c# 利用反射动态给实体类对象赋值

    /// <summary>
    /// 将datatable装入指定类型的集合
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class GenericList<T>:List<T>
    {
        public GenericList(DataTable dt, string  f)
        {
            System.Type tt = System.Type.GetType(f);//获取指定名称的类型
            object ff = Activator.CreateInstance(tt, null);//创建指定类型实例
            PropertyInfo[] fields = ff.GetType().GetProperties();//获取指定对象的所有公共属性
            foreach (DataRow dr in dt.Rows)
            {
                object obj = Activator.CreateInstance(tt, null);
                foreach (DataColumn dc in dt.Columns)
                {
                    foreach (PropertyInfo t in fields)
                    {
                        if (dc.ColumnName == t.Name)
                        {
                            t.SetValue(obj, dr[dc.ColumnName], null);//给对象赋值
                            continue;
                        }
                    }

                }
                this.Add((T)obj);//将对象填充到list集合
            }
        }
    }

//////////////////调用

 GenericList<Employee> list1 = new GenericList<Employee>(dt, "MvcApplication2.Models.Employee");//调用
  return View(list1);
