如何通过roslyn检查两个方法是否匹配签名？

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;

public class MethodSignatureChecker
{
    public bool CheckMethodSignature(string method1, string method2)
    {
        SyntaxTree tree1 = CSharpSyntaxTree.ParseText(method1);
        SyntaxTree tree2 = CSharpSyntaxTree.ParseText(method2);

        var root1 = (CompilationUnitSyntax)tree1.GetRoot();
        var root2 = (CompilationUnitSyntax)tree2.GetRoot();

        var methodDeclaration1 = root1.DescendantNodes().OfType<MethodDeclarationSyntax>().FirstOrDefault();
        var methodDeclaration2 = root2.DescendantNodes().OfType<MethodDeclarationSyntax>().FirstOrDefault();

        if (methodDeclaration1 == null || methodDeclaration2 == null)
        {
            return false;
        }

        return methodDeclaration1.Identifier.ValueText == methodDeclaration2.Identifier.ValueText &&
               methodDeclaration1.ParameterList.ToString() == methodDeclaration2.ParameterList.ToString();
    }
}
