C＃创建Web.config文件编程

问题描述

我在写和安装ASP.NET应用程序，和我有几个数据字段（连接字符串，SMTP服务器等），我想要的安装程序来构建从用户的输入，加密和存储在Web.config文件。我遇到的问题是，无论WebConfigurationManager和ConfigurationManager中都设计工作，关闭现有的配置文件。我怎样才能构建一个新的配置文件，并保存之前对其进行加密？

I'm writing and installer for an ASP.NET application, and I have a few data fields, (connection strings, smtp servers, etc), that I want the installer to build from user input, encrypt and store in the Web.config file. The issue I am having is that both WebConfigurationManager and ConfigurationManager are both designed to work off existing configuration files. How can I construct a new configuration file, and encrypt it before saving it?

推荐答案

我会建议先从不包含你想要的字段，然后使用一个基本配置文件的XDocument 或 WebConfigurationManger 添加配置信息，并对其进行加密。

I would recommend starting with a base configuration file that does not contain fields you want, then using XDocument or WebConfigurationManger add the configuration information and encrypt it.

Code incase the content goes down:

private void EncryptConfig()
{
    // Open the Web.config file.
    Configuration config =
        WebConfigurationManager.OpenWebConfiguration("~");
    // Get the connectionStrings section.
    ConnectionStringsSection section =
    config.GetSection("connectionStrings") as ConnectionStringsSection;

    // Toggle encryption.
    if (section.SectionInformation.IsProtected)
    {
        section.SectionInformation.UnprotectSection();
    }
    else
    {
    if (!section.SectionInformation.IsLocked)
    {
        section.SectionInformation
               .ProtectSection("RsaProtectedConfigurationProvider");

        section.SectionInformation.ForceSave = true;

        //Save changes to the Web.config file.
        config.Save(ConfigurationSaveMode.Full);           }
    }
}
