I won't talk about the theory, just look at the purchasing agent directly, and the code is more intuitive

The following is an example of the call
//使用方法如下：
string RecordFormID = Guid.NewGuid().ToString();
string Name="Name";
string Description = "Description";

dic.Add("RecordFormID", RecordFormID);
dic.Add(Name, FormOperatorService.SetNewRowFielName(CLDOverhaulRecordTableClone,Name));
