jQuery文件上传插件（BackLoad）：如何限制文件的数量和大小？

Question

I'm using JQuery File Upload plugin with BackLoad for uploading files in MVC4 application. The upload works fine. However, I could not figure out a way to limit the # and size of files. Can we do this in the plugin?

Now, user can add as many files (images) as they want and file size can be very large. I only want to allow them upload 1 file and size < 10MB at a time.

I tried to change the template-upload to show just one file, but it does not work. It seems when multiple files are selected, the template-upload will be used multiple times. Each time, files only has one file.

I also changed maxFileSize in Backload.Default.config , but it does not work. It seems it is for images that are already uploaded.

Before I used Ajax toolbox in web form, and they can be done easily. Now, I'm trying this in mvc4 application, any idea of how to achieve these?

Thanks

设置属性maxFileSize：5000000，// 5mb和maxNumberOfFiles：1将在客户端影响它。
