c# - 在 Visual Studio 2010 中突出显示转到

Question

我目前正在翻译旧生成的 C# 代码，其中充满了 goto。请不要对此发表评论，我知道这很糟糕。无论如何，有没有办法/扩展/任何使 goto-statements 更具可读性的方法？很难找到代码跳转的地方。我不想使用搜索功能，因为它会让我迷失方向。

我只找到了这个: http://visualstudiogallery.msdn.microsoft.com/4b286b9c-4dd5-416b-b143-e31d36dc622b它不起作用。

你能推荐什么吗？

可能有点晚了，但您可以使用 Visual Studio 可扩展性构建您自己的(因此也可以添加自定义行为):Inside the Editor: Tags and Classifier .步骤是:

1)创建一个Editor Classifier项目(内置项目类型)

2) 删除现有类文件

3) 添加下面的代码。它将代码部分中的所有“goto”语句着色为红色:

internal class GotoTagger : ITagger<GotoTag>
{
    private ITextSearchService _textSearchService;
    private ITextStructureNavigator _textStructureNavigator;

    event EventHandler<SnapshotSpanEventArgs> ITagger<GotoTag>.TagsChanged { add { } remove { } }

    public GotoTagger(ITextSearchService textSearchService, ITextStructureNavigator textStructureNavigator)
    {
        _textSearchService = textSearchService;
        _textStructureNavigator = textStructureNavigator;
    }

    public IEnumerable<ITagSpan<GotoTag>> GetTags(NormalizedSnapshotSpanCollection spans)
    {
        if (spans.Count == 0)
            yield break;

        if (spans.Count > 0)
        {
            // look for 'goto' occurrences
            foreach (SnapshotSpan span in _textSearchService.FindAll(new FindData("goto", spans[0].Snapshot, FindOptions.WholeWord | FindOptions.MatchCase, _textStructureNavigator)))
            {
                yield return new TagSpan<GotoTag>(span, new GotoTag());
            }
        }
    }
}


    [Export(typeof(IViewTaggerProvider))]
    [TagType(typeof(TextMarkerTag))]
    [ContentType("code")] // only for code portion. Could be changed to csharp to colorize only C# code for example
    internal class GotoTaggerProvider : IViewTaggerProvider
    {
        [Import]
        internal ITextSearchService TextSearchService { get; set; }

        [Import]
        internal ITextStructureNavigatorSelectorService TextStructureNavigatorSelector { get; set; }

        public ITagger<T> CreateTagger<T>(ITextView textView, ITextBuffer buffer) where T : ITag
        {
            if (textView.TextBuffer != buffer)
                return null;

            return new GotoTagger(TextSearchService, TextStructureNavigatorSelector.GetTextStructureNavigator(buffer)) as ITagger<T>;
        }
    }

    internal class GotoTag : TextMarkerTag
    {
        public GotoTag() : base("goto") { }
    }

    [Export(typeof(EditorFormatDefinition))]
    [Name("goto")]
    [UserVisible(true)]
    internal class GotoFormatDefinition : MarkerFormatDefinition
    {
        public GotoFormatDefinition()
        {
            BackgroundColor = Colors.Red;
            ForegroundColor = Colors.White;
            DisplayName = "Goto Word";
            ZOrder = 5;
        }
    }
