关于图片路径问题???

悬赏园豆：20 [已关闭问题]

我要实现将页面中指定的图片通过程序下载到本地磁盘中。我怎样获取这个图片的路径，后期发布时也不受影响，这个怎样写

.NET技术 ASP.NET

问题补充： WebClient webClient = new WebClient(); string str = @"http://"+System.Web.HttpContext.Current.Request.ServerVariables.Get("HTTP_HOST")+"/road.jpg"; webClient.DownloadFile(@"http://"+System.Web.HttpContext.Current.Request.ServerVariables.Get("HTTP_HOST")+"/road.jpg", @"E:\road.jpg"); object oMissing = System.Reflection.Missing.Value; object oEndOfDoc = "\\endofdoc "; /* \endofdoc is a predefined bookmark */ object name = "d:\\myfile.doc "; object Range = System.Reflection.Missing.Value; //Start Word and create a new document. Word.Application oWord; Word.Document oDoc; oWord = new Word.ApplicationClass(); oWord.Visible = true; oDoc = oWord.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing); oWord.Selection.Font.Bold = 1; oWord.Selection.Font.Size = 18; oWord.Selection.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter; oWord.Selection.InlineShapes.AddPicture("E:/road.jpg", ref oMissing, ref oMissing, ref Range); 我是用上述方法实现将图片存储到本地的，但在下面的图片获取中，我想让它灵活些，现在这个获取的不对 string str = @"http://"+System.Web.HttpContext.Current.Request.ServerVariables.Get("HTTP_HOST")+"/road.jpg";
