我试图使用 SubSonic 2.1、MySQL 和 C# 进行TDD，当我开始使用下面的代码测试更新现有记录时，

public void Test2()
{
    User.Insert("jmarcus1", "jmarcus1", "jackass", "marcus", 3, false);
    User users = new User();
    int ulevel = 1;
    User.Update(2, "jmarcus1", "jmarcus1", "jackass", "marcus", ulevel, false);
    Assert.AreEqual(1, users.Ulevel);
}

与以下

在我看来，您的参数不正常。PK 应该是第一件事——你确定他们排对了吗？

你在使用 ActiveRecord 吗？如果是这样-您是否尝试过：

User u=new User();
u.UserName("jmarcus1");
u.Name="jackass"
u.Ulevel=1;
...
u.Save();

User u=new User("jmarcus1");
u.UILevel=2;
u.Save();

显然，解决方案是，按照 Rob 上面的出色建议，

User u = User.FetchByID(2);
u.Ulevel = ulevel;
u.save();

在您指定要更新的记录之前，我不太确定上面的代码段是否适用于更新。

然而，我对 Rob 的问题是，为什么 "u.Update(2, "jmarcus",..." 会出现上述错误？
