public class CommonMenuEditor : EditorWindow

    [InitializeOnLoadMethod]
    static void Start()
    {
        PrefabUtility.prefabInstanceUpdated += OnRemove;
    }
    static public void OnRemove(GameObject obj)
    {
        Remove();
    }

    // 预制件鼠标右键移除

    {
        GameObject source = PrefabUtility.GetPrefabParent(Selection.activeGameObject) as GameObject;
        if (source == null) return;
        string prefabPath = AssetDatabase.GetAssetPath(source).ToLower();

        if (prefabPath.EndsWith(".prefab") == false) return;

        var items = Selection.activeGameObject.GetComponentsInChildren<Shadow>();
        if (items.Length == 0)
        {

            GameObject.DestroyImmediate(item, true);
        }

        GameObject go = Selection.activeGameObject;
        PrefabUtility.ReplacePrefab(Selection.activeGameObject, source, ReplacePrefabOptions.ConnectToPrefab | ReplacePrefabOptions.ReplaceNameBased);
        EditorApplication.delayCall = delegate
        {
            Selection.activeGameObject = go;
        };
        AssetDatabase.SaveAssets();
