I need a multiple file upload
FileIn of the uploaded file is named FileIn1, FileIn2 ...
Now I want to use a loop to implement the upload
How can I access existing objects?

HtmlInputFile file = (HtmlInputFile) this.FindControls ("FileIn" + i.ToString ());

Thank youshenmue024

But it should be HtmlInputFile file = (HtmlInputFile) this.FindControl ("FileIn" + i.ToString ())
You have one more "s"
