Integrate CCAvenanu Payment Gateway to Dot net core api 2.0?

Question

HI folks,

 

I would like to integrate ccavenue payment gateway to andriod application. For request and response processing we are using backend dot net core web api 2.1. But I did't find any reference for dot net core application. Can any one help me out to get out of this.

 

I will add the code what they are give for request and respose processing files.

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections;
using System.Collections.Specialized;
using CCA.Util;
public partial class ResponseHandler : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string workingKey = "6D108E9180E34A8B9FA6350B59108071";//put in the 32bit alpha numeric key in the quotes provided here
CCACrypto ccaCrypto = new CCACrypto();
string encResponse = ccaCrypto.Decrypt(Request.Form["encResp"],workingKey);
NameValueCollection Params = new NameValueCollection();
string[] segments = encResponse.Split('&');
foreach (string seg in segments)
{
string[] parts = seg.Split('=');
if (parts.Length > 0)
{
string Key = parts[0].Trim();
string Value = parts[1].Trim();
Params.Add(Key, Value);
}
}
for (int i = 0; i < Params.Count; i++)
{
Response.Write(Params.Keys[i] + " = " + Params[i] + "<br>");
}
}
}

namespace GetRSA_Kit
{
public partial class GetRSA : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
string queryUrl = "https://secure.ccavenue.com/transaction/getRSAKey";
string vParams = "";
foreach (string key in Request.Params.AllKeys){
vParams += key + "=" + Request[key] + "&";
}
// Url Connection
String message = postPaymentRequestToGateway(queryUrl, vParams);
Response.Write(message);
}
catch (Exception exp){
Response.Write("Exception " + exp);
}
}
private string postPaymentRequestToGateway(String queryUrl, String urlParam)
{
String message = "";
try
{
StreamWriter myWriter = null;// it will open a http connection with provided url
WebRequest objRequest = WebRequest.Create(queryUrl);//send data using objxmlhttp object
objRequest.Method = "POST";
//objRequest.ContentLength = TranRequest.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";//to set content type
myWriter = new System.IO.StreamWriter(objRequest.GetRequestStream());
myWriter.Write(urlParam);//send data
myWriter.Close();//closed the myWriter object
// Getting Response
System.Net.HttpWebResponse objResponse = (System.Net.HttpWebResponse)objRequest.GetResponse();//receive the responce from objxmlhttp object
using (System.IO.StreamReader sr = new System.IO.StreamReader(objResponse.GetResponseStream()))
{
message = sr.ReadToEnd();
}
}
catch (Exception exception)
{
Console.Write("Exception occured while connection." + exception);
}
return message;
}
}
}

Thanks in advance
