更新Web.config加密的Connstring

Question

使用代码在web.config上出现问题：

Configuration config = ConfigurationManager.OpenExeConfiguration(webConfigFile);

        ConfigurationSection constring_section = config.GetSection(section);
        if (constring_section != null && !constring_section.SectionInformation.IsProtected)
        {
            constring_section.SectionInformation.ProtectSection(provider);
            config.Save();

        }
    }

然而，该代码有效，而不是更新实际的“ web.config”（webConfigFile的值），它创建了“ web.config.config”，并且仅包含connectionStrings部分：

<connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
    <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"
        xmlns="http://www.w3.org/2001/04/xmlenc#">
        <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes256-cbc" />
        <KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
            <EncryptedKey xmlns="http://www.w3.org/2001/04/xmlenc#">
                <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5" />
                <KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
                    <KeyName>Rsa Key</KeyName>
                </KeyInfo>
                <CipherData>

找出解决方案，

关于OpenExeConfiguration与OpenMappedExeConfiguration的用法

OpenMappedExeConfiguration vs. OpenExeConfiguration

所以来自：

配置配置= ConfigurationManager.OpenExeConfiguration（webConfigFile）;

    ConfigurationSection constring_section = config.GetSection(section);
    if (constring_section != null && !constring_section.SectionInformation.IsProtected)
    {
        constring_section.SectionInformation.ProtectSection(provider);
        config.Save();

    }
}

to

Configuration config = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap() { ExeConfigFilename = webConfigFile} , ConfigurationUserLevel.None);
        ConfigurationSection constring_section = config.GetSection(section);
        if (constring_section != null && !constring_section.SectionInformation.IsProtected)
        {
            constring_section.SectionInformation.ProtectSection(provider);
            config.Save();
        }
