推荐答案

首先，并非文件夹中的所有文件都是图像，并且您试图将不是图像文件的文件加载到

First, not all files in your folder are images and you are attempting to load a file that is not an image file into

this.imageList1.Images.Add(Image.FromFile(file.FullName));

抛出file.FullName OutOfMemory异常中包含的字符串.

请参阅验证文件为JPEG的解决方案二 [

The the string contained in file.FullName an OutOfMemory Exception is thrown.

See solution two of Verifying a file is JPEG[^] on how to pick certain image files from a directory.

在.aspx中，您可以这样做:-

In .aspx u can do like this : -

<itemtemplate>
<img src="<%# Eval("path") %>" />
</itemtemplate>
