You can't. MessageBox is a special container designed to only show a message and buttons. Instead, you can create your own Form with whatever controls you want, and use .DisplayModal()on it.
你不能。MessageBox 是一个特殊的容器，旨在仅显示消息和按钮。相反，您可以使用您想要的任何控件创建自己的表单，并.DisplayModal()在其上使用。

you could create a classic win form that looks like a message box and opening it as a modal form
perhaps using Form.ShowDialog
您可以创建一个看起来像消息框的经典获胜表单，并将其作为模态表单打开，也许使用 Form.ShowDialog

It will be better to add a new Form in you application which you can customize the way you want.
最好在您的应用程序中添加一个新表单，您可以按照自己的方式自定义。
and just call it from where ever required.
只需从需要的地方调用它。

You cannot customise the MessageBox, its better you use a popup designed using Windows Form separately and use its instance to invoke.
您无法自定义 MessageBox，最好使用单独使用 Windows 窗体设计的弹出窗口并使用其实例进行调用。
customPopup popup = new customPopup();
popup.ShowDialog();
Place your controls on the popup form and set their access modifiers to public if you want to access the textboxes or labels etc in your previous form.
如果您想访问之前表单中的文本框或标签等，请将您的控件放在弹出表单上并将它们的访问修饰符设置为 public。
customPopup popup = new customPopup();
popup.msgLabel.Text= "Your message";
popup.ShowDialog();

Yes, as krillgar mentioned,you should create your own form. And 1. Encapsulate the form in a static class or function, so you may just call MyMessageBox.Show(). 2. The textbox should have readonly=true, so the end users won't be able to change the text displayed, while they could select text and copy to clipboard.
是的，正如 krillgar 提到的，您应该创建自己的表单。并且 1. 将表单封装在静态类或函数中，因此您可以只调用 MyMessageBox.Show()。2. textbox 应该有 readonly=true，所以最终用户将无法更改显示的文本，而他们可以选择文本并复制到剪贴板。
Regarding to item 2, I believe many Windows build applications and MS Office use such approach.
关于第 2 条，我相信许多 Windows 构建应用程序和 MS Office 都使用这种方法。

You can simply add an Input box from VB.NET into your C# project. First add Microsoft.VisualBasicto your project References, then use the following code:
您可以简单地从 VB.NET 添加一个输入框到您的 C# 项目中。首先将Microsoft.VisualBasic添加到您的项目引用中，然后使用以下代码：
string UserAnswer = Microsoft.VisualBasic.Interaction.InputBox("Your Message ", "Title", "Default Response");
And that should work properly.
这应该可以正常工作。

Solution in here, you can create windows form and design it, set form is dialog, when you call form, it is auto show. In form you design, you set value some parameter static where other class in project, but you should set when you close form design that, OK, come back form init call show dialog, you create interval call when have == null return call, when != null you stop call back and using parameter in class static it !
解决方案在这里，你可以创建windows窗体并设计它，设置窗体是对话框，当你调用窗体时，它是自动显示。在你设计的表单中，你在项目中的其他类中设置了一些参数静态的值，但是你应该在关闭表单设计时设置，好的，返回表单初始化调用显示对话框，当有==空返回调用时创建间隔调用，当 != null 时，您将停止回调并在类 static 中使用参数！
