如何从class中获取它继承的所有接口(使用roslyn)？

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;
using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string code = @"
            using System;

            interface IInterface1 { }
            interface IInterface2 { }

            class MyClass : IInterface1, IInterface2 { }
        ";

        SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);
        CompilationUnitSyntax root = syntaxTree.GetCompilationUnitRoot();

        // 获取class的语法节点
        ClassDeclarationSyntax classDeclaration = root.DescendantNodes().OfType<ClassDeclarationSyntax>().FirstOrDefault();

        // 获取class的符号信息
        SemanticModel semanticModel = GetSemanticModel(syntaxTree);
        ITypeSymbol classSymbol = semanticModel.GetDeclaredSymbol(classDeclaration);

        // 获取class继承的所有接口
        var interfaces = classSymbol.AllInterfaces;

        foreach (var interfaceSymbol in interfaces)
        {
            Console.WriteLine(interfaceSymbol.Name);
        }
    }

    static SemanticModel GetSemanticModel(SyntaxTree syntaxTree)
    {
        MetadataReference[] references = new MetadataReference[]
        {
            MetadataReference.CreateFromFile(typeof(object).Assembly.Location),
            MetadataReference.CreateFromFile(typeof(Console).Assembly.Location),
            // 添加其他需要引用的程序集
        };

        CSharpCompilation compilation = CSharpCompilation.Create("MyCompilation",
            syntaxTrees: new[] { syntaxTree },
            references: references,
            options: new CSharpCompilationOptions(OutputKind.ConsoleApplication));

        return compilation.GetSemanticModel(syntaxTree);
    }
}
