我有一个加密的配置文件中的部分应用程序。在我第一次尝试读取配置文件，我得到一个错误信息加密的部分：无法识别的属性configProtectionProvider请注意，属性名称是区分大小写的。

I have an application that encrypts a section in the configuration file. In the first time that I try to read the encrypted section from the config file I get an error message: "Unrecognized attribute 'configProtectionProvider'. Note that attribute names are case-sensitive. "

config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);  
// Get the section in the file.   
ConfigurationSection section = config.GetSection("EncryptedSection");


if (section != null)      
{           
    // Protect the section.
    section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
    section.SectionInformation.ForceSave = true;

    // Save the change.

    config.Save(ConfigurationSaveMode.Modified);  
}  
ConfigurationManager.RefreshSection("EncryptedSection");  
Properties.Settings.Default.Reset();

//This is the part where I read the encrypted section:

ConfigurationManager.RefreshSection("EncryptedSection");
System.Collections.IDictionary HSMMasterKeyConfig = (System.Collections.IDictionary)System.Configuration.ConfigurationManager.GetSection("EncryptedSection");

这只是发生在我第一次尝试读取加密的部分。我注意到，该config文件中得到后立即更新了先救但从某种原因，我需要重新启动应用程序才能使用加密的部分。

This only happens in the first time that I try to read the encrypted section. I have noticed that the .config file is getting updated immediately after the first save but from some reason I need to restart the application in order to use the encrypted section.

推荐答案

供您参考的问题是，这是试图将配置部分进行加密没有管理员权限的进程。我说这过程中对管理员组，并且解决它。

For your reference the issue was that the process that was trying to encrypt the config section didn't have admin rights. I added this process to the administrators group and that solved it.
