Code
  protected void Page_Load(object sender, EventArgs e)
    {
        Configuration config = WebConfigurationManager.OpenWebConfiguration(this.Request.ApplicationPath);
        MailSettingsSectionGroup smtp = (MailSettingsSectionGroup)config.GetSectionGroup("system.net/mailSettings");

        Response.Write(smtp.Smtp.Network.Host);
    }
    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {

        try
        {
            getAppSettings(out myConfiguration, out myAppSettings);
            if (!myAppSettings.SectionInformation.IsProtected)
            {
                myAppSettings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
                myConfiguration.Save();
                Response.Write("success jiami");
            }
        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }
    }
    protected void getAppSettings(out Configuration myconfig, out ConfigurationSection appSettings)
    {
        myconfig = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
        appSettings = myconfig.GetSection("appSettings");
    }

    protected void Button3_Click(object sender, EventArgs e)
    {
        try
        {
            getAppSettings(out myConfiguration, out myAppSettings);
            if (myAppSettings.SectionInformation.IsProtected)
            {
                myAppSettings.SectionInformation.UnprotectSection();
                myConfiguration.Save();
            }
            Response.Write("success jiemim");
        }

        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }

    }
}

以上就可以对appsettings的区块内容加密了，使用"DataProtectionConfigurationProvider"进行DPAPI加密

用"RSAProtectionConfigurationProvider"就可以进行RSA加密了，只要改改provider就可以了。

用简单的UnprotectSection()就可以解密了

如果对数据库连接字符串部分加密可以用

myConfig=GetSection("connectionStrings");

就可以了

用aspnet_regiis -pe(加密,解密用-pd) “connectionStrings" -app "虚拟目录，在c:\intpub\wwwroot中" -prov "加密方式"
