示例1: Initialize
private async Task<Document> Initialize(Document document, FieldDeclarationSyntax localDeclaration,
CancellationToken cancellationToken)
{
var tree = await document.GetSyntaxTreeAsync(cancellationToken);
var root = tree.GetRoot(cancellationToken);
var constructors = root.DescendantNodes().OfType<ConstructorDeclarationSyntax>().ToList();
var csor = constructors.FirstOrDefault();
SyntaxNode visitingRoot = root;
if (csor == null)
{
var oldClass = localDeclaration.FirstAncestorOrSelf<ClassDeclarationSyntax>();
var className = oldClass.Identifier.ToString();
var paramList = RoslynExtensions.GenerateParameters(new[] { localDeclaration.Declaration.Type });
var newCtor = SyntaxFactory.ConstructorDeclaration(
attributeLists: SyntaxFactory.List(new AttributeListSyntax[] { }),
modifiers: SyntaxFactory.TokenList(SyntaxFactory.Token(SyntaxKind.PublicKeyword)),
identifier: oldClass.Identifier,
parameterList: paramList,
