问题描述

Hello All，



我在下面的代码中遇到上述错误。错误行也会突出显示：

Hello All,

I am getting the above error in the following piece of code. The row of error is also highlighted:

 	Dim Debittotal As Integer = 0
        Dim Credittotal As Integer = 0

        If grdDebit.RowCount > 1 Then
            For index As Integer = 0 To grdDebit.RowCount - 1
*****                Debittotal += Convert.ToDecimal(grdDebit.Rows(index).Cells(2).Value)
            Next
        End If

        If grdCredit.RowCount > 1 Then
            For index As Integer = 0 To grdCredit.RowCount - 1
                Credittotal += Convert.ToDecimal(grdCredit.Rows(index).Cells(2).Value)
            Next
        End If


        Dim NewfnBalance As Integer = Debittotal - Credittotal

提前致谢。

推荐答案

这告诉您没有三个Cell元素。如果我是你，我会在导致错误的行上设置一个断点，并查看 grdDebit.Rows（index）的值。我怀疑你所追求的价值是 Cells（1）。

This is telling you that you don't have three Cell elements. If I were you, I would put a breakpoint on the line that's causing the error and take a look at the values of grdDebit.Rows(index). I suspect the value you are after is in Cells(1).
