Watch window CS0103 - follow up to exclude my code as problem-CodePudding

Problem after updating VS2022 viewing the watches. After an answer with proposal to post the code, I do so to exclude the problem is caused by my code prior to reporting a bug.

The original question:

All projects are 'out-of-the-box'

Library - StrangParser.cs

namespace html
{

    public enum Pin
    {
        Start,
        End,
        Both,

        private int     position    = -1;
        private int     start       = -1;

Form App - Form1.cs - code

using System.Windows.Forms;
using html;

namespace contentdownloader
{

    public partial class Form1 : Form
    {

        string          filecontent     = "<html><head></head><body></body></html>";

        StringParser    watch_parser    = null;
        string          watch_token     = null;

        public Form1()
        {

            InitializeComponent();


            StringParser    parser      = new StringParser();
            watch_parser = parser;

            parser.Content = filecontent;

            string token = "";
            while (!parser.Next('<'))
            {
                
                //parser.Pin(html.Pin.Both);
                parser.Next('>');
                token = watch_token = parser.Token;
                parser.Pin(html.Pin.Both);

            }

        }

    }

}

CodePudding user response：

You can change your code like this, define parser and token before the function InitializeComponent() of Form1:

public partial class Form1 : Form
{
    string filecontent = "<html><head></head><body></body></html>";
    StringParser parser = new StringParser();
    string token = "";
    public Form1()
    {

        InitializeComponent();
        parser.Content = filecontent;
        while (!parser.Next('<'))
        {
            parser.Next('>');
            token = parser.Token;
        }

    }
}

Here is my test result:
