我的控制器没有返回应有的结果

Question

我将尽力提供您需要的一切信息，以帮助我诊断我的问题。数据库记录在 Full_name 字段中包含一个值，但当我运行 GetAll 或 GetById 时，它不会返回。我缺少什么？预先感谢您！

先调试： 我认为您应该首先在这些行之间添加一些日志，

dbObject.Index = abilityScore.Index;
    dbObject.Name = abilityScore.Name;
    dbObject.Full_name = abilityScore.Full_name;
    dbObject.Desc = abilityScore.Desc;
    dbObject.Url = abilityScore.Url;
    //here print dboobject, and abilitScore object
    await _dataContext.SaveChangesAsync();
    return await GetAll();

然后看看什么没有被正确分配，你的 dbObject.full_name 应该是一个空字符串，对吗？但你的abilitScore.full_name不应该。我有一种感觉，你的 _ 给你带来了一些问题。 让我知道发生了什么！
