类型或名称空间名称'frmAbout'在名称空间'DevExpress.Utils.About'中不存在

Question

刚刚升级到DevExpress 18.1.5，我的应用程序无法编译，因为DevExpress.Utils.About.frmAbout无法解析。 DevExpress是否用其他东西代替了？

<?php

define('DB_NAME','testdb');
define('DB_USER','root');
define('DB_PASSWORD','password');
define('DB_HOST','localhost');

//Connecting to sql db
$connect = new mysqli('DB_HOST','DB_USER','DB_PASSWORD','DB_NAME');
if (!$connect) { die ('could not connect'); }
echo 'connection successful'; 

$message = $connect->query("SELECT first_name FROM testtable");

echo "$message <br/>";
echo "hello world";
$connect->close();
?>

Answer 1

DevExpress响应：

是的，我们对版本18.1中的frmAbout对话框进行了重新设计。现在，您可以使用我们的DevExpress.Utils.About.AboutHelper类显示对话框，如下所示：

DevExpress.Utils.About.AboutHelper.Show(DevExpress.Utils.About.ProductKind.DXperienceWin, new DevExpress.Utils.About.ProductStringInfoWin(DevExpress.Utils.About.ProductInfoHelper.PlatformWinForms));
