2015-01-29 用户控件+swfupload引用资源路径出错

今天是周五，最近一直在忙碌，所谓忙碌就是将原来别人写好的代码移到新的地方，同时将里面使用 DexExpress换成repeater内容，再将之前的样式去掉 换成现在系统的样式。比较坑的是原来的代码所有 样式都在标签 内写的，我需要一行行找到去掉。在这里没有什么可说的，之中又遇到一个用户控件引用资源出错的问题，原来代码是使用绝对路径，现在想换成相对路径，但是查看后引用的位置总是不对，原来引用页面直接将用户控件的直接嵌入没有进行引用路径的转换，于是改为：

路径对了

对应的文件上传处理代码

                    {

                        // 文件名

                        for (int i = 0; i < context.Request.Files.Count; ++i)
                        {
                            file = context.Request.Files[i];
                            if (file == null || file.ContentLength == 0 || string.IsNullOrEmpty(file.FileName)) continue;

                            string fileExtension = new FileInfo(file.FileName).Extension.ToLower();

                            /// 将上传文件以不重复文件名形式保存到本站目录下
                            upFileName += dir + System.IO.Path.GetFileNameWithoutExtension(file.FileName) + "_" + fileId + fileExtension;
