C#DataTable转List<Models>

调用:

List<BASEINFO> mar = DataTableToIList<BASEINFO>(myData.Tables[0]).ToList<BASEINFO>();
DataTableToIList方法:
 /// <summary>
        /// DataTable转为List<T>
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="table"></param>
        /// <returns></returns>
        public static IList<T> DataTableToIList<T>(DataTable table)
        {
            IList<T> result = new List<T>();

            for (int j = 0; j < table.Rows.Count; j++)
            {
                T _t = (T)Activator.CreateInstance(typeof(T));
                PropertyInfo[] propertys = _t.GetType().GetProperties();

                foreach (PropertyInfo p in propertys)
                {

                    //Type t = p.PropertyType;
                    //MethodInfo m = t.GetMethod("TryParse");
                    switch (p.PropertyType.Name)
                    {
