Can I reinitialise (set to default values) all the user specific variables , defined in a Blazor Server app's Scoped Service with one command in C#?

I have a Blazor server side app. All the user specific variables I have defined in a scoped service. (TagService). With my app the user can connect to a production machine and read their PLC and CNC data. If the user disconnects from the current machine, I want that all the variables that are defined in the scoped service are initialized to their defined default values (Like 0 or "") I do that normally in a classic way shown in the code below.

When the user clicks the disconnect button I call a function in the scoped service where I set all the user specific variables to their default values one by one. I have few hundred variables and I loose more and more the overview in this way.

Is there an easier way, so that I can reinitialize all the variables in a scoped service to their initial values with just one command instead of setting back their values one by one to their default values?

Razor page code

@inject TagService TagService
<button @onclick="Disconnect">Disconnect</button>
private void Disconnect()
{
    TagService.Delete_UserTags();
}

Scoped Service (TagService)

public class TagService
{
  public int Tag1=0;
  public int Tag2=0;
  public int Tag3=1;
  public string Tag4="";
  // few hundred Tags      

  public void Delete_UserTags()
    {
     Tag1=0;
     Tag2=0;
     Tag3=0;
     Tag4="";
     //setting all the few hundred tags to their initial value
    }
}
