示例1: GetDeclarationExpression
private static DeclarationExpressionSyntax GetDeclarationExpression(
SourceText sourceText, IdentifierNameSyntax identifier,
TypeSyntax newType, VariableDeclaratorSyntax declaratorOpt)
{
newType = newType.WithoutTrivia().WithAdditionalAnnotations(Formatter.Annotation);
var designation = SyntaxFactory.SingleVariableDesignation(identifier.Identifier);
if (declaratorOpt != null)
{
// We're removing a single declarator. Copy any comments it has to the out-var.
//
// Note: this is tricky due to comment ownership. We want hte comments that logically
// belong to the declarator, even if our syntax model attaches them to other tokens.
var precedingTrivia = declaratorOpt.GetAllPrecedingTriviaToPreviousToken(
sourceText, includePreviousTokenTrailingTriviaOnlyIfOnSameLine: true);
if (precedingTrivia.Any(t => t.IsSingleOrMultiLineComment()))
{
designation = designation.WithPrependedLeadingTrivia(MassageTrivia(precedingTrivia));
}
if (declaratorOpt.GetTrailingTrivia().Any(t => t.IsSingleOrMultiLineComment()))
{
designation = designation.WithAppendedTrailingTrivia(MassageTrivia(declaratorOpt.GetTrailingTrivia()));
}
}
return SyntaxFactory.DeclarationExpression(newType, designation);
