iterate through class properties c#

Question

Currently I have a method to create a filter which filters by name, address and age using regex in my c# backend. I want to remove the if conditions and use a loop instead. How can I do that?

This is my current method.

private static FilterMethod<Logs> GetFilter(Parameters parameters, DateTime startDate, DateTime endDate)
{
    var filter = Builders<Logs>.Filter.Gte(x => x.Date, startDate);
    
    filter &= Builders<Logs>.Filter.Lte(x => x.Date, endDate);
    
    if (!string.IsNullOrEmpty(parameters.Name)) 
    { 
        filter &= Builders<Logs>.Filter.Regex(
            "Name", 
            new BsonRegularExpression(parameters.Name, "mi")); 
    }
    
    if (!string.IsNullOrEmpty(parameters.Address)) 
    { 
        filter &= Builders<Logs>.Filter.Regex(
            "Address", 
            new BsonRegularExpression(parameters.Address, "mi")); 
    }
    
    if (!string.IsNullOrEmpty(parameters.Age)) 
    { 
        filter &= Builders<Logs>.Filter.Regex(
            "Age", 
            new BsonRegularExpression(parameters.Age, "mi")); 
    }

    return filter;
}

This is my model class

    public class Parameters
{
    public string Name { get; set; }

    public string Address { get; set; }

    public string Age { get; set; }
}

Here startDate and endDate are not null. Always I am passing the current date from frontend.

I have to use dictionary to get the input parameters. Can someone help?

Thank you!!
