巴克萊加密asp.net（VB到c＃）

Question

我正在嘗試從Barclays支付網關實現加密腳本，但它在VB中，我們網站的其余部分在c＃中。

腳本是

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

我怎樣才能在C＃aspx頁面中運行這個VB？ 或者我需要將其轉換為使用c＃?? 在我的aspx頁面中，我有第一行

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

謝謝你的幫助。

您的整個應用程序代碼都在C＃中。 因此，最好將巴克萊代碼轉換為C＃。 您可以使用以下鏈接將vb代碼轉換為C＃。 http://www.developerfusion.com/tools/convert/vb-to-csharp/

而不是在某個地方使用這個VB.NET代碼，轉換它會簡單得多; 而且，相信你會花時間消化它，我已經冒昧地為你這樣做了：

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);
    }
}

請注意，大部分代碼都是相同的，例如通過名稱空間看起來幾乎相同來訪問框架的類型; 差異包括區分大小寫，因此我們必須使用保留字的小寫字母，如訪問描述符（ public ， private等）和new關鍵字等等; 另外，語句在C＃中以分號結束。

此外，請注意您可能需要注意的代碼的一些“問題”，例如WebClient是一次性的 ，這里沒有正確處理的東西（也就是說，從不調用Dispose 。）
