使用.Net 4.0，ASP.NET類調用簡單的外部/ Web服務API

Question

從未在之前調用過API，也不確定要在ASP.NET 中使用哪些類來完成此操作。我大概可以通過閱讀 調用其他服務的各種示例，但希望有人可以 建議哪些將更加具體到我的需要，所以我可以快速開始 的東西。用PHP腳本調用這個API的一個例子位於下面，所以如果有人可以使用HttpWebRequest和WebClient打出 的一些代碼，看到它的行動將是偉大的 爲所述的例子，以及從API捕獲答覆HttpRequest的。也有可能使用Jscript從客戶端/瀏覽器調用這些API，或者這些調用是否必須從服務器端進行，並將結果傳遞給客戶端？

OUTPUT: The API will output the fields below: 

error If any error occurs while processing your request, this field will contain an error message. Otherwise, 'OK' will be returned. 
eta It's a string containing the Estimated Time of Arrival 
price The price charged to deliver the goods. GST is already included. 
Note that in the output, fields will be line-separated (character '\n') and each line will contain a field name and respective value separated by '='. See example below. 

error=OK 
eta=Overnight 
price=14.52 
The following piece of code is a simple example of how to access our Calculator API using PHP. 

<? 
$calculator_url = "http://www.e-go.com.au/calculatorAPI"; 

/* from/to postcodes */ 
$pickup = 2000; //From Sydney 
$delivery = 4000; //From Brisbane 

/* Dimensions */ 
$width = 40; 
$height = 35; 
$depth = 65; 
$weight = 2; 

$ego_params = "?pickup=$pickup&delivery=$delivery"; 
$ego_params .= "&width=$width"; 
$ego_params .= "&height=$height&depth=$depth&weight=$weight"; 
$ego_quote = file($calculator_url . $ego_params); 

foreach ($ego_quote as $num=>$quote) { 
    $quote = trim($quote); 
    $quote_field = explode("=", $quote); 
    print "Field=" . $quote_field[0] . "\tValue=" . $quote_field[1] . "\n"; 
} 
?>
