我正在尝试为我正在处理的项目创建自己的错误窗口.当我显示我的错误窗口时,我无法将错误消息和用户消息传递给错误窗口,因为在我创建的类中无法看到"ErrorMessage.Text".
我进入了表单设计器生成的代码并尝试使TextBox保持静态,但这只会破坏事物.我可以将TextBox设为public/static,以便我可以从另一个表单中更改它吗？
编辑:
好的,有关更多信息......
我创建了自己的表单.它被称为"formErrorWindow".我需要显示我使用其他表单中的消息集预先设计的表单.我能做到这一点的唯一方法是,如果我在窗体设计器区域中为窗体创建一个Function,并使用"this.errorMsg.text = error"设置变量.我能看到该功能的唯一方法是将其设置为静态.如果我将函数设置为静态,当我尝试将"this.errorMsg.Text = error"时,我得到此错误:非静态字段,方法或属性需要对象引用.
这是我尝试过的:

寻找我上面添加的功能.我如何编译并执行我想要它做的事情没有我一直得到的错误:非静态字段,方法或属性需要对象引用.
我只是将消息作为构造函数参数传递.
MyMessageBox messageBox = new MyMessageBox("My error message");
messageBox.Show();
