vb.net - 如何跳过 DataGridViewRow？

Question

我正在遍历 DataGridView 中的行，如下所示：

For Each orow As DataGridViewRow In GV_NS.Rows
    If orow.Cells(0).Value.Length = 0 Then
        //Skip this row and go to next row
    Else
        //do this
    End If
Next

如果第一列为空，我希望能够跳到下一行。我尝试只使用Nextin If orow.Cells(0).Value.Length = 0，但它抛出了语法错误If must end with matching End If。有什么建议么？

Answer 1

要跳到、 或循环的下一次迭代，For请像这样使用：DoWhileContinue

For Each orow As DataGridViewRow In GV_NS.Rows
    If orow.Cells(0).Value.Length = 0 Then
        //Skip this row and go to next row
        Continue For
    Else
        //do this
    End If
Next

Answer 2

您也可以只反转您的测试。

For Each orow As DataGridViewRow In GV_NS.Rows
    If orow.Cells(0).Value.Length <> 0 Then
        //do this
    End If
Next

    'Filter rows with LINQ
    Dim Query = From row In GV_NS.Rows
        Where CType(row, DataGridViewRow).Cells(0).Value.ToString.Length > 0
        Select row
    For Each Row As DataGridViewRow In CType(Query.ToArray, DataGridViewRow())
        'Do something
    Next
