Public method SnapshotSpan(SnapshotPoint, SnapshotPoint) Initializes a new instance of a SnapshotSpan from two SnapshotPoint objects.
Public method SnapshotSpan(SnapshotPoint, Int32) Initializes a new instance of a SnapshotSpan from an existing SnapshotPoint and a specified length.
Public method SnapshotSpan(ITextSnapshot, Int32, Int32) Initializes a new instance of a SnapshotSpan with the specified snapshot, start point, and length.
