c#.net 将绝对路径转成相对路径

不是好方法！

因为工程里面没有根目录配置(web.config)所以只能获取当前目录

        /// <summary>
        ///  获取路径
        /// </summary>
        /// <param name="filespec">路径</param>
        /// <returns></returns>
        public string GetRelativePath(string filespec)
        {
            string rootPath = "";
            // 获取当前路径
            string BaseDirectoryPath = AppDomain.CurrentDomain.BaseDirectory;
            //  由于路径原因，向前倒三级
            rootPath = BaseDirectoryPath.Substring(0, BaseDirectoryPath.LastIndexOf("\\"));
            rootPath = rootPath.Substring(0, rootPath.LastIndexOf(@"\"));
            rootPath = rootPath.Substring(0, rootPath.LastIndexOf("\\")) + filespec;
            return rootPath;
        }

只能说是懒人方法了
