从组合框中返回两个值

Question

在我的程序中，我将值存储在列表中。我需要从一个组合框中返回这些值中的两个。我在互联网上搜索，但无法找到答案。请给我一些提示。 这里是我的代码：

价值观列表：

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;   
    } 

} 

我只能返回一个值（actualCurrencyCourse，我还需要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财产，而不是获得选定的项目的对象：

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