推荐答案

将combobox修饰符更改为public，您应该可以通过以下方式访问它:formvalue.combobox1.SelectedValue.

Change the combobox modifier to public and the you should be able to access it like this: formvalue.combobox1.SelectedValue.

请使用:

experiments.Form1 formvalue=new experiments.Form1();
string cbValue = string.Empty;
if(formvalue.cbLoginCompany.SelectedValue != null)
{
   cbValue = formvalue.cbLoginCompany.SelectedValue.ToString();
}

在构造函数中初始化.

解决方案:字段初始化程序无法引用非静态字段，方法或属性 [

Initialize in the constructor.

Solution : A field initializer cannot reference the nonstatic field, method, or property[^]
