Response.Write("File: " & Server.HtmlEncode(arr1(loop1)) & "<br>")
Next loop1
int loop1;
HttpFileCollection Files;
Files = Request.Files; // Load File collection into HttpFileCollection variable.
arr1 = Files.AllKeys; // This will get names of all files into a string array.
for (loop1 = 0; loop1 < arr1.Length; loop1++)
{

int loop1;
HttpFileCollection files;
files = get_Request().get_Files(); // Load File collection into

var files : HttpFileCollection = Request.Files // Load File collection into HttpFileCollection variable.
