有人可以帮我吗？

解决方案

上传完成后你应该保存已调整大小的图像和原始图像。



假设您将上传的图像保存在 Images / UserImages 中，然后您可以在图像/缩略图中保存上传图像的已调整大小的版本。您可以将图像大小调整为您想要的任何大小;代码项目中有很多文章。



之后你可以写html为



< pre lang =HTML> < a href =' / Images / UserImages / MyImage。 jpg>
< img src =' / Images / Thumbnail / MyImage.jpg / >
< / a >

因此，点击缩略图会将您重定向到您可以从中获取原始尺寸图像的图像路径。

解决方案

You should saved resized image along with original image after upload complete.

Say you would save uploaded image in Images/UserImages then you can save uploaded image's resized version in Images/Thumbnails. You can resize image to whatever size you want; there are number of articles in codeproject for that.

After that you can write html as

<a href='/Images/UserImages/MyImage.jpg">
 <img src='/Images/Thumbnail/MyImage.jpg" />
</a>

So clicking on thumbnail will redirect you to image path from where you can get original size image.
