer);                
            string _RingType = Convert.ToString(objdyn.RingType);           
            string _SteelStrip = Convert.ToString(objdyn.SteelStrip);            
            string _ConfigurationParameter = Convert.ToString(objdyn.ConfigurationParameter);      
            string _ConfigurationRule = Convert.ToString(objdyn.ConfigurationRule);                         
            string _RingTemplateNo = Convert.ToString(objdyn.RingTemplateNo);                  
            string _RingTemplateValue = Convert.ToString(objdyn.RingTemplateValue);       
？？？？？？

我想要达到的结果

Answer 1

获取OperationBeanList吗？这个是数组，可以直接遍历获取

            foreach (var r in obj.OperationBeanList) {
                //(r.OperationNumber);
                //(r.OperationLabel);
            }
