C#将list转换为datatable

 DataTable dt = new DataTable();
 if (_list != null)
 {
      //通过反射获取list中的字段 
    System.Reflection.PropertyInfo[] p = _list[].GetType().GetProperties();
    foreach (System.Reflection.PropertyInfo pi in p)
     {
       dt.Columns.Add(pi.Name, System.Type.GetType(pi.PropertyType.ToString()));
     }
    for (int i = ; i < _list.Count; i++)
    {
        IList TempList = new ArrayList();
         //将IList中的一条记录写入ArrayList
        foreach (System.Reflection.PropertyInfo pi in p)
        {
          object oo = pi.GetValue(_list[i], null);
          TempList.Add(oo);
        }
       object[] itm = new object[p.Length];
      for (int j = ; j < TempList.Count; j++)
      {
        itm.SetValue(TempList[j], j);
      }
      dt.LoadDataRow(itm, true);
       }
 }
