【问题描述】:
有谁知道我可以在哪里找到基于 Roslyn 诊断的令牌着色的“简单”示例。是的,我可以将它们设为信息、警告、错误或隐藏。因此,假设要使用隐藏,因此它不会出现在错误列表/窗口中,但可以访问,以便我稍后可以使用它。
现在我有了这些隐藏的诊断信息,现在我想影响 IDE 中文本的着色。
这就是我尝试过的。
Private Sub CreateVisuals(ByVal line As ITextViewLine)
Try
'grab a reference to the lines in the current TextView
Dim textViewLines = _view?.TextViewLines
If textViewLines Is Nothing Then Exit Sub
If line Is Nothing Then Exit Sub
Dim lineStart As Integer = line.Start
Dim lineEnd As Integer = line.End
Dim q = textViewLines.FirstOrDefault
If q Is Nothing Then Exit Sub
Dim qq = q.Snapshot.GetOpenDocumentInCurrentContextWithChanges
If qq Is Nothing Then Exit Sub
Dim sm = qq.GetSemanticModelAsync.Result '..GetSemanticModelAsync.Result
' Dim di = sm.GetSyntaxDiagnostics.ToArray
If sm Is Nothing Then Exit Sub
Dim diags = sm.GetDiagnostics.ToArray
我试过GetSyntaxDiagnostic
If diags.Any() = False Then Exit Sub
For Each d In diags
' This is the ID if the Diagnostic I want to color.
'If d.Id<>"SFD000" Then Continue For
Dim charSpan As New SnapshotSpan(_view.TextSnapshot,
Span.FromBounds(d.Location.SourceSpan.Start, d.Location.SourceSpan.End))
Dim g As Geometry = textViewLines.GetMarkerGeometry(charSpan)
If g IsNot Nothing Then
Dim drawing As New GeometryDrawing(_brush, _pen, g) : drawing.Freeze()
Dim drawingImage As New DrawingImage(drawing) : drawingImage.Freeze()
Dim image As New Image()
image.Source = drawingImage
'Align the image with the top of the bounds of the text geometry
Canvas.SetLeft(image, g.Bounds.Left)
Canvas.SetTop(image, g.Bounds.Top)
_layer?.AddAdornment(AdornmentPositioningBehavior.TextRelative,
charSpan, Nothing, image, Nothing)
End If
Next
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
我得到了编译器的诊断问题,但不是我的。为什么?
示例可以是 C# 或 VB.net。
