问题描述

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?

感谢。

推荐答案

好吧，我找到了答案，我真的很期待的。基本上，你需要调用LocalFileSettingsProvider.Upgrade。但是，由于我将使用ClickOnce部署，它会自动为你做它。

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：好吧，但我怎么知道何时调用升级

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

？答：好问题。在ClickOnce的，当你安装你的应用程序的新版本，ApplicationSettingsBase会检测到它，并自动以设定加载点升级你的设置。在非的ClickOnce情况下，没有自动升级 - 您必须调用升级自己。下面是用于确定何时调用升级一个想法：

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一个布尔值设置，并给它真正的默认值。当你的应用程序启动时，你可以这样做：

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;
}

这将确保升级（）被调用仅在第一次运行该应用程序。后一个新版本部署

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