Select("name like '%hello%'");//支持like

Select("id>5","id desc");

Select("id>5", "id desc",DataViewRowState.Added)

DataRow[] dr = dt.Select(“col='XXXX'”);//条件：就是字段名='某某'

/// 执行DataTable中的查询返回新的DataTable

/// </summary>
/// <param name="dt">源数据DataTable</param>
/// <param name="condition">查询条件</param>
/// <returns></returns>
private DataTable GetNewDataTable(DataTable dt, string condition,string sortstr)
{
DataTable newdt = new DataTable();
newdt = dt.Clone();
DataRow[] dr = dt.Select(condition,sortstr);

if (dr== null || dr.Length == 0)  return null
for (int i = 0; i < dr.Length; i++)
{
newdt.ImportRow((DataRow)dr[i]);
}
return newdt;//返回的查询结果
}
