示例1: TryGetTextForSymbol

        private bool TryGetTextForSymbol(SyntaxToken token, SemanticModel semanticModel, Document document, CancellationToken cancellationToken, out string text)
        {
            ISymbol symbol;
            if (token.Parent is TypeArgumentListSyntax)
            {
                var genericName = token.GetAncestor<GenericNameSyntax>();
                symbol = semanticModel.GetSymbolInfo(genericName, cancellationToken).Symbol ?? semanticModel.GetTypeInfo(genericName, cancellationToken).Type;
            }
            else if (token.Parent is NullableTypeSyntax && token.IsKind(SyntaxKind.QuestionToken))
            {
                text = "System.Nullable`1";
                return true;
            }
            else
            {
                symbol = semanticModel.GetSemanticInfo(token, document.Project.Solution.Workspace, cancellationToken)
                                      .GetAnySymbol(includeType: true);

                if (symbol == null)
                {
                    var bindableParent = document.GetLanguageService<ISyntaxFactsService>().GetBindableParent(token);
                    var overloads = semanticModel.GetMemberGroup(bindableParent);
                    symbol = overloads.FirstOrDefault();
                }
            }

            // Local: return the name if it's the declaration, otherwise the type
            if (symbol is ILocalSymbol && !symbol.DeclaringSyntaxReferences.Any(d => d.GetSyntax().DescendantTokens().Contains(token)))
            {
                symbol = ((ILocalSymbol)symbol).Type;
            }

            // Range variable: use the type
            if (symbol is IRangeVariableSymbol)
            {
                var info = semanticModel.GetTypeInfo(token.Parent, cancellationToken);
                symbol = info.Type;
            }

            // Just use syntaxfacts for operators
            if (symbol is IMethodSymbol && ((IMethodSymbol)symbol).MethodKind == MethodKind.BuiltinOperator)
            {
                text = null;
                return false;
            }

            text = symbol != null ? FormatSymbol(symbol) : null;
            return symbol != null;
        }
