巴克莱加密asp.net (VB到c#)

我正试图实现从巴克莱支付网关的加密脚本，但它是在VB和我们的网站的其余部分是在c#。

脚本是

Public Class Example
    Inherits System.Web.UI.Page
#Region " Web Form Designer Generated Code "
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
    End Sub
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
    End Sub
#End Region
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
       'The Following Creates the WebClient Object
        Dim web As New System.Net.WebClient()
       'The Header Content Type is then set 
        web.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
       'PostData is then declared as data type Byte and populated with the post data 
        Dim PostData As Byte() = System.Text.Encoding.ASCII.GetBytes("clientid=[clientid]&password=[password]&oid=[orderid]&chargetype=PreAuth&currencycode=826&total=[total]")
        'The Web object is then used to upload the postdata to the Encryption URL and the response is stored in the Response variable
        Dim Response As Byte() = web.UploadData("https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdqEncTool.e", "POST", PostData)
        'The response from the post is then converted from Type Byte to String and stored in the session variable
        Session("Response") = (System.Text.Encoding.ASCII.GetString(Response))
    End Sub
 End Class

我如何能够运行这个VB在我的c# aspx页面?或者我需要将其转换为使用c#?在我的aspx页面中，第一行是

<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="utf-8" CodeBehind="encryption.cs" %>

谢谢你的帮助

public class Example : System.Web.UI.Page
{
    private void Page_Load(object sender, System.EventArgs e)
    {
        //put user code to initialise page here
        var client = new System.Net.WebClient();
        client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
        var data = System.Text.Encoding.ASCII.GetBytes(
            "clientid=[clientid]&password=[password]&oid=[orderid]&" + 
            "chargetype=PreAuth&currencycode=826&total=[total]");
        var response = client.UploadData(
            "https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdqEncTool.e", 
            "POST", data);
        Session["Response"] = System.Text.Encoding.ASCII.GetString(response);
    }
}
