How to get the latest data in InfluxDB via C#

Question

When I used mongodb before, I used this method to get the latest data in the DB.

double H = Model.LastOrDefault().Ax;
double V = Model.LastOrDefault().Ay;

Does influxdb have similar functions? I am currently obtaining all the information using this method.

@foreach (var record in Model)
{
    <li>@record.Ax</li>
}

it is model

 public class MpuModel
{
    public double Ax { get; set; }
    public double Ay { get; set; }
    
}
