c# - 如果 bool 为真则返回 int

Question

根据选中的单选按钮，我需要一个等于特定值的 int 血型。如果任何 bool 为真，它将使血型等于特定值。我只是不知道如何让 bool 为 int 血型赋值。有什么指点吗？

private void btnAddPatient_Click(object sender, RoutedEventArgs e)////Adds Patients using buttone etc to set properties
    {
        string name = txtPatientName.Text;
        int bloodType,x=1;           
         DateTime dob;
        bool bloodA = rbA.IsChecked.Equals(true);
        bool bloodB = rbB.IsChecked.Equals(true);
        bool bloodAB = rbAB.IsChecked.Equals(true);
        bool blood0 = rb0.IsChecked.Equals(true);



        if (dpDOB.SelectedDate == null || txtPatientName.Text == "" || !bloodA || !bloodAB || !bloodB || !blood0)
        {

            if (txtPatientName.Text == "")
            {
                MessageBox.Show("Please enter Patient's Name");
            }

            else if (dpDOB.SelectedDate == null)
            {
                MessageBox.Show("Please select a date");
            }


            else if(!bloodA || !bloodAB || !bloodB || !blood0)
            {
                MessageBox.Show("Please enter patient's blood type");
            }

        }

        else
        {
            //bloodType  How to make this equal to a value depending on what radio button is checked?
            dob = dpDOB.SelectedDate.Value;

            Patient patient = new Patient(name, bloodType, x, dob);

            MainWindow mainWindow = Owner as MainWindow;

            patients.Add(patient);
            lstPatients.ItemsSource = null;
            lstPatients.ItemsSource = patients;
            // this.Close();
        }
    }

Answer 1

首先，我建议提取类型，准确地说是enum:

  // [Flags] // you may want declare enum as Flags
  public enum BloodType {
     O = 0,
     A = 1,
     B = 2,
    AB = 3
  }

然后你可以在三元运算符的帮助下分配BloodType值:

  BloodType bloodType = 
      rb0.IsChecked ? BloodType.O 
    : rbA.IsChecked ? BloodType.A
    : rbB.IsChecked ? BloodType.B
    : BloodType.AB;  

如果你想得到 int 值，只需转换:

 int v = (int) bloodType;

 BloodType t = (BloodType) v;
