-- 请教学习手工编码填充数据中代码的问题
代码，请教老师！
Dim Cols1() As String = {"A表数据1","A表数据2","A表数据3"}
Dim Cols2() As String = {"B表数据1","B表数据2","B表数据3"}
For Each dr1 As DataRow In DataTables("表A").Select("A表数据2")
Dim dr2 As DataRow = DataTables("表B").AddNew()
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))
Next
Next
报错提示：筛选表达式“A表数据2”的计算结果不是布尔值项。
我所有的字段都是字符型。
再请教一个问题，怎样才能上传tables文件实例，在上传附件后看不到我的实例

参考
Dim Cols1() As String = {"A表数据1","A表数据2","A表数据3"}
Dim Cols2() As String = {"B表数据1","B表数据2","B表数据3"}
For Each dr1 As DataRow In DataTables("表A").Select("")
Dim dr2 As DataRow = DataTables("表B").Find("B表数据1 = \'" & dr1("A表数据1") & "\' and B表数据2 = \'" & dr1("A表数据2") & "\' and B表数据3 = \'" & dr1("A表数据3") & "\'")
If dr2 Is Nothing
dr2 = DataTables("表B").AddNew()
End If
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))
Next
Next

如果不想去重，就这样写
Dim Cols1() As String = {"A表数据1","A表数据2","A表数据3"}
Dim Cols2() As String = {"B表数据1","B表数据2","B表数据3"}
For Each dr1 As DataRow In DataTables("表A").Select("")
Dim dr2 As DataRow = DataTables("表B").AddNew()
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))
Next
Next
