通过点击一次部署在更新中持久化app.config变量 [英] Persisting app.config variables in updates via Click once deployment

问题描述

每次点击一次的应用程序发布新的更新时，app.config文件中的变量将被销毁。

Every time a new update is released for an application with click once, the variables in the app.config file are destroyed

<userSettings>
    <app.My.MySettings>
      <setting name="Email" serializeAs="String">
        <value />
      </setting>
      <setting name="UserName" serializeAs="String">
        <value />
      </setting>
    </app.My.MySettings>
  </userSettings>

我该如何防止？

有没有办法从以前的应用程序版本中修改变量？

Is there any way of feching the variables from the previous application version?

推荐答案

有没有选中应用程序应该检查更新选项？

Do you have the "Applications should check for updates" option checked?

看看探索持久应用程序设置的秘密（标题为维护程序版本之间的设置）：

Have a look at Exploring Secrets of Persistent Application Settings (the section titled "Maintaining Settings Between Program Versions"):

对于与
以前版本中的设置相匹配的当前
版本的任何设置，此例程将
导入到当前版本的
user.config文件：

For any settings from the current version that match settings in the prior version, this routine will import them into the current version's user.config file:

在程序的入口点放置以下代码。

At the entry point to your program, place the following code.

if (Properties.Settings.Default.UpgradeSettings) 
{
   Properties.Settings.Default.Upgrade();
   Properties.Settings.Default.UpgradeSettings = false;
}

请注意，UpgradeSettings是布尔型用户设置而不是应用程序）您需要添加自己，并且您希望默认值为 True 。

Note that UpgradeSettings is a boolean user setting (not application) that you need to add yourself, and you want the default value to be True.
