Datagridview：如何更改隔天具有单元格值的交替行的颜色？

Question

尊敬的先生，我有一个 datagridview，在一列中填充了具有不同时间戳的数据

并尝试像上图那样在隔日范围内为行着色。到目前为止，我正在尝试这样

Private Sub alternateDaysRows()
        For i As Integer = 1 To Me.datagridview1.Rows.Count - 1
            If i > 1 Then
                Dim myLastRowDate As Date
                myLastRowDate = CType(Me.datagridview1.Rows(Me.datagridview1.Rows.Count - 1).Cells(2).Value, DateTime).Date
                myCountDate = myLastRowDate.AddDays(1)
                For Each row As DataGridViewRow In Me.datagridview1.Rows
                    If CType(row.Cells(2).Value, DateTime).Date = myCountDate Then
                        row.DefaultCellStyle.BackColor = Color.WhiteSmoke
                    End If
                Next
            End If
        Next
    End Sub

有什么建议吗？

按照这些思路可能会满足您的要求：

Private Sub alternateDaysRows()
    Dim myLastRow As DataGridViewRow = Nothing
    Dim myLastColor = Color.Yellow
    Dim isFirstRow As Boolean = True

    For Each row As DataGridViewRow In Me.DataGridView1.Rows
        If myLastRow IsNot Nothing Then
            If DateTime.Parse(myLastRow.Cells(0).Value.ToString).Date <> DateTime.Parse(row.Cells(0).Value.ToString).Date Then
                myLastColor = If(myLastColor = Color.Yellow, Color.Red, Color.Yellow)
            End If
        End If

        myLastRow = row
        row.DefaultCellStyle.BackColor = myLastColor
    Next

这假定单元格按日期顺序排序并且值可转换为日期。它会在日期更改时交替显示，而不是每隔一天显示一次，但会在查看不同日期时突出显示。
