我正在尝试为 visual studio 构建输出添加颜色。所以我试图获得 IClassifierProvider 的分类器。但是 GetClassifier() 没有被调用。可能是什么问题呢？源代码示例如下。当我尝试使用 VSColorOutput 扩展时，它会启动。请告诉我我缺少什么？
[ContentType("output")]
[Export(typeof(IClassifierProvider))]
public class OutputClassifierProvider : IClassifierProvider
{
[Import]
internal IClassificationTypeRegistryService ClassificationRegistry;
[Import]
internal SVsServiceProvider ServiceProvider;
public static OutputClassifier OutputClassifier { get; private set; }
public IClassifier GetClassifier(ITextBuffer buffer)
{
MessageBox.Show("asd");
try
{
if (OutputClassifier == null)
{
OutputClassifier = new OutputClassifier();
}
}
catch (Exception ex)
{
throw;
}
return OutputClassifier;
}
}
public class OutputClassifier: IClassifier
{
public event EventHandler<ClassificationChangedEventArgs> ClassificationChanged;
public IList<ClassificationSpan> GetClassificationSpans(SnapshotSpan span)
{
return new List<ClassificationSpan>();
}
}

最佳答案
感谢 Jason Malinowski 我分析了 list 代码，发现那里缺少 MEF 内容。 将 MEF 添加到内容标签后，它现在可以工作了。
