Class 不包含在显示窗体时接受0个参数的构造函数
我有一个rpg游戏，我已经工作了一段时间，我似乎无法得到列表设置。对于我想使用的不同设备，我有不同的课程，我发现很难在这些课程中设置列表，然后从不同的课程调用它，并以我的形式调用组合框。所以我决定从头开始，可能会问一个问题，所以我删除了所有的列表，并尝试运行该程序。出于某种原因，在我的“创建角色”屏幕上，我调用了Class 不包含在显示窗体时接受0个参数的构造函数,class,Class,我有一个rpg游戏，我已经工作了一段时间，我似乎无法得到列表设置。对于我想使用的不同设备，我有不同的课程，我发现很难在这些课程中设置列表，然后从不同的课程调用它，并以我的形式调用组合框。所以我决定从头开始，可能会问一个问题，所以我删除了所有的列表，并尝试运行该程序。出于某种原因，在我的“创建角色”屏幕上，我调用了 this.Hide(); HomeScreen next = new HomeScreen(); next.ShowDialog(); 但是对于我的主屏幕表单，我最终在那里放置了一个

无法向windows窗体的构造函数添加参数。这非常烦人，但这是平台的一个限制。在构建类之后，您必须修改它。如果需要严格的状态控制，您可以始终围绕表单构建一个包装类。即使我从构造函数中取出参数，它也会返回一个“System.NullReferenceException”，这是在创建屏幕窗口尝试切换到主屏幕后发生的。我相信在删除参数并保留全局KyleRpgGame父项之后；它使我所有的变量无效。我试图将一个类包装在form类周围，但这也不起作用。My labels and InitializeComponent（）；下面有红色的波浪。
