使用server.MapPath（）时不允许使用相对虚拟路径

Question

I am Trying to get the configuration file using the following code:

public void EncryptConnString()
        {
    Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Server.MapPath(@"/"));
            ConfigurationSection section = config.GetSection("connectionStrings");
            if (!section.SectionInformation.IsProtected)
            {               
                config.Save(ConfigurationSaveMode.Modified);
            }
        }

But i am getting the error

The relative virtual path 'F:/xxxx/yyyy/sample/' is not allowed here.

Note: I am accessing this code in global.asax page What i am doing wrong?

如果将null传递给此方法，它将为您返回根配置文件：

var config = WebConfigurationManager.OpenWebConfiguration(null);
