De PHP a ASP.NET VB

Buenos días amigos Expertos de Cristalab, tengo un problema, necesito traducir este PHP y pasarlo a ASP.NET VB, ¿pueden ayudarme?

<?php


header("Cache-Control: no-cache, must-revalidate");
header('Content-Type: text/html; charset=UTF-8');

// Mime Creation
$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

// =============================================================================================================
// Open the upload files to be ready for the attachment
// =============================================================================================================
$tmp_name = $_FILES['Filedata']['tmp_name'];
$type = $_FILES['Filedata']['type'];
$name = $_FILES['Filedata']['name'];
$size = $_FILES['Filedata']['size'];

// if the upload succeeded, the file will exist
if (file_exists($tmp_name)){

// check to make sure that it is an uploaded file and not a system file
if(is_uploaded_file($tmp_name))
{

// open the file for a binary read
$file = fopen($tmp_name,'rb');

// read the file content into a variable
$data = fread($file,filesize($tmp_name));

// close the file
fclose($file);

// now we encode it and split it into acceptable length lines
$data = chunk_split(base64_encode($data));
}
}

// ============================================================================================================
// now we'll build the message headers
// ============================================================================================================
$remitente = "[email protected]";
$headers = "From:".$remitente."\r\n" . "MIME-Version: 1.0\r\n" . "Content-Type: multipart/mixed;\r\n" . " boundary=\"{$mime_boundary}\"";

// ============================================================================================================
// Message to send
// ============================================================================================================
$subject = "Asunto del mensaje";
$message.= "INFORMACION:\n";
$message.= "\Mensaje de parte de : ".$_REQUEST[nombre]."\n";

$message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"utf-8\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";

$message .= "--{$mime_boundary}\n" .
"Content-Type: {$type};\n" .
" name=\"{$name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";

// ============================================================================================================
// Send Email
// ============================================================================================================
// NOTE: in a real scenario you shouldn't send back the email to the sender,
// but you should set the customer email (i.e. [email protected] instead $_REQUEST[mail_txt])

if (@mail($_REQUEST[destinatario], $subject, ($message), $headers)){
// Return 1 if everything is ok and mail is sent
echo "1";
}
else {
// Return 0 if there are problems while sending mail
echo "0";
}


?>

Es de un formulario en flash, pero no tengo ni idea que como pasarlo.

Hey no hagas dobles post... mejormodificas o algo por el estilo
pero bueno mira te dire algo este foro de discucion es de php y mysql pero creo que para tranformar una sentencias php a asp.net o visual BAsic... creo que debes de saber de sintaxis sobre esos lenguajes si sabes haz de saber tranformarlo.... esa es mi opinion... y aqui no hay experto ejeje

Con todo respeto, si lo publico es porque no sé como hacerlo.
