Question

请阅读此代码：

    Dim dt As New DataTable

    For Each col As DataControlField In GridView1.Columns
        dt.Columns.Add(col.HeaderText)
    Next

    For Each row As GridViewRow In GridView1.Rows
        Dim nrow As DataRow = dt.NewRow
        Dim z As Integer = 0
        For Each col As DataControlField In GridView1.Columns
            nrow(z) = row.Cells(z).Text.Replace("&nbsp;", "")
            z += 1
        Next
        dt.Rows.Add(nrow)
    Next

如何跳过gridview的某些列？例如：第1,3和6列

谢谢大家的时间！

Answer 1

Dim dt As New DataTable
For Each col As DataControlField In GridView1.Columns
If (col.Index <> 1) and (col.Index <> 3) and (col.Index <> 6) then
dt.Columns.Add(col.HeaderText)
End If
Next
For Each row As GridViewRow In GridView1.Rows
Dim nrow As DataRow = dt.NewRow
Dim z As Integer = 0
For Each col As DataControlField In GridView1.Columns
If (col.Index <> 1) and (col.Index <> 3) and (col.Index <> 6) then
nrow(z) = row.Cells(z).Text.Replace("&nbsp;", "")
z += 1
End If
Next
dt.Rows.Add(nrow)
Next

那不就是你想要的吗？

For-Each迭代器循环遍历每个元素，您可以过滤掉不需要的元素，如图所示。

或者，您可以创建一个包含要处理的所有索引的数组，并迭代该数组以仅处理仅包含所需索引的列。
