任何人都可以提供使用WinRT的XmlDocument.SelectSingleNodeNS函數的示例嗎?我不清楚第二個參數是什麼,我找不到一個例子。SelectSingleNodeNS中名稱空間參數的期望格式
public IXmlNode SelectSingleNodeNS(
string xpath,
object namespaces
)
Contains a string that specifies the namespaces to use in XPath expressions when it is necessary to define new namespaces externally. Namespaces are defined in the XML style, as a space-separated list of namespace declaration attributes. You can use this property to set the default namespace as well.
不,沒有性能損失。 採取在此[響應]看看[1] [1]:http://stackoverflow.com/questions/256859/is-there-a-performance-difference-between-a爲循環和爲每個循環 –
