在运行时加载图像. [英] Load image at run-time.

问题描述

大家好.

我是ASP.net的新手，正在学习它.我创建了一个页面，并在页面上放置了文件上传工具，图像控件和按钮.当我浏览图像并单击btn以在该图像控件上显示该图像时，它不起作用.

我在button_click事件中使用了以下代码:

Hi all.

I am new to ASP.net and learning it. I created a page and put a file upload tool, an image control and a button on page. When I browse an image and click on btn to show that image on that image control, it does not work.

I used the below code in button_click event :

if fileUpload1.HasFile then
imageControl.imageUrl=fileUpload1.PostedFile.FileName
end if

建议我该怎么办.

谢谢.

推荐答案

您需要将文件数据保存到服务器上的文件中，然后将ImageUrl指向该路径，而不仅仅是指向上传的文件的名称.

You need to save the file data to a file on the server, then point the ImageUrl to that path rather than just to the name of the file that was uploaded.

感谢您的回答.

因为我是asp.net的新手，所以请您详细说明您的答案.

谢谢.
