好的，我对收到的错误完全迷失了。我正在教我的课本中的一个例子。

这是我收到的错误:

错误1非静态字段，方法或属性'ClassofEmployees.Form1.managers.BCY.get'需要对象引用C:\ Users \ T-Ali \ Desktop \ SHawnasschool \ vb.net 2 C#\ projects \ ClassofEmployees \ ClassofEmployees \ Form1.cs 59 13 ClassofEmployees

我了解的是该对象未创建。但是我相信我用以下代码创建的对象:

 //create new employee object
        employee newemployee = new employee();
        //get employee data
        getEmployeeData(newemployee);
        //add employee data to new form window list

为什么employee.name或任何employee.something起作用，但是经理部分却不起作用？我怎样才能解决这个问题？

最佳答案

问题是您正在从manager类读取非静态字段。

managers.backgroundCheck = bCYes;
managers.isSalary = salaryYes;
managers.responsibilitys = responsibilitys.Text;

managers是一个类，而不是对象实例。您需要像对待员工一样创建一个新的经理对象。

关于c# - 错误: An object reference is required for the non-static field, method, or property，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17514617/
