主题：表内数据重复

方法一：

方法二：

Dim idx As String = "-1,"
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing
Dim count As Integer = 0
Dim cs As String = "第一列,第二列"
For Each dr As DataRow In DataTables("表A").Select("", cs)
    Dim flag As Boolean = False
    If pdr IsNot Nothing Then
        For Each c As String In cs.split(",")
            If pdr(c) <> dr(c) Then
                flag = True
                Exit For
            End If
        Next
        If flag Then
            If count > 1 Then
                idx &= idx_temp
            End If
            count = 1
            idx_temp = ""
        Else
            count += 1
            idx_temp &= dr("_Identify") & ","
        End If
    Else
        count += 1
    End If
    pdr = dr
Next

If count > 1 Then
    idx &= idx_temp
End If

Tables("表A").Filter = "_Identify not In (" & idx.trim(",") & ")"

'DataTables("表A").DeleteFor("_Identify not In (" & idx.trim(",") & ")")

倒数第二行的语句，只是把重复的数据筛选成只显示一条，并没有做到删除的作用。

我把倒数第二行注释了，把倒数第一行调用出来，虽然可以删除了，但是一次只能删除一条。

而且重复数据删除只剩一条时，在点一下删除按钮，会把最后一条也删除了，有没有比较好的解决方法？
