检查字符串是否在C#中以编程方式包含有效的C#代码

using Microsoft.CSharp;
using System;
using System.CodeDom.Compiler;

public class Program
{
    public static void Main()
    {
        string code = "Console.WriteLine(\"Hello, World!\");";
        
        CSharpCodeProvider provider = new CSharpCodeProvider();
        CompilerParameters parameters = new CompilerParameters();
        parameters.GenerateInMemory = true;
        
        CompilerResults results = provider.CompileAssemblyFromSource(parameters, code);
        
        if (results.Errors.HasErrors)
        {
            Console.WriteLine("Invalid C# code");
        }
        else
        {
            Console.WriteLine("Valid C# code");
        }
    }
}

        SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);
        var diagnostics = syntaxTree.GetDiagnostics();
        
        if (diagnostics.Any(d => d.Severity == DiagnosticSeverity.Error))
        {
