Answer 1

public class GenderPicker : UIViewController
{
    public TestVC() { }


    UITextField SelectGenderTextField = new UITextField();
    UIPickerView GenderPicker = new UIPickerView();

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        AddTextField();
        GenderTextField();


        Constraint();
    }
}

Textfield To Show The Selected Data

    private void AddTextField()
    {
        SelectGenderTextField.Placeholder = "Select Gender";
        SelectGenderTextField.Layer.BorderWidth = 1;
        SelectGenderTextField.Layer.BorderColor = UIColor.Black.CGColor;
        SelectGenderTextField.Layer.MasksToBounds = true;
        SelectGenderTextField.Layer.SublayerTransform = CATransform3D.MakeTranslation(5, 0, 0); //to Create a Space At The beginning of the text field


        SelectGenderTextField.InputView = GenderPicker; //To Start The UIPickerView from The bottom.

    }

Gender Picker

    private void GenderTextField()
    {
        var genderList = new List {
       "Male","Female"
    };

        var picker = new GenderPickerModel(genderList);

        GenderPicker.Model = picker;

        picker.ValueChanged += (sender, e) => {

            SelectGenderTextField.Text = picker.SelectedGenderByUser; //Update The Selected Value In the TextField

            View.EndEditing(true);// To Dismiss the Picker View Once The User Select The Value
        };

     }

Constraints

    // Used Cirrious.FluentLayouts.Touch For Constraints
    private void Constraint()
    {
        View.AddSubviews(SelectGenderTextField);

        View.SubviewsDoNotTranslateAutoresizingMaskIntoConstraints();

        View.AddConstraints(


            SelectGenderTextField.WithRelativeWidth(View, 0.80f),
            SelectGenderTextField.WithRelativeHeight(View, 0.05f),
            SelectGenderTextField.WithSameCenterX(View),
            SelectGenderTextField.WithSameCenterY(View)


            );
    }

Picker Model Class

class GenderPickerModel : UIPickerViewModel
{
    public EventHandler ValueChanged;
    public string SelectedGenderByUser;
    private List genderList;

    public GenderPickerModel(List genderList)
    {
        this.genderList = genderList;
    }

    public override nint GetRowsInComponent(UIPickerView pickerView, nint component)
    {
        return genderList.Count;
    }

    public override nint GetComponentCount(UIPickerView pickerView)
    {
        return 1;
    }

    public override string GetTitle(UIPickerView pickerView, nint row, nint component)
    {
        return genderList[(int)row];
    }

    public override void Selected(UIPickerView pickerView, nint row, nint component)
    {
        var gender = genderList[(int)row];
        SelectedGenderByUser = gender;
        ValueChanged(null,null);
    }
