图像上传-本地主机中断
我实现了一个小方法 对于我上传图像的网站。使用 FileUpload 控件，我选择一个图像，然后当我点击按钮时，会生成 UploadImage() 方法。
UploadImage() 方法将图像存储在服务器的文件夹中，并将其路径存储在数据库中。它还检查图像的文件大小，如果大于兆字节，则显示警报，否则上传并存储图像。已使用 45KB 到 900KB 的一些图像对此进行了测试。它运作得很完美。
问题：
当使用一些大约 4MB 的图像进行测试时，有时会显示“错误”，因为它大于 1MB，但有时（我不知道为什么），Google Chrome 会指示我到一个页面告诉我本地主机已被中断。
调试的时候我连按钮上传点击方法都不输入！我觉得这很奇怪。图像的扩展名似乎不是问题，因为我正在使用 .jpg 和 .png 进行测试。
有人遇到过同样的问题吗？有大师可以帮助我吗？
非常感谢。
更新：
4052kb 的文件似乎已正常工作（即显示错误消息） 但文件超过 4098kb）导致本地主机中断。当按钮被点击时， 下面的浏览器显示“发送请求”和上传 (0%)，并显示“与本地主机的连接已中断”。
I have implemented a small method
for my site where I upload an image. using a FileUpload control, I choose an image, and then when I hit a button, the UploadImage() method is generated.
The UploadImage() method stores the image in a folder in the server and stores its path in the Database. It also checks the file size of the image, if greater than a megabyte, an alert is displayed, else, the image is upload and stored. This has been tested with a few images ranging from 45KB to 900KB. It has worked perfectly.
THE PROBLEM:
When tested with a few images of approximately 4MB, sometimes it shows the 'error' since it is greater than 1MB, but at other times (I do not know why), Google Chrome directs me to a page telling me that the localhost has been interrupted.
When debugging, I do not even enter the button Upload click method! I find this very strange. The extension of the image doesn't seem to be the problem since I am testing with .jpg and .png.
Did some one experience the same problem? Is there a guru that can help me?
Thank you very much.
update:
it seems that files of 4052kb have worked correctly (i.e. an error message was displayed)
but files over 4098kb) resulted in a local host interrupt. When the button is clicked,
the browser below shows 'sending request' and uploading (0%) and displays "The connection to localhost was interrupted."

请查看
web.config的httpRuntime元素的maxRequestLength。http://msdn.microsoft.com/en-us/library/e1f13641.aspx
这是您设置最大请求长度的地方。当超过时，运行时会抛出异常。默认大小为 4096KB。
Please take a look at the
maxRequestLengthof thehttpRuntimeelement of theweb.config.http://msdn.microsoft.com/en-us/library/e1f13641.aspx
This is where you set the maximum request length. When it is exceeded, the runtime throws an exception. The default size is 4096KB.
