A mutable sequence of Unicode characters encoded using UTF-16. Positions within the buffer are treated as a sequence of characters (starting at character zero) or as a sequence of lines (starting at line zero). An empty buffer has a single line containing no characters.

Positions in this buffer are treated as a sequence of characters (starting at character zero), or as a sequence of lines (starting at line zero). An empty buffer has a single line containing no characters.
Properties
ContentType |
Gets the content type of the text in the buffer. |
CurrentSnapshot |
Gets the current content of the buffer. |
EditInProgress |
Determines whether an edit operation is currently in progress on the ITextBuffer. |
Properties |
The collection of properties controlled by the property owner. (Inherited from IPropertyOwner) |
Methods
ChangeContentType(IContentType, Object) |
Changes the IContentType for this ITextBuffer. |
CheckEditAccess() |
Determines whether edit operations on this text buffer are permitted on the calling thread. If TakeThreadOwnership() has previously been called, edit operations are permitted only from the same thread that made that call. |
CreateEdit() |
Creates an ITextEdit object that handles compound edit operations on this buffer. |
CreateEdit(EditOptions, Nullable<Int32>, Object) |
Creates an ITextEdit object that handles compound edit operations on this buffer. |
CreateReadOnlyRegionEdit() |
Creates an IReadOnlyRegionEdit object that handles adding or removing read-only regions from this buffer. |
Delete(Span) |
Deletes a sequence of characters from the buffer. |
GetReadOnlyExtents(Span) |
Gets a list of read-only regions that overlap the given span. |
Insert(Int32, String) |
Inserts the given |
IsReadOnly(Int32) |
Determines whether a text insertion would be prohibited at |
IsReadOnly(Int32, Boolean) |
Determines whether a text insertion would be prohibited at |
IsReadOnly(Span) |
Determines whether a text modification or deletion would be prohibited at |
IsReadOnly(Span, Boolean) |
Determines whether a text modification or deletion would be prohibited at |
Replace(Span, String) |
Replaces a sequence of characters with different text. This is equivalent to first deleting the text to be replaced and then inserting the new text. |
TakeThreadOwnership() |
Claims ownership of this buffer for the current thread. All subsequent modifications of this ITextBuffer must be made from the current thread, or else an InvalidOperationException will be raised. |
Events
Changed |
Occurs when a non-empty ITextEdit is successfully applied. |
ChangedHighPriority |
Occurs when a non-empty ITextEdit is successfully applied. |
ChangedLowPriority |
Occurs when a non-empty ITextEdit is successfully applied. |
Changing |
Occurs just before a non-empty ITextEdit is applied. |
ContentTypeChanged |
Occurs whenever the IContentType has been changed. |
PostChanged |
Occurs after the Changed event and any resulting edits. |
ReadOnlyRegionsChanged |
Occurs when an IReadOnlyRegionEdit has created or removed read-only regions. |
