else
imgdefault.visible=false
end if
lblgreeting.text=txtgreeting.text
end sub
行 17： protected lblgreeting as label
行 18： protected lstborder as radiobuttonlist
行 19： protected imgdefault as image
行 20： protected withevents cmdupdate as button
“image”不明确，从命名空间或类型“System.Web.UI.WebControls, System.Drawing”导入
请问是什么问题？ 是由两个叫 Image 的类
要么
protected imgdefault as System.Drawing.Image
要么
protected imgdefault as System.Web.UI.WebControls谢谢,回答正确,呵呵!!
