加密 app.config 后无法识别的属性“configProtectionProvider" [英] Unrecognized attribute 'configProtectionProvider' after encrypting app.config

问题描述

我在我的应用程序开始时运行以下方法，传入一个位于 applicationSettings 下的部分:

I run the following method at the beginning of my application passing in a section living under applicationSettings:

public static void EncryptConfigSection(string sectionKey)
    {
        Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        ConfigurationSection section = config.GetSection(sectionKey);
        if (section != null)
        {
            if (!section.SectionInformation.IsProtected)
            {
                if (!section.ElementInformation.IsLocked)
                {
                    section.SectionInformation.ProtectSection("RSAProtectedConfigurationProvider");
                    section.SectionInformation.ForceSave = true;
                    config.Save(ConfigurationSaveMode.Full);
                    ConfigurationManager.RefreshSection(sectionKey);
                }
            }
        }
    }

以下是 app.config 部分的示例:

Here's an example of the section in the app.config:

<applicationSettings>
  <Example.Properties.Settings>
    <setting name="Key" serializeAs="String">
      <value>Value</value>
    </setting>
  </Example.Properties.Settings>
</applicationSettings>

当我尝试访问该部分的任何设置时，收到以下错误:

When I try to access any of the settings from the section, I receive the following error:

无法识别的属性configProtectionProvider"

Unrecognized attribute 'configProtectionProvider'

这是一个桌面应用，启动时需要加密一些设置，退出时需要解密.

This is a desktop application that needs to encrypt some settings when starting then decrypt when exiting.

有没有人有解决这个问题的方法?

Does anyone have a solution for this issue?

推荐答案

我无法在应用程序运行时加密/解密配置文件并继续读取值.

I was not able to encrypt/decrypt the config file while the application was running and continue to read the values.

虽然不是我想要的，但解决问题的方法是在应用程序运行之前先加密/解密 .config.

Although not what I wanted, the solution to the problem was to first encrypt/decrypt the .config before the application ran.

这是另一种我没有做过但看起来很有趣的方法:加密.NET app.config 文件中的密码

Here is another approach which I didn't do but seemed interesting: Encrypting Passwords in a .NET app.config File
