示例1: ApplyDocComment
private SyntaxNode ApplyDocComment(SyntaxNode node, string docCommentId)
{
if (docCommentId == null)
return node;
// Look up the comment text
string docCommentText = GetDocCommentForId(docCommentId);
// Get the SyntaxTrivia for the comment
SyntaxTree newTree = (CSharpSyntaxTree)CSharpSyntaxTree.ParseText(docCommentText);
var newTrivia = newTree.GetRoot().GetLeadingTrivia();
if (node.HasLeadingTrivia)
{
SyntaxTriviaList triviaList = node.GetLeadingTrivia();
// Check to see if there are any existing doc comments
var docComments = triviaList
.Where(n => n.IsKind(SyntaxKind.SingleLineDocumentationCommentTrivia) || n.IsKind(SyntaxKind.MultiLineDocumentationCommentTrivia))
.Select(t => t.GetStructure())
.OfType<DocumentationCommentTriviaSyntax>()
.ToList();
// Append the doc comment (even if the API already has /// comments)
node = node.InsertTriviaBefore(triviaList.First(), newTrivia);
}
else // no leading trivia
{
node = node.WithLeadingTrivia(newTrivia);
}
return node.WithAdditionalAnnotations(Simplifier.Annotation);
}示例2: TraverseAndConvert
public SyntaxNode TraverseAndConvert(SyntaxNode node, SyntaxNode newNode)
{
// Step 1: Handle current node
// Find out if this node is a documentable API declaration
// If not, skip to go to the child nodes.
string docCommentId = GetAPIForNode(node);

// Get the SyntaxTrivia for the comment

// Read a doc comment from a syntax tree.
//var classNode = (ClassDeclarationSyntax)newTree.GetRoot().ChildNodes().First();
//var newTrivia = classNode.GetLeadingTrivia();
//var docCommentTrivia = newTrivia.Single(t => t.Kind() == SyntaxKind.SingleLineDocumentationCommentTrivia ||

// Find out if there is an existing comment or doc comment
