C# 中的遞歸 function 中的問題

Question

我的遞歸 function 是

private dynamic FillRecursive(List<AllAccounts> flatObjects, Guid accountID)
{
    List<AllAccounts> recursiveObjects = new List<AllAccounts>();

    foreach (var item in flatObjects.Where(x => x.ParentID.Equals(accountID)))
    {
        recursiveObjects.Add(new AllAccounts
            {
                AccountID = item.AccountID ,                
                Children = FillRecursive(flatObjects, item.AccountID)
            });
    }

    return recursiveObjects;
}

當我從 postman 向此 function 發送請求時，它會停止 Visual Studio Code 中正在運行的程序。 請幫我解決這個問題。 謝謝

測試這是否有效

private dynamic FillRecursive(List<AllAccounts> flatObjects, Guid accountID,  List<AllAccounts> recursiveObjects=null)
{
    if(recursiveObjects==null)
       recursiveObjects = new List<AllAccounts>();

    foreach (var item in flatObjects.Where(x => x.ParentID.Equals(accountID)))
    {
        recursiveObjects.Add(new AllAccounts
            {
                AccountID = item.AccountID ,                
                Children = FillRecursive(flatObjects, item.AccountID,recursiveObjects)
            });
    }

    return recursiveObjects;
}
