问题描述

如何访问平板电脑文件夹以检索图片？



例如：



说我已经为我的网站编写了一个应用程序，允许我输入数据和图像。现在我正从我的平板电脑浏览我的网站，我想用我的平板电脑拍照，但我希望那张照片出现在应用程序的文本区域？或者至少让我的应用程序从平板电脑上的文件夹中获取我刚刚拍摄的照片。



是否有人有任何关于我或如何完成任何信息的例子这个？

How can I access a tablets folder to retrieve a picture?

For example:

say I have written an application for my website that allows me to enter data and also images. Now I am browsing on my website from my tablet and I want to take a picture with my tablet, but I want that picture to appear in my text area of the application? or at least have my application get the picture I just took from the folder on the tablet.

does anyone have any examples of this or any information on how I can accomplish this?

推荐答案

好的，我想你需要检索上传的图片，这是从平板电脑上传的吗？ ，那么你需要将它查看到文本区域吗？



如果这是你的问题，我认为你不能将图像显示到文本框中，但你可以将它显示到标签中。



如果您需要知道将其上传到数据库然后检索它，请检查此链接：

您可以通过此代码库在提到的链接上将该图像检索到标签中。

If e.Row.RowType = DataControlRowType.DataRow Then

       Dim base64String As String = Convert.ToBase64String(bytes, 0, bytes.Length)
  Labal1.text =  ""

   End If
