C#上传图片到数据库问题

来源：互联网发布：淘宝标题在线优化工具编辑：程序博客网时间：2024/05/20 22:38

        我用C#写了一段上传图片到数据库的代码,思路是:把图片上传到指定文件夹,然后把路径发送到数据库中,显示这个图片时,直接从数据库中读取路径来显示图片,网上找了很久,都不行.我用C#写的代码,很简单的几句,上传的功能已进ok了,但是把路径写入数据库这个环节还有点问题.
        我的思路: (upload.aspx) 上传图片-->获取路径-->向数据库写入路径
                           pic.asp(显示图片页)    读取图片路径-->src="###"
       目前C#不是很熟悉,所以用了asp和C#合用的手法,上传用C#,显示用asp
