Is there something like a horizontal line (i.e. <hr>) that can be used for C# Message Box?

Question

For example instead of doing the ("\\n-----------------"); for a MessageBox.Show(); function, is there an in-build horizontal line generator similar to the HTML <hr> ?

Answer 1

A messagebox is a simple element for showing plain text. It does not have much design features.

However you can easily create a new form, put in its text and show it using Form.ShowDialog . Now you can add any design-element you want by chosing it in the toolbox, eg by using a 2px label as shown here .

You could also implement the syntax you know from MessageBox by using a static method:

public class CustomMessageBox : Form
{
    private readonly static instance = new CustomMessageBox();
    private DialogResult result = DialogResult.No;

    private CustomMessageBox()
    {
        btnOK.DialogResult = DialogResult.OK;
        btnCancel.DialogResult = DialogResult.Cancel;
        this.AcceptButton = btnOK;
        this.CancelButton = btnCancel;
    }
    public static DialogResult Show(string text)
    {
        return instance.ShowDialog();
    }
}

Create a form, and send the message in your constructor or in function. And set the available buttons that you want to see... That way you can handle the response-buttons
