vb.net中c#中的 o Is LinkButton 怎么写

[haonanernet]

我用c#翻译成vb.net
private void grid_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{

ListItemType elemType = e.Item.ItemType;
//定制分页导航行,样式为[1] [2] 第 3 页 [4]
if (elemType == ListItemType.Pager)
{

TableCell pager = (TableCell) e.Item.Controls[0];

for (int i=0; i<pager.Controls.Count; i+=2)
{
Object o = pager.Controls[i];
if (o is LinkButton)
{
LinkButton h = (LinkButton) o;
h.Text = "[ " + h.Text + " ]";
}
else
{
Label l = (Label) o;
l.Text = "第" + l.Text + “页”;
}
}
}
}
翻译代码如下:


Private Sub dgSortReport_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgSortReport.ItemCreated
If e.Item.ItemType = ListItemType.Pager Then
Dim pager As TableCell = CType(e.Item.Controls(0), TableCell)
Dim i As Integer
For i = 0 To pager.Controls.Count Step 2

Dim o As Object = CType(pager.Controls(i), Object)
If o Is LinkButton Then

Dim h As LinkButton = CType(o, LinkButton)
h.Text = "[ " + h.Text + " ]"

Else
Dim l As Label = CType(o, Label)
l.Text = "第" + l.Text + "页"
End If
Next i
End If
End Sub

其中 o Is LinkButton 报错说LinkButton是一种类型，不能用做表达式

那应该怎么写不错呢?请指教

用 o.GetType.Name 判断一下看

谢谢楼上,报同样的错

o is LinkButton

if typeof(o) is LinkButton then

end if
