如何跳過DataGridViewRow？

Question

我行通過在一個DataGridView循環如下：

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 

我希望能跳到下一行，如果第一列是空的。我試過在If orow.Cells(0).Value.Length = 0中只使用Next，但是它引發了語法錯誤If must end with matching End If。有什麼建議麼？

Answer 1

你也可以只扭轉你的測試。

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

Answer 2

要跳到一個For，Do，或While循環的下一次迭代中，使用Continue像這樣：

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

'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
