是否可以爲Web服務請求輸入參數分配默認值

我想知道是否可以爲Web服務請求輸入參數分配默認值。下面是在WSDL我的輸入參數：是否可以爲Web服務請求輸入參數分配默認值

<element name="pensionType" default="0" type="int">

在代碼方面我檢查pensionType像這樣的值：

if (pensionType!=0) 
{ TODO code here} 
else 
{ return warning that no data found}

我在Mozilla測試海報此。因此，我預計如果我沒有給養老金提供任何價值，我會得到這個警告。我弄了半天錯誤：

你可以這樣做：

if(pensionType != null) 
{ 
    if (pensionType!=0) 
    { TODO code here} 
    else 
    { return warning that no data found} 
}

這可能會幫助你.. !!
