如何使用Roslyn更改属性

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

public class Program
{
    public static void Main()
    {
        // 1. 解析代码
        string code = @"
            using System;

            public class MyClass
            {
                [Obsolete]
                public string MyProperty { get; set; }
            }
        ";
        SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);

        // 2. 遍历语法树
        var root = syntaxTree.GetRoot();
        var attributeNodes = root.DescendantNodes().OfType<AttributeSyntax>();

        // 3. 修改属性
        foreach (var attributeNode in attributeNodes)
        {
            if (attributeNode.Name.ToString() == "Obsolete")
            {
                // 移除Obsolete属性
                var newAttributeLists = attributeNode.Parent.Parent.RemoveNode(attributeNode.Parent, SyntaxRemoveOptions.KeepNoTrivia);
                root = root.ReplaceNode(attributeNode.Parent.Parent, newAttributeLists);
            }
        }

        // 4. 生成修改后的代码
        var newCode = root.GetText().ToString();
        Console.WriteLine(newCode);
    }
}
