要进行 XML 序列化，从 IEnumerable 继承的类型必须在其继承的所有级别都实现 ADD(System.Object) h

问题描述

我是 C# 新手，一直在修改前任员工编写的一些代码。如果我理解正确，并且我确定我没有理解，我需要向 MachineInfoClass 添加一个 Add 方法。它似乎已经接近尾声了。也许它的方法的范围不是公开的？非常感谢这位绿色 C# 程序员的帮助。

****这是在 xlmserializer 的 frmMain.CS 中实际弹出错误的地方 ****

 public bool SaveReport(string filePath)

                XmlSerializer xSave = new XmlSerializer(typeof(CalibrationReport));
                using (XmlWriter xWrite = XmlWriter.Create(filePath,ws))
                {
                    xSave.Serialize(xWrite,calReport);
