c# - accéder à des fichiers téléchargés dans un gestionnaire générique - Stack Overflow

When I select a file and then submit I cant access the files that are supposed to be uploaded. There are a number of other statements in my handler function that didn't work either. I am using .NET 2.0, the error I am getting even though i have a file selected is the following:

"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"

I have the following form:

<form  runat="server" id = "selectFileForm" action="myDir/myHandler.ashx/fileUpload" method="POST"         enctype="multipart/form-data" />
    <input runat="server" type = 'file' id = 'fileUpload' multiple ='multiple'>
    <input type="hidden"  id = "cmd" name = "cmd" value=9>
</form>

I tried this with runat=server just on the form element and that didn't work. SO then I tried it also on the input element, neither way worked.

Here is what I have on the back end in my ashx:

private string fileUpload(HttpContext context)
{
    //foreach (string f in context.Request.Files.AllKeys)
    //{
    //    context.Request.Files[f].
    //}

    //HttpPostedFile fileupload = context.Request.Files[0];

    //return "{\"success\" : \"" + fileupload.FileName +"\"}";

    //return "{\"success\" : \"" + context.Request.Files["fileUpload"] +"\"}";

    return "{\"success\" : \"" + context.Request.Files[0] +"\"}";
}
