ITextStructureNavigator.GetSpanOfNextSibling Method (SnapshotSpan)
Gets the span of the next sibling syntactic element of the specified snapshot span.
Assembly: Microsoft.VisualStudio.Text.Logic (in Microsoft.VisualStudio.Text.Logic.dll)
If the snapshot span has zero length, then the behavior is the same as that of GetSpanOfEnclosing.
If the given active span covers multiple syntactic elements, then this method returns the span of the next sibling element.
If the specified snapshot span covers a syntactic element that does not have a sibling element, then the behavior is the same as that of GetSpanOfEnclosing.
