I find the solution

using UnityEditor;
using UnityEngine;

namespace Ro.Unity
{
    public class TestOpenFile
    {
        [MenuItem("Test/Open File")]
        public static void St()
        {
            var asset = AssetDatabase.LoadMainAssetAtPath("Assets/Editor/Test/TestOpenFile.cs");
            Debug.Log($"asset:{asset}");
            Selection.activeObject = asset;
        }
    }
}
