图片上传控件

只需设置上传路径即可实现无刷新上传图片 public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; HttpPostedFile file = context.Request.Files["Filedata"];//获取上传的文件. string fileName = Path.GetFileName(file.FileName); //获取文件名称. string fileExtion = Path.GetExtension(file.FileName);//获取扩展名. if (fileExtion == ".jpg" || fileExtion == "gif") { //file.SaveAs(context.Server.MapPath("/FileUp/" + fileName)); //context.Response.Write("ok:/FileUp/" + fileName); string saveDir = "/FileUp/" + DateTime.Now.Year + "/" + DateTime.Now.Month + "/" + DateTime.Now.Day + "/"; Directory.CreateDirectory(Path.GetDirectoryName(context.Server.MapPath(saveDir)));//建立文件夹 string fullDir = saveDir + Common.Common.GetStreamMD5(file.InputStream) + fileExtion;//将文件进行MD5运算作为新的文件的名称. file.SaveAs(context.Server.MapPath(fullDir)); context.Response.Write("ok:" + fullDir); //这里做保存到数据库处理 } else { throw new Exception("类型错误!"); } }
