问题描述

HI朋友，



如何将照片上传到aspx表单并在将照片保存到数据库之前同时显示它？



使用ajax或任何控件，请给我一个解决方案。

解决方案

 <   asp：FileUpload     ID   =  fileup1    runat   =  server   文字  = 浏览    /  >  
 
 string FilePath = fileup1 .PostedFile.FileName; 

其中''fileup1is''fileupload控件名称...

< blockquote>你好亲爱的，



你可以使用下面给出的图像控制 -



< asp ：image id =Image2runat =serverwidth =317height =104xmlns：asp =＃unknown>



上传后代码（当代码上传文件时）。你可以使用该文件如下例所示 -





imgstudy.ImageUrl = ImageNAme+？time =+ DateTime.Now.Ticks;



在图片网址中你必须用QueryString添加Tick。

它将给出正确的图像。

你好



你可以使用Ajax上传链接

Hello Dear ,

You Can use image control like given below--

<asp:image id="Image2" runat="server" width="317" height="104" xmlns:asp="#unknown">

After upload code (when code upload file at the location) .you can use that file Like this example below-


imgstudy.ImageUrl = "ImageNAme" + "?time=" + DateTime.Now.Ticks;

in the image url you have to add Tick with QueryString.
it will give correct image.

Hello

You can Use Ajax uploader Link
