我正在尝试序列化帐户向量，但我不断收到以下异常：-

要实现 XML 可序列化，从 ICollection 继承的类型必须在其继承层次结构的所有级别上都有 Add(Account) 的实现。cliext.vector 没有实现 Add(Account)。

我在课堂上添加了一个 Add(Account) 函数，但它仍然不起作用。我对 C++ 比较陌生，所以我的代码可能很差，或者可能不是做我想做的事情的正确方法。

所有帮助表示赞赏。

这是主要功能：-

// TestDotNetXML.cpp : main project file.

#include "stdafx.h"

using namespace System;
using namespace System::Xml;
using namespace System::Xml::Serialization;

int main(array<System::String ^> ^args)
{
    AccountList^ MyAccountList = gcnew AccountList;
    Account^ Account1 = gcnew Account("1","1","1","1");    
    Account^ Account2 = gcnew Account("2","2","2","2");
    Account Account3;

    Account3.setAccountName("3");
    Account3.setUserName("3");
    Account3.setPassword("3");
    Account3.setDescription("3");

    MyAccountList->Add(Account1);
    MyAccountList->Add(Account2);
    MyAccountList->Add(Account3);


    try
    {
        XmlSerializer^ x = gcnew XmlSerializer(MyAccountList->GetType());
        x->Serialize(Console::Out, MyAccountList);
    }
    catch(System::InvalidOperationException^ ex)
    {
        Console::WriteLine(ex->InnerException);
    }

    Console::WriteLine();
    Console::ReadLine();

    return 0;
}
