範例

下列程式碼範例示範如何呼叫 EncodeUrl 方法，以轉換 URL 中傳遞為方法呼叫中 AddAttribute 參數的任何空格。

// If an <anchor> element is rendered and an href
// attribute has not been defined, call the AddAttribute
// method to add an href attribute
// and set it to http://www.cohowinery.com.
// Use the EncodeUrl method to convert any spaces to %20.
if ( TagKey == HtmlTextWriterTag::A )
{
   if (  !IsAttributeDefined( HtmlTextWriterAttribute::Href ) )
   {
      AddAttribute( "href", EncodeUrl( "http://www.cohowinery.com" ) );
   }
}

// If an <anchor> element is rendered and an href
// attribute has not been defined, call the AddAttribute
// method to add an href attribute
// and set it to http://www.cohowinery.com.
// Use the EncodeUrl method to convert any spaces to %20.
if (TagKey == HtmlTextWriterTag.A)
{
    if (!IsAttributeDefined(HtmlTextWriterAttribute.Href))
    {
        AddAttribute("href", EncodeUrl("http://www.cohowinery.com"));
    }
}

' If an <anchor> element is rendered and an href
' attribute has not been defined, call the AddAttribute
' method to add an href attribute
' and set it to http://www.cohowinery.com.
' Use the EncodeUrl method to convert any spaces to %20.
If TagKey = HtmlTextWriterTag.A Then
    If Not IsAttributeDefined(HtmlTextWriterAttribute.Href) Then
        AddAttribute("href", EncodeUrl("http://www.cohowinery.com"))
    End If
End If

備註

字元的 URL 編碼是由百分比符號 (%) 所組成，後面接著字元的兩位數十六進位標記法 (不區分大小寫) 字元的ISO-Latin代碼點。 空間的十六進位標記法是 20。
