强制创建WPF Window的本机Win32句柄

            // 使用本机Win32句柄进行操作
            // ...

            // 示例：调用本机Win32 API，设置窗口标题
            SetWindowText(handle, "My WPF Window");
        }

        // 本机Win32 API声明
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        private static extern int SetWindowText(IntPtr hWnd, string lpString);
    }
