從iPhone使用Web服務錯誤

Question

我一直在關注教程http://iphonebyradix.blogspot.ca/2011/04/working-with-webservices.html，並決定使用xaramin創建自己的Web服務並嘗試調用它。但它似乎並沒有因某種原因而被召喚。

Service1.asmx 
[WebMethod] 
public string printsomeThing(string userData){ 
    Console.WriteLine("test"); 
    Console.Out.WriteLine(); 
    return userData; 
} 

POST /Service1.asmx 
SOAPAction: http://tempuri.org/printsomeThing 
Content-Type: text/xml; charset=utf-8 
Content-Length: string 
Host: string 

<?xml version="1.0" encoding="utf-16"?>

    <printsomeThing xmlns="http://tempuri.org/"> 
     <userData>string</userData> 
    </printsomeThing> 
    </soap:Body> 
</soap:Envelope>

它說，我的消息得到了發送，但我的web服務沒有收到它雖然

我與編碼發揮各地以及自肥皂消息字符集是UTF 8，它的編碼是16，但似乎工作要麼

喲ü正在收到你的服務器的迴應，如日誌所示：

Received Bytes: 44115 

所以，絕對是服務器上的問題。 它回覆，但請求沒有路由到正確的頁面，所以它是錯誤的頁面回覆。

檢查theXML的內容以瞭解哪個頁面正在回覆，可能是某種404頁面或類似內容。
