我从Excel文件导入数据,并且需要从2列中连接字符串值;如果它们不同,则将两个值都放在最后一列中,并更改字符串的颜色。我可以收集在DataGridView中显示的行,但是我不确定在哪里比较每行中的列以及如何比较它们。
我尝试了2个这样的循环来遍历行和列;
For Each row As DataGridViewRow In dgvTest.Rows
For Each column As DataGridViewColumn In dgvTest.Columns
Do While Not xlWorkSheet.Cells(i, 1).value = Nothing
Dim poid As Integer
Dim poid2 As Integer
Dim row As String() = New String() {xlWorkSheet.Cells(i, 1).value, xlWorkSheet.Cells(i, 2).value, xlWorkSheet.Cells(i, 3).value, xlWorkSheet.Cells(i, 4).value,
xlWorkSheet.Cells(i, 5).value, xlWorkSheet.Cells(i, 7).value, xlWorkSheet.Cells(i, 9).value, xlWorkSheet.Cells(i, 10).value, xlWorkSheet.Cells(i, 11).value, xlWorkSheet.Cells(i, 12).value, xlWorkSheet.Cells(i, 17).value}
dgvTest.Rows.Add(row)
i += 1
Loop
答案 0 :(得分:0)
这应该让您开始。
For Each DgvRow As DataGridViewRow In DataGridView1.Rows
If DgvRow.Cells("Column1").Value.ToString <> DgvRow.Cells("Column2").Value.ToString Then
DgvRow.Cells("Column3").Value = DgvRow.Cells("Column1").Value.ToString & DgvRow.Cells("Column2").Value.ToString
DgvRow.Cells("Column3").Style.BackColor = Color.Red
End If
Next
