從組合框中返回兩個值

Question

在我的程序中，我將值存儲在列表中。我需要從一個組合框中返回這些值中的兩個。我在互聯網上搜索，但無法找到答案。請給我一些提示。 這裏是我的代碼：

價值觀列表：

public class ActualCurrencyBoxData 
{ 
    public string displayValue { get; private set; } 
    public decimal currencyCourse { get; set; }  
    public int currencyConverter { get; set; } 

    public ActualCurrencyBoxData(string ncurrencyName, string ncurrencyCode, decimal ncurrencyCourse, int ncurrencyConverter) 
    { 
     displayValue = ncurrencyName +" (" +ncurrencyCode+ ")"; 
     currencyCourse = ncurrencyCourse;   
     currencyConverter = ncurrencyConverter;   
    } 

} 

我只能返回一個值（actualCurrencyCourse，我還需要currencyConverter）：

List<ActualCurrencyBoxData> checkBoxVal = new List<ActualCurrencyBoxData>(); 

public void CurrencyBoxLoad(object sender, RoutedEventArgs e) 
{ 
    var comboBox = sender as ComboBox; 
    comboBox.ItemsSource = checkBoxVal; 
    comboBox.DisplayMemberPath = "displayValue"; 
    comboBox.SelectedValuePath = "currencyCourse";         
} 

private void Count_Click(object sender, RoutedEventArgs e) 
{  
    actualCurrencyCourse = ActualCurrencyBox.SelectedValue.ToString()); 
} 

Answer 1

可以使用SelectedItem財產，而不是獲得選定的項目的對象：

private void Count_Click(object sender, RoutedEventArgs e) 
{  
    actualCurrencyCourse = ((ActualCurrencyBoxData)ActualCurrencyBox.SelectedItem).currencyCourse; 
    actualCurrencyConverter = ((ActualCurrencyBoxData)ActualCurrencyBox.SelectedItem).currencyConverter; 
}
