我设置了一个包含名称/数字/等的类，并创建了一个保存它们的对象列表。我想在ListView中的第二个窗体上显示它们。现在，我使用的是吸气像...我可以在C＃中将对象列表从一个表单传递给另一个表单吗？
public List<Employee> GetEmpList(){
return EmployeeList;
}
然后在第二个窗体的构造我使用Form1.GetEmpList（）之类......
DisplayForm{
InitializeComponent();
LoadEmployees(EmployeeAddition.GetList());
}
我正在和错误说“非静态字段需要对象引用”。我调用的方法是非静态的，并返回Form1类中List的引用。我甚至试图让List公开并使用Form1.List调用，但它仍然给我同样的错误。
有没有办法在表单类之间传递一个List或是不可能的？
编辑：Poeple说，需要更多的信息。我不想在这里复制粘贴所有的代码，但是我只是因为我是新手而不太清楚什么是相关的，哪些不相关。 （我正在上一堂课，但远程学习，而我的老师是......好远程老师，没用的，她实际上告诉我在这里问）
我想我缺少如何instatize方法，我认为当从该类创建对象时，方法成为对象的一部分。该方法是Form1（重命名，但多数民众赞成是什么）类/对象的一部分。我会在这里愚弄这些代码，我不知道这是否令人不悦。如果是这样，我很抱歉。

在代码中东欧之后，我想我可能会看到你说的话有关从静态类，而不是一个对象调用它。有没有办法找到编译器从第一个Form创建的Object的名称？
它应该是'EmployeeAddition.GetEmpList（）' – sarwar026
