我想获取与使用 NRefactory 的方法相关联的 xml 文档。我使用在此答案中找到的以下代码弄湿了我的脚 

var parser = new CSharpParser();
SyntaxTree tree = parser.Parse(code, "test.cs");

CSharpUnresolvedFile file = tree.ToTypeSystem();
foreach (IUnresolvedTypeDefinition type in file.TopLevelTypeDefinitions) {
    foreach (IUnresolvedMethod method in type.Methods) {
        Console.WriteLine(method.Name);
    }
}

但是，我正在查看 IUnresolvedTypeDefinition 接口，它没有任何“评论”属性。此外，IUnresolvedMethod 接口没有任何“评论”属性。我确实知道可以检索评论，因为我是通过使用与此处找到的 CodeProject 文章相关联的 WinForms 应用程序来检索评论的

演示的作者没有使用“ToTypeSystem()”方法。相反，他遍历树。以下是他所做的一些片段：

SyntaxTree tree = parser.Parse(line, "demo.cs");

                    foreach (var element in tree.Children)
                    {
                        MakeTreeNode(element);
                    }


static void MakeTreeNode(AstNode node)
    {
        Console.WriteLine(GetNodeTitle(node));
        foreach (AstNode child in node.Children)
        {
            MakeTreeNode(child);
        }
    }

    static string GetNodeTitle(AstNode node)
    {
        StringBuilder b = new StringBuilder();
        b.Append(node.Role.ToString());
        b.Append(": ");
        b.Append(node.GetType().Name);
        bool hasProperties = false;
        foreach (PropertyInfo p in node.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
        {
            if (p.Name == "NodeType" || p.Name == "IsNull" || p.Name == "IsFrozen" || p.Name == "HasChildren")
                continue;
            if (p.PropertyType == typeof(string) || p.PropertyType.IsEnum || p.PropertyType == typeof(bool))
            {
                if (!hasProperties)
                {
                    hasProperties = true;
                    b.Append(" (");
                }
                else
                {
                    b.Append(", ");
                }
                b.Append(p.Name);
                b.Append(" = ");
                try
                {
                    object val = p.GetValue(node, null);
                    b.Append(val != null ? val.ToString() : "**null**");
                }
                catch (TargetInvocationException ex)
                {
                    b.Append("**" + ex.InnerException.GetType().Name + "**");
                }
            }
        }
        if (hasProperties)
            b.Append(")");
        return b.ToString() + "\n";
    }

我想知道 NRefactory API 中是否有一种方法可以获取与 C# 代码中的方法相关联的文档。

我确实找到了一种方法，它可以让我获得与 NRefactory API 中的方法相关联的文档。它是具有两个重载的“GetDocumentation”方法

  • DocumentationComment GetDocumentation（IEntity 实体）；
  • DocumentationComment GetDocumentation(IUnresolvedEntity entity, IEntity resolvedEntity);

下面是一个使用示例

                SyntaxTree tree = parser.Parse(line, "demo.cs");

                var testClass = tree.Descendants.OfType<TypeDeclaration>().Single(x => x.Members == Method);
                var testClassAttributes = testClass.Attributes.SelectMany(x => x.Attributes).ToArray();

                List<Dictionary<string, object>> myList = new List<Dictionary<string, object>>();

                string nombreControlador = null;
                string rutaControlador = null;
                string actionKeyPath = null;
                string fullControllerPath = null;
                int counter = 0;

                CSharpUnresolvedFile file = tree.ToTypeSystem();



                foreach (IUnresolvedTypeDefinition type in file.TopLevelTypeDefinitions)
                {
                    nombreControlador = type.Name;
                    actionKeyPath = type.Fields.Skip(1).FirstOrDefault().ConstantValue.ToString();
                    fullControllerPath = type.Fields.First().ConstantValue.ToString();
                    rutaControlador = type.FullName;
                    foreach (IUnresolvedMethod method in type.Methods)
                    {
                        string documentation = file.GetDocumentation(method).Trim();

                        XDocument doc = XDocument.Parse("<documentation>" + documentation + "</documentation>");        
                        Dictionary<string, object> myDic = new Dictionary<string, object>();
                        Console.WriteLine(method.Name);
                        myDic.Add("MethodSignature", method.Name);
                        myDic.Add("MethodDescription", doc.Descendants().Select(e => (string)e.Element("summary")).FirstOrDefault());
                        myDic.Add("ActionKeyPath", actionKeyPath == null? "" : actionKeyPath);
                        myDic.Add("Counter", ++counter);
                        myDic.Add("FullControllerPath", fullControllerPath == null? "" : fullControllerPath);
                        myDic.Add("Route", method.Attributes == null ? "" : method.Attributes.Count <= 1 || method.Attributes.Skip(1) == null? "" : method.Attributes.SelectMany(a => a.);
                        myDic.Add("Verb", "");
                        myDic.Add("Input", "");
                        myDic.Add("Output", "");
                        myList.Add(myDic);
                    }
                }

顺便说一句，我正在使用 5.0 版本的 NRefactorize。我记得在某处读到 5.0 版在抽象语法树中包含注释
