Open button on Messagebox
问题 I have a WinForms application, and when it is finished running, displays a message box with just an OK button. Is it possible to have an OPEN button on the message box too? I found this code online: public static DialogResult Show(string text, string caption, MessageBoxButtons buttons); But it only gives basic commands, like Yes / No , OK / Cancel , etc. It doesn't show any open button. I want to OPEN a text file after my program has finished running. Any help would be greatly appreciated.
