如何在C＃中合并来自DataTable的行数据？

Answer 1

我认为这是LINQ Group clause的一个很好的用例。你可以从这样的事情开始：

var rowGroups = dataTable.Rows.GroupBy(row => 
    new {RecptNo = row["recpt_no"], Test = row["Test"]});
foreach(var group in rowGroups) 
{
  //Here "group" is a collection of rows with the same rectp_no and test. Process as required.
  //You could also check group.Key.RecptNo and group.Key.Test here if necessary.
}
