如何将输入的类型= QUOT;文件＆QUOT;到.NET文件上传？

我有一个使用标准形式现有的传统code。

I have existing legacy code that is using a standard form.

我想在后面抢code的句柄，这种输入类型=文件元素的页Init事件，并将其转换为一个.NET FileUpload对象。

I would like to in the page init event of the code behind grab a handle to this input type="file" element, and convert it to a .net fileUpload object.

这可能吗？而无需重写整个窗体？

Is this possible? Without rewriting the whole form?

先谢谢了。

编辑：不找如何处理上传处理，只是为了寻找切入点为例 - 怎么去输入类型=文件的引用，并把它作为一个.NET FileUpload对象。 - 再次感谢

Not looking for an example of how to handle the upload processing, just looking for the entry point - how to get a reference to the input type=file and treat it as a .net fileupload object. - Thanks again.

我的线沿线的思考

Dim myControl1 as FileUpload = FindControl("myFileElement")

这会工作，如果我能理清铸造问题？

Would this work if I could sort out the casting issue?
