Properties

Delta	The effect On the length of the buffer resulting from this change. (Inherited from ITextChange)
IsOpaque	Indicates whether the change is opaque. Opaque changes are always replacements in which both the old text and new text are non-empty. The differ from other changes in the manner in which ITrackingPoints and ITrackingSpans behave. When tracking across an opaque replacement, a point or span endpoint that lies within the deleted text will keep the same offset within the inserted text (normally a point would move either to the beginning or end of the inserted text, depending on its tracking mode). (Inherited from ITextChange2)
LineCountDelta	The effect of this change on the number of lines in the snapshot. (Inherited from ITextChange)
NewEnd	The end position of the NewText in the snapshot immediately after the text change. (Inherited from ITextChange)
NewLength	The length of NewText. (Inherited from ITextChange)
NewPosition	The position of the text change in the snapshot immediately after the change. The position can differ from OldPosition only when there is more than one ITextChange included in moving from one snapshot to the next. (Inherited from ITextChange)
NewSpan	The span of the ITextChange in the snapshot immediately after the change. (Inherited from ITextChange)
NewText	The text that replaced the old text. (Inherited from ITextChange)
OldEnd	The end position of the OldText in the snapshot immediately before the change. (Inherited from ITextChange)
OldLength	The length of OldText. (Inherited from ITextChange)
OldPosition	The position of the text change in the snapshot immediately before the change. The position can differ from NewPosition only when there is more than one ITextChange included in moving from one snapshot to the next. (Inherited from ITextChange)
OldSpan	The span of the text change in the snapshot immediately before the change. (Inherited from ITextChange)
OldText	The text that was replaced. (Inherited from ITextChange)

Methods

GetNewText(Span)	The text that replaced the old text, starting at the beginning of the span and having length equal to the length of the span.
GetNewTextAt(Int32)	Gets a character at given position of the text that replaced the old text.
GetOldText(Span)	Gets the text that was replaced, starting at the beginning of the span and having length equal to the length of the span.
GetOldTextAt(Int32)	Gets a character at given position of the text that was replaced.
