将某些 PHP 转换为 C# 时遇到问题

Question

I'm a .NET developer, and (confession time) I've never used PHP for anything ever. I find myself needing to convert some PHP to test an API. I've converted much of it, bringing my error count from over 400 to 69, however, the further I go, the more convinced I am that it's just going to be broken.

So, I've decided to throw myself at the mercy of my fellow devs and ask for some help.

What I'm converting is this, a wrapper class that calls the API and returns XML or JSON.

<?php

class APIv2 {
protected $accessToken;
protected $baseURL;
protected $functions = array();
protected $format = 'json';

public function __construct($accountid, $key, $baseURL = 'https://www.eiseverywhere.com')
{
    $this->baseURL = rtrim($baseURL,'/').'/api/v2/';
    $request = $this->rawRequest($this->baseURL.'global/authorize.json',
                                  array('accountid' => $accountid,'key' => $key));
    $response = json_decode($request['response'], true);
    if (empty($response['accesstoken'])) {
        throw new \Exception(__CLASS__.': Bad url or parameters given. '.print_r($response,1));
    }
    $this->accessToken = $response['accesstoken'];
    $response = $this->rawRequest($this->baseURL.'global/listAvailableFunctions.json',
                                   array('accesstoken' => $this->accessToken));
    $functions = json_decode($response['response'], true);
    foreach ($functions as $sectionName=>$section) {
        foreach ($section as $methodName=>$functionArray) {
            foreach ($functionArray as $functionName) {
                $this->functions[$functionName] = array('method'=>$methodName, 'section'=>$sectionName);
            }
        }
    }
}

public function setFormat($format)
{
    $validFormats = array('xml','json');
    if (! in_array($format, $validFormats)) {
        $message = __CLASS__.": Invalid format: $format. Not one of the following:";
        foreach ($validFormats as $value) { 
            $message .= ' '.$value;
        }
        throw new \Exception($message);
    }
    $this->format = $format;
}

public function request($request, $parameters = array())
{
    $parameters['accesstoken'] = $this->accessToken;
    if (! array_key_exists($request, $this->functions)) {
        return array(
            'response' => '',
            'info' => $this->functions,
            'errors' => "Unknown function: $request",
        );
    }
    $function = $this->functions[$request];
    $url = $this->baseURL.$function['section'].'/'.$request.'.'.$this->format;
    return $this->rawRequest($url, $parameters, $function['method']);
}

public static function rawRequest($url, $parameters = array(), $method = 'get')
{
    $response = 'Unable to use etouches API, please enable cURL functionality (http://php.net/curl) for your server and try again';
    $info = '';
    $errors = '';
    $method = strtolower($method);
    if (function_exists('curl_init')) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
        $paramString = http_build_query($parameters);
        curl_setopt($ch, CURLOPT_URL, $url . (!empty($paramString)?'?'.$paramString:''));
        if ($method == 'post') {
            foreach ($parameters as &$value) {
                if (is_array($value)) {
                    $value = http_build_query($value);
                }
            }
            curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
        } else if ($method == 'put') {
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($paramString)));
            curl_setopt($ch, CURLOPT_POSTFIELDS, $paramString);
        }
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        $response = curl_exec($ch);
        $info = curl_getinfo($ch);
        $errors = curl_error($ch);

        curl_close($ch);
    }
    return array(
        'response' => $response,
        'info' => $info,
        'errors' => $errors
        );
}

}

function dump($h1, $var)
{
    echo "<h1>$h1</h1>";
    var_dump($var);
}

$api = new etouchesAPIv2($yourAccountId, $yourAPIKey);

$response = $api->request($call = 'listFolders');
$folders = json_decode($response['response'], true);
dump($call, $folders);

$parameters = array('name' => "New event created by etouches API",
                    'modules' => array('eHome','eMobile','eSelect','eReg','eBooth','eConnect','eSocial','eSeating'),);
if (count($folders)) {
    $parameters['folder'] = $folders[0]['folderid'];
}
$api->setFormat('xml');
$response = $api->request($call = 'createEvent', $parameters);
$newEvent = new SimpleXMLElement($response['response']);
dump($call, $newEvent);

$api->setFormat('json');
$response = $api->request($call = 'listEvents');
$events = json_decode($response['response'], true);
dump($call, $events);

$api->setFormat('xml');
$response = $api->request($call = 'listSpeakers', array('eventid' => $events[0]['eventid']));
$speakers = new SimpleXMLElement($response['response']);
dump($call, $speakers);

$response = $api->request($call = 'getEvent', array('eventid' => $events[0]['eventid']));
$event = new SimpleXMLElement($response['response']);
dump($call, $event);

$response = $api->request($call = 'cloneEvent', array('eventid' => $events[0]['eventid'],'name'=>"Event cloned via etouches API"));
$clonedEvent = new SimpleXMLElement($response['response']);
dump($call, $clonedEvent);

Where I'm having the most trouble, is the PHP method calls. I've been looking up c# equivalents to the best of my ability, but the final result just isn't pretty.

So, could you please refer me to some 'PHP to C#' tools or conversion references, or help me out with the CURLs, __CLASS__ , and other PHP specifics?

I should note, I've looked into Phalanger, and would prefer not to use it if possible. I also haven't found any comprehensive PHP to C# conversion tools or guides as of yet.

Thank you in advance!

EDIT:

As requested, here's my attempt at conversion (I know, it's messy, I'm not proud of it. Not fully converted, in flux.)
