/// <summary>        /// 获取窗体的名称        /// </summary>        /// <param name="hWnd"></param>        /// <param name="lpString"></param>        /// <param name="nMaxCount"></param>        /// <returns></returns>        [DllImport("user32.dll")]        public static extern int GetWindowTextW(IntPtr hWnd, IntPtr lpString, int nMaxCount);          [DllImport("user32.dll")]        static extern int SetWindowText(IntPtr hWnd, string text);        private const int NumChars = 256;        public static string GetWindowTitle(IntPtr hwnd)        {            IntPtr intPtr = Marshal.AllocHGlobal(NumChars);            GetWindowTextW(hwnd, intPtr, 100);            var s = Marshal.PtrToStringUni(intPtr);            Marshal.FreeHGlobal(intPtr);            return s;        }          private async Task StartMyNotepad()        {            IntPtr handle = System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;           var setResult = SetWindowText(handle, "测试进程");            Console.WriteLine(GetWindowTitle(handle));              this.Visibility = Visibility.Collapsed;          }

　　需要再Load完成后再调用 StartMyNotepad()佛足将设置失败
