Dim Cols1() As String = {"编码","EquipmentID","标志","dt_BeginDate","状态"} 如何定义表中无对应字段 值的组合呢?
Dim 标志 As String
Dim 编码 As String ="10010"
Dim 状态 As String
Dim Products As List(Of String)
Products = DataTables("m_Localizer").SQLGetValues("ID")
For Each Product As String In Products
'Output.Show(Product)
Dim dr As DataRow
dr = DataTables("Alarm_Current").Find("AlarmTypeID='1001' And EquipmentID='" & Product & "'")
If dr IsNot Nothing '如果找到, 则设置各列内容
标志="100"
状态="正常"
Else
标志="200"
状态="异常"
End If
Next
Dim c As Integer =DataTables("m_Localizer").Compute("count(vc_Name)")
output.show(c)
Dim Cols1() As String = {"编码","EquipmentID","标志","dt_BeginDate","状态"}
Dim s As String
s=Date.now() & "," & c
s = s.TrimStart(",")
FileSys.WriteAllText("D:\persionLoaction\Data\DeviceStatus.txt",s & vbcrlf,False)
For Each dr As DataRow In DataTables("m_Localizer").DataRows
s = ""
For i As Integer = 0 To Cols1.Length -1
If s > "" Then s = s & ","
If dr.IsNull(Cols1(i)) = False Then
s = s & dr(Cols1(i))
End If
Next
s = s.TrimStart(",")
FileSys.WriteAllText("D:\persionLoaction\Data\DeviceStatus.txt", s & vbcrlf , True, Encoding.Default)
Next
想实现如下内容输出,上述代码怎么修改呢?
