Properties

ContainsAnnotations	Determines whether this node or any sub node, token or trivia has annotations.
ContainsDiagnostics	Determines whether this node or any of its descendant nodes, tokens or trivia have any diagnostics on them.
ContainsDirectives	Determines whether this node has any descendant preprocessor directives.
ContainsSkippedText	Determines whether this node has any descendant skipped text.
FullSpan	The absolute span of this node in characters, including its leading and trailing trivia.
HasLeadingTrivia	Determines whether this node has any leading trivia.
HasStructuredTrivia	Determines whether a descendant trivia of this node is structured.
HasTrailingTrivia	Determines whether this node has any trailing trivia.
IsMissing	Determines whether the node represents a language construct that was actually parsed from the source code. Missing nodes are generated by the parser in error scenarios to represent constructs that should have been present in the source code in order to compile successfully but were actually missing.
IsStructuredTrivia	Determines whether this node represents a structured trivia.
KindText
Language	The language name that this node is syntax of.
Parent	The node that contains this node in its ChildNodes() collection.
ParentTrivia
RawKind	An integer representing the language specific kind of this node.
Span	The absolute span of this node in characters, not including its leading and trailing trivia.
SpanStart	Same as accessing Start on Span.
SyntaxTree	Returns SyntaxTree that owns the node.
SyntaxTreeCore	Returns SyntaxTree that owns the node. If the node does not belong to a tree then one will be generated.

IsIncrementallyIdenticalTo(SyntaxNode)	Returns true if these two nodes are considered "incrementally identical". An incrementally identical node occurs when a SyntaxTree is incrementally parsed using WithChangedText(SourceText) and the incremental parser is able to take the node from the original tree and use it in its entirety in the new tree. In this case, the ToFullString() of each node will be the same, though they could have different parents, and may occur at different positions in their respective trees. If two nodes are incrementally identical, all children of each node will be incrementally identical as well.
