方法1

定義基類

        /// <summary>
        /// 克隆對象【[ExcludeCopy]排除】
        /// </summary>
public class BaseModel
    {
        public void Clone<T>(T dataObj)
        {
            var targetType = this.GetType();
            var dataType = dataObj.GetType();

            foreach (var p in dataType.GetProperties())
            {
                var tProperty = targetType.GetProperty(p.Name);

                if (null != tProperty)
                {
                    tProperty.SetValue(this, p.GetValue(dataObj, null), null);
                }
            }
        }
    }

//定義排除屬性
    public class ModelAttribute
    {
        public class ExcludeCopyAttribute : System.Attribute { }
    }

模型繼承基類

    public class Model : BaseModel<Model>
    {
        /// <summary>
        /// GUID
        /// </summary>
        public string GUID { get; set; }
        
    }

使用

  var model = new DrugModel
  {
       GUID = "1"
   };
   var copyModel = new Model();
   copyModel .Clone(drug);

        /// <typeparam name="T"></typeparam>

        public static void Clone<T>(this T target, T dataObj)
        {
            var targetType = target.GetType();
            var dataType = dataObj.GetType();

            foreach (var p in dataType.GetProperties())
            {
                var tProperty = targetType.GetProperty(p.Name);

                if (null != tProperty)
                {
                    tProperty.SetValue(target, p.GetValue(dataObj, null), null);
                }
            }
        }

        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="dataObj"></param>
        /// <returns></returns>
        public static T Clone<T>(this T dataObj) where T : new()
        {
            var target = new T();
            var targetType = target.GetType();
            var dataType = dataObj.GetType();

            foreach (var p in dataType.GetProperties())
            {
                var tProperty = targetType.GetProperty(p.Name);

                if (null != tProperty)
                {
                    tProperty.SetValue(target, p.GetValue(dataObj, null), null);
                }
            }

            return target;
        }

用法

//用法1(model2克隆model1數(shù)據(jù))
var model1= new Model();
...
var model2= new Model();
model2.Clone(model1);
//用法2（調(diào)用克隆方法返回一個新Model稻薇，直接接收就行了，這個感覺比較方便）
var m = model.Clone();
