遍历指定列名数据 发帖心情

Post By：2018/5/27 21:49:00 [只看该作者]

老师你好：

我的需求是：遍历指定列名数据，并按指定顺序进行排列，下面这代码出现了N个，如何处理？谢谢！

Dim dtb As DataTable = DataTables("试块取样")

Dim dr As Row = Tables("试块取样").Current

Dim nms() As String = {"品种种类","施工方量","供应商名称","设计强度","坍落度","试块留制_标准养护","试块留制_同条件养护","试块留制_拆模试块","取样人","见证人"}

Dim str As String

For Each dc As DataCol In dtb.DataCols

For i As Integer = 0 To nms.Length - 1

For Each nm As String In nms

If dc.Name = nm AndAlso dr.IsNull(nm) = False Then

str = str & dc.Name & ":" & dr(nms(i)) & ","

End If

MessageBox.Show(str)

有点甜
