如何在vb.net winodws应用程序中显示图像缩略图和删除选项 [英] How to Show image thumbnail and delete option in vb.net winodws application

问题描述

我正在面板中的vb.net winodws应用程序窗体中显示图像缩略图.
但是在使用功能
删除时

I am Showing image thumbnails in vb.net winodws application form in panel.
but while deleting with function

System.IO.File.Delete(finalunzipPath & "\001.jpg")

将异常显示为
该进程无法访问文件``D:\ TempUnZip \ Temp1 \ 01.jpg''，因为它正在被另一个进程使用.

但是，如果我从该位置手动删除该文件，则它将删除以编程方式删除文件的解决方案，例如我可以向用户提供删除文件选项. 有没有可用的教程，其中显示带有删除选项的图像缩略图..
我将图像对象用作

Showing exception as
The process cannot access the file ''D:\TempUnZip\Temp1\01.jpg'' because it is being used by another process.

But if i remove that file manually from that location then it deleted what is the solution to delete file programmatically such as i can provide delete file option to user..
is there any tutorial available where show image thmbnails with delete option..
I used image object as

imgThumb = img.GetThumbnailImage(115, 115, Nothing, New IntPtr())

用于生成缩略图，最后我正在做

for generating thumbnails and finally i am doing

img = Nothing
            objPic = Nothing
            imgThumb = Nothing

但是仍然存在问题

but still problem is coming

推荐答案

在执行
之前您要做什么?

what do u do before executing

System.IO.File.Delete(finalunzipPath & "\001.jpg")

确保您没有在任何先前的语句中打开文件.

Make sure you have not opened a file in any previous statement.
