An immutable text snapshot that represents a state of an IProjectionBuffer. This snapshot contains projections of other text snapshots, described by a list of tracking spans from those buffers. Every modification of a projection buffer or one of its source buffers generates a new projection snapshot.

Remarks
This snapshot contains projections of other text snapshots, described by a list of tracking spans from those buffers. Every modification of a projection buffer or one of its source buffers generates a new projection snapshot.
Properties
| ContentType |
The IContentType of the TextBuffer when this snapshot was current. (Inherited from ITextSnapshot) |
| Item[Int32] |
Gets a single character at the specified position. (Inherited from ITextSnapshot) |
| Length |
Gets the number of UTF-16 characters contained in the snapshot. (Inherited from ITextSnapshot) |
| LineCount |
Gets the positive number of lines in the snapshot. A snapshot whose Length is zero is considered to have one line. (Inherited from ITextSnapshot) |
| Lines |
An enumerator for the set of lines in the snapshot. (Inherited from ITextSnapshot) |
| SourceSnapshots |
Gets the set of one or more text snapshots that contribute source spans to this projection snapshot. The ordering of the list is arbitrary. It does not contain duplicates. |
| SpanCount |
Gets the number of source spans in the projection snapshot. |
| TextBuffer |
Gets the IProjectionBufferBase of which this is a snapshot. |
| Version |
The version of the ITextBuffer that this ITextSnapshot represents. (Inherited from ITextSnapshot) |
Methods
| CopyTo(Int32, Char[], Int32, Int32) |
Copies a range of text to a character array. (Inherited from ITextSnapshot) |
| CreateTrackingPoint(Int32, PointTrackingMode, TrackingFidelityMode) |
Creates a ITrackingPoint against this snapshot. (Inherited from ITextSnapshot) |
| CreateTrackingPoint(Int32, PointTrackingMode) |
Creates a ITrackingPoint against this snapshot. (Inherited from ITextSnapshot) |
| CreateTrackingSpan(Int32, Int32, SpanTrackingMode, TrackingFidelityMode) |
Creates a ITrackingSpan against this snapshot. (Inherited from ITextSnapshot) |
| CreateTrackingSpan(Int32, Int32, SpanTrackingMode) |
Creates a ITrackingSpan against this snapshot. (Inherited from ITextSnapshot) |
| CreateTrackingSpan(Span, SpanTrackingMode, TrackingFidelityMode) |
Creates a ITrackingSpan against this snapshot. (Inherited from ITextSnapshot) |
| CreateTrackingSpan(Span, SpanTrackingMode) |
Creates a ITrackingSpan against this snapshot. (Inherited from ITextSnapshot) |
| GetLineFromLineNumber(Int32) |
Gets an ITextSnapshotLine for the given line number. (Inherited from ITextSnapshot) |
| GetLineFromPosition(Int32) |
Gets an ITextSnapshotLine for a line at the given position. (Inherited from ITextSnapshot) |
| GetLineNumberFromPosition(Int32) |
Gets the number of the line that contains the character at the specified position. (Inherited from ITextSnapshot) |
| GetMatchingSnapshot(ITextBuffer) |
Gets the snapshot of the specified text buffer that corresponds to this snapshot. |
| GetSourceSpans() |
Gets all the source spans for the projection snapshot. |
| GetSourceSpans(Int32, Int32) |
Gets a read-only collection of source snapshot spans starting at the specified span index.
The |
| GetText() |
Gets all the text in the snapshot. (Inherited from ITextSnapshot) |
| GetText(Int32, Int32) |
Gets text from the snapshot starting at |
| GetText(Span) |
Gets text from the snapshot starting at the beginning of the span and having length equal to the length of the span. (Inherited from ITextSnapshot) |
| MapFromSourceSnapshot(SnapshotPoint, PositionAffinity) |
Maps from a snapshot point in one of the source snapshots to the corresponding position in the projection snapshot. |
| MapFromSourceSnapshot(SnapshotSpan) |
Maps a snapshot span of a source buffer to a list of spans of the projection snapshot. The resulting ordered list may be empty, contain a single element, or contain multiple elements. |
| MapToSourceSnapshot(Int32, PositionAffinity) |
Maps a position in the projection snapshot to the corresponding position in a source snapshot. |
| MapToSourceSnapshot(Int32) |
Maps a position in the projection snapshot to the corresponding position in a source snapshot. If the mapping is ambiguous (occurs on a source span seam), see GetTypicalInsertionPosition(SnapshotPoint, ReadOnlyCollection<SnapshotPoint>) to choose a source buffer. |
| MapToSourceSnapshots(Int32) |
Maps a position in the projection snapshot to the corresponding position in one or more source snapshots. |
| MapToSourceSnapshots(Span) |
Maps a span of the current projection snapshot to a list of snapshot spans belonging to source snapshots. The resulting spans will be ordered by the order of their appearance in the projection. |
| ToCharArray(Int32, Int32) |
Converts a range of text to a character array. (Inherited from ITextSnapshot) |
| Write(TextWriter, Span) |
Writes a substring of the contents of the snapshot. (Inherited from ITextSnapshot) |
| Write(TextWriter) |
Writes the contents of the snapshot. (Inherited from ITextSnapshot) |
