为最近的项目和解决方案 Visual Studio 增加价值

Question

我正在尝试将扩展创建的项目添加到最近的项目和解决方案命令中。我能够通过这段代码获得命令列表

var mruPath = @"MRUItems\{a9c4a31f-f9cb-47a9-abc0-49ce82d0b3ac}\Items";
String exeName = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileVersionInfo.FileName;

using (ExternalSettingsManager ext = ExternalSettingsManager.CreateForApplication(exeName))
{
    WritableSettingsStore store = ext.GetWritableSettingsStore(SettingsScope.UserSettings);
    var mruList = new ArrayList();

    string solPath = dte.Solution.FullName;
    string solName = solPath.Split('\\').Last();
    solName = solName.Split('.').First();

    string newPath = newsolPath + @"|{00000000-0000-0000-0000-000000000000}|False|" + solName + @"||||{00000000-0000-0000-0000-000000000000}";
    store.SetString(mruPath, "0", newPath);
    names = store.GetPropertyNames(mruPath);

    foreach (string name in names)
    {
        string value = store.GetString(mruPath, name);
        string[] subValue = value.Split('|');
        mruList.Add(subValue[0]);
    }
}

我正在尝试将 newPath 添加到列表中，但它没有添加，我不明白为什么。有人可以帮我解决这个问题吗？
