将DatatTab转为对应实体集合

public static List<T> ToList<T>(DataTable dataTable)
        {
            var columnNames = dataTable.Columns.Cast<DataColumn>()
                .Select(c => c.ColumnName)
                .ToList();

            var properties = typeof(T).GetProperties();

            return dataTable.AsEnumerable().Select(row =>
            {
                var objT = Activator.CreateInstance<T>();

                foreach (var pro in properties)
                {
                    if (columnNames.Contains(pro.Name))
                        pro.SetValue(objT, row[pro.Name]);
                }

                return objT;
            }).ToList();
        }
