当用户单击Win表单中的Cancel时，取消安装 [英] Canceling Installation when user click cancel in win form

问题描述

你好，

我已经开发了安装程序安装项目.在安装过程中，我将Windows应用程序用作自定义操作.在这里，我将显示取消"按钮.如果用户单击取消"按钮或关闭表单，则设置也不应继续.意味着当用户以Win形式取消安装时，安装程​​序也应该关闭.

请帮我怎么办?

谢谢.

推荐答案

这里是解决方案

如果需要回滚异常，则抛出安装异常，该异常将自动回滚安装程序.

Here''s the solution

In case you need to rollback on a exception throw the install exception which will automatically rollback the setup.

throw new InstallException("Missing database script file");

嗨Birajdar，

在出现错误或取消后，它不会停止设置的继续.它照常运行.在安装过程中，我正在使用winform.假设如果我在winform中出错，则安装程序应该停止并且应该回滚.那怎么办?

现在，我在安装过程中覆盖了安装方法.以及如何将错误消息重新传递给安装程序.请引导我.
