我正在制作一个UWP（通用Windows平台）应用程序。我试图将
.xml.xsl.htmlXslCompiledTransform.xslMainPage.xaml.cs
private async void ConvertXML2HTML(IStorageFile xmlFile, IStorageFile xslFile)
{
Windows.Storage.Streams.IRandomAccessStream xslStream = await xslFile.OpenAsync(Windows.Storage.FileAccessMode.Read);
System.IO.Stream xslStreamNet = xslStream.AsStream();
XmlReader xmlReaderXsl = System.Xml.XmlReader.Create(xslStreamNet);
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load(xmlReaderXsl, settings, null); // This line throws
// System.PlatformNotSupportedException: 'Compilation of XSLT is not supported on this platform.'
}

上面代码中使用的xsl文件。

虽然我知道这不是 JScript 错误，但我尝试了下面的代码。没成功。
XslCompiledTransform xslt = new XslCompiledTransform();
var settings = new XsltSettings();
settings.EnableScript = true;
xslt.Load(xmlReaderXsl, settings, null);
您应该在 Windows.Data.Xml.Xsl 命名空间中使用类 XsltProcessor。在构造函数中传递对 XSLT 文件的引用。之后，调用方法 TransformToDocument 并向该方法传递对要转换的 XML 文件的引用。
