Convert Binary Read PHP Code To ASP

Can anyone help me convert the following php code to its asp equivalent? Code:

if(file_exists($file) && ($ext==".mp3"))
{
header("Content-Type: audio/mpeg3");

// open for binary read
$fh = fopen($file, "rb");

while (!feof($fh)) {
print (fread($fh, 10000));//filesize($file)));
}
fclose($fh);
}
else
{
print("ERORR: The file does not exist");
}
