如何将linq查询的结果 转换为DataTable,最简单的实现方法

public static DataTable CopyToDataTable(this IEnumerable array)
  {
  var ret = new DataTable();
  foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
  ret.Columns.Add(dp.Name, dp.PropertyType);
  foreach (T item in array)
  {
  var Row = ret.NewRow();
  foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
  Row[dp.Name] = dp.GetValue(item);
  ret.Rows.Add(Row);
  }
  return ret;
  }
