我尝试加密网络的连接字符串部分。配置文件。Web应用程序通过一个简单的winforms应用程序。我以管理员的身份运行VS2010，并运行以下代码。

private void encryptButton_Click(object sender, EventArgs e)
        {
            Configuration config = GetConfiguration();
            ConfigurationSection configSection = config.GetSection("connectionStrings");
            if (configSection != null)
                // Only encrypt the section if it is not already protected
                if (!configSection.SectionInformation.IsProtected)
                {
                    configSection.SectionInformation.ProtectSection(
                        "DataProtectionConfigurationProvider");
                    configSection.SectionInformation.ForceSave = true;
                    config.Save();
                    DisplayWebConfig();
                }
        }
private Configuration GetConfiguration() 
        {
            var configFile = new FileInfo(@"C:'Users'abalawan'Desktop'CN'R13 new'Websites'ABC");
            var vdm = new VirtualDirectoryMapping(configFile.DirectoryName,true,configFile.Name);
            var wcfm = new WebConfigurationFileMap();
            wcfm.VirtualDirectories.Add("/",vdm);
            return WebConfigurationManager.OpenMappedWebConfiguration(wcfm, "/");
        }

由于我只有物理路径，我试图将路径映射到相应的虚拟路径。但是config.Save()给了我以下错误

ConfigurationErrorsException was unhandled.
Unable to save config to file 'C:'Users'abalawan'Desktop'CN'R13 new'Websites'ABC'.

无法更新和保存网页.配置文件

你的代码是完美的。似乎有许可问题。暂时试着让所有人都能访问你的文件位置。如果它工作，那么它的权限问题(虽然给每个人完全的权限不是一个好主意)

如果你想在你的应用程序中添加UAC权限，那么你可以添加app.manifest文件，并在该文件中更改requestdexecutionlevel标签，如下所示:

    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
