最好用LINQ来XML API。它自 2007 年起在 .Net Framework 中可用。

这是您的起点。您可以扩展它以读取任何属性或元素。

        <CrossRateUSD>1.2954</CrossRateUSD>
        <CrossRateOther/>

    ...
</Tarih_Date>

c#

void Main()
{
    const string URL = @"https://www.tcmb.gov.tr/kurlar/today.xml";
    XDocument xdoc = XDocument.Load(URL);
    
    foreach (XElement elem in xdoc.Descendants("Currency"))
    {
        Console.WriteLine("CrossOrder: '{1}', Kod: '{1}', CurrencyCode: '{2}', Isim: '{3}', CurrencyName: '{4}'{0}"
            , Environment.NewLine
            , elem.Attribute("CrossOrder").Value
            , elem.Attribute("Kod").Value
            , elem.Attribute("CurrencyCode").Value
            , elem.Element("Isim").Value
            , elem.Element("CurrencyName").Value
            );
    }
}

输出

CrossOrder: '0', Kod: '0', CurrencyCode: 'USD', Isim: 'USD', CurrencyName: 'ABD DOLARI'

CrossOrder: '1', Kod: '1', CurrencyCode: 'AUD', Isim: 'AUD', CurrencyName: 'AVUSTRALYA DOLARI'
