c# - 为什么此 C# 构造函数会产生不一致的可访问性错误？

Question

我遇到可访问性错误

Inconsistent accessibility: parameter type 'FoolballLeague.FootballLeagueDatabase' is less accessible than method 'FoolballLeague.MainMenu.MainMenu(FoolballLeague.FootballLeagueDatabase)'
C:\Users\achini\Desktop\FootballLeague\FootballLeague\MainMenu.cs
//public MainMenu(FootballLeagueDatabase footballLeagueDatabaseIn) //{ //InitializeComponent(); //footballLeagueDatabase = footballLeagueDatabaseIn; //}

当我运行这段代码时

public partial class MainMenu : Form
{
    FootballLeagueDatabase footballLeagueDatabase;
    Game game;
    Login login;

    public MainMenu()
    {
        InitializeComponent();
        changePanel(1);
    }

    public MainMenu(FootballLeagueDatabase footballLeagueDatabaseIn)
    {
        InitializeComponent();
        footballLeagueDatabase = footballLeagueDatabaseIn;
    }
}

我也不知道为什么。我错过了什么？可访问性是什么意思？

Answer 1

在声明 FootballLeagueDatabase 的地方将其定义公开，这应该会有所帮助。
