A页面:
<asp:FileUpload ID="load_img" runat="server" />
<input name="btn_save" type="button" value="保存" runat="server" onserverclick="btn_save_ServerClick" />
protected void btn_save_ServerClick(object sender, EventArgs e)

展开全部
img_headimg.ImageUrl = Server.MapPath("../img/headimg/1.png");
修改为
img_headimg.ImageUrl = "../img/headimg/1.png";
Server.MapPath是把虚拟地址映射为服务器实际地址。保存时,是保存到实际地址。
但是显示时,显示的虚拟地址。
