XUnit is Not Executing Code Inside String Before Comparing Expected/Actual

I have the following code with simple string interpolation:

public string CreateStyledGuestList(VolunteerDTO volunteerData)
{
  List<GuestContact> guestListWithLeaderIncluded = GetNewGuestListWithLeaderIncluded(volunteerData);

  string styledGuestList = 
    "<div style=\"margin-left: 40px\">"
    + "<br>" + guestListWithLeaderIncluded.Select(g => g.FirstName + " " + g.LastName)
    + "</div>";

  return styledGuestList;
}

When I test this method, I get the following (note that the code is shown, instead of the resulting string):

                             ↓ (pos 35)

Expected: ···gin-left: 40px">
Leeroy Jenkins Actual: ···gin-left: 40px">
System.Linq.Enumerable+SelectListIterator··· ↑ (pos 35)

The test itself:

[Fact]
public void ShouldCreateGuestListWithOnlyLeader()
{
  VolunteerDTO volunteerData = new VolunteerDTO();
  volunteerData.FirstName = "Leeroy";
  volunteerData.LastName = "Jenkins";
  volunteerData.Guests = new List<GuestContact>();

  string actual = _fixture.CreateStyledGuestList(volunteerData);
  string expected =  "<div style=\"margin-left: 40px\"><br>Leeroy Jenkins</div>";

  Assert.Equal(expected, actual);
}

Why is the string not being interpolated / how do I fix this?

guestListWithLeaderIncluded.Select(...) will return an IEnumerable<string> and not a string

You need to join the strings to one string like:

... + string.Join("<br>", guestListWithLeaderIncluded.Select(...)) + ...
