无法投射物体 [英] Unable to cast an object

问题描述

我想在一个窗口中显示多个图像文件.
我将在arraylist的帮助下存储文件，之后我将在arraylist的帮助下检索文件.
我正在使用binarywrite显示多个图像，但显示出无法投射对象的错误.

您能帮忙解决这个问题吗?

这是我的代码:

For i = 0 To fname1.Count - 1
                Response.Clear()
                Response.ContentType = "image/JPEG"
                Response.BinaryWrite(fname1(i))
                Response.Flush()
                Response.End()
            Next

在此先谢谢您.将文件名发送到页面...

查看File.ReadAllBytes，然后尝试发送该文件...

我也尝试过，但是在此过程中没有显示图像文件.

预先感谢

                Response.End()
            Next

解决方案

I''m just guessing here, but I don''t think that would work anyway: you probably want to read the file rather than sending the file name to the page...

Look at File.ReadAllBytes, and try sending that instead...

Hi,

I tried that too, but in this it not showing the image file.

Thanks in advance
