.net core 并不是所有的调用表达式都被重写

我想重写SyntaxTree中“MyMethod”的所有调用表达式，以添加一个具有0的文本参数

private class Rewriter : CSharpSyntaxRewriter
    {
        public int Id { get; set; }
        public override SyntaxNode VisitInvocationExpression(InvocationExpressionSyntax node)
        {
            var invokName = node.Expression.ToString();
            if (invokName == "MyMethod")
            {
                var argus = node.ArgumentList.AddArguments(
SyntaxFactory.Argument(SyntaxFactory.LiteralExpression(SyntaxKind.NumericLiteralExpression, SyntaxFactory.Literal(Id))));
                return node.Update((ExpressionSyntax)Visit(node.Expression), argus);
            }
            return node;
        }
    }
    static void Main(string[] args)
    {
        SyntaxTree oriTree = CSharpSyntaxTree.ParseText(@"
        public class MyClass
        {
            public string MyMethod(int id)
            {
                return $""{id}"";
            }
            public void Say()
            {
                var tmp = MyMethod();//worked
                var tmp1 = MyMethod();//worked
                var tmp2 = ""Hi "" + MyMethod();//worked
                Console.WriteLine($""Say {MyMethod()}"");//Not worked
                Console.WriteLine(""Hello "" + MyMethod());//Not worked                    
            }
        }");
        var syntaxRoot = oriTree.GetCompilationUnitRoot();
        var visitor = new Rewriter();
        visitor.Id = 0;
        var changedSyntaxTree = visitor.Visit(syntaxRoot).SyntaxTree;
    }

但并非所有内容都被改写

与

var methods=syntaxRoot.genderantnodes（）.OfType（）。其中（o=>o.Expression.ToString（）==“MyMethod”）；

我可以枚举“MyMethod”的所有调用表达式。但我不知道如何在没有CSharpSyntaxRewriter的情况下更改语法树

我怎么做？谢谢。

根据CyrusNajmabadi的

您需要这样做：

谢谢CyrusNajmabadi

var methods = syntaxRoot.DescendantNodes().OfType<InvocationExpressionSyntax>().Where(o => o.Expression.ToString() == "MyMethod");

      public override SyntaxNode VisitInvocationExpression(InvocationExpressionSyntax node)
        {
            node = (InvocationExpressionSyntax)base.VisitInvocationExpression(node);
            // now, the rest of your code:
            var invokName = node.Expression.ToString();
            // etc.
