When debugging my project in Visual Studio 2008, my Settings.settings file keeps getting reset between builds. Is there a way to prevent this from happening?

谢谢.

推荐答案

好的，我找到了我真正想要的答案.基本上，您需要调用 LocalFileSettingsProvider.Upgrade.但是，由于我将使用 ClickOnce 进行部署，因此它会自动为您完成.

Okay, I found out the answer I was really looking for. Basically, you need to call LocalFileSettingsProvider.Upgrade. However, since I will be deploying using ClickOnce, it will do it for you automatically.

问:好的，但我怎么知道什么时候调用升级?

Q: Okay, but how do I know when to call Upgrade?

答:好问题.在 Clickonce 中，当您安装新版本的应用程序时，ApplicationSettingsBase 将检测到它并在加载设置时自动为您升级设置.在非 Clickonce 的情况下，没有自动升级 - 您必须自己调用 Upgrade.以下是确定何时调用升级的一种方法:

A: Good question. In Clickonce, when you install a new version of your application, ApplicationSettingsBase will detect it and automatically upgrade settings for you at the point settings are loaded. In non-Clickonce cases, there is no automatic upgrade - you have to call Upgrade yourself. Here is one idea for determining when to call Upgrade:

有一个名为 CallUpgrade 的布尔值设置，并给它一个默认值 true.当您的应用启动时，您可以执行以下操作:

Have a boolean setting called CallUpgrade and give it a default value of true. When your app starts up, you can do something like:

if (Properties.Settings.Value.CallUpgrade)
{
    Properties.Settings.Value.Upgrade();
    Properties.Settings.Value.CallUpgrade = false;
}

这将确保仅在部署新版本后第一次运行应用程序时调用 Upgrade().

This will ensure that Upgrade() is called only the first time the application runs after a new version is deployed.
