.Net中FileUpload控件進(jìn)行多張圖片上傳
今天在解決多張圖片上傳時(shí),發(fā)現(xiàn)之前的單張上傳版本,
竟然是使用FileUpload服務(wù)器控件做的,
心想,這個(gè)修改起來就方便多了,哈哈 ,
下面直接貼出代碼了,包含頁(yè)面代碼,和.cs文件代碼,
附帶一個(gè)Demo演示項(xiàng)目,有什么不懂的可聯(lián)系站長(zhǎng)討論
注:控件
<asp:FileUpload ID="FileLoad" runat="server" multiple="multiple"></asp:FileUpload>
multiple="multiple" 這一句是關(guān)鍵哦,不加的話,無法選擇多張圖片
