One, the simplest way:
In VS, select the item right-click, open "Properties" and change "output type" to "Windows Application". Save after run find black form gone!
B. Set with code:
<span style= "Font-family:microsoft yahei;font-size:14px;" > #region Hidden window [DllImport ("user32.dll", EntryPoint = "ShowWindow", SetLastError = True)] private static extern bool ShowWindow (IntPtr hWnd, uint ncmdshow); [DllImport ("user32.dll", EntryPoint = "FindWindow", SetLastError = True)] private static extern IntPtr FindWindow (string lpclassname, String lpwindowname); public static void Windowhide (string consoletitle) { IntPtr a = FindWindow ("Consolewindowclass", Consoletitle) ; if (A! = IntPtr.Zero) ShowWindow (A, 0);//Hide window else throw new Exception ("Can ' t hide console window"); #endregion调用方//windowhide (System.Console.Title); Windowhide (System.Console.Title);</span>
