情況:我得到了3個互相協作的課程。 1:主(圖形用戶界面) 2:比較(比較值) 3:CompareData(繼承列表值)獲得列表中最低項目的最佳方式
我想取兩個值:一個字符串和一個雙,並把它們放在一個名單。當然,最後還會有不止一個列表項目。列表填好後,我想用字符串得到最低的兩倍,並將它們放在一個標籤中。
這裏是我到目前爲止有:
主營:
public class GlobaleDaten //The second List: VglDaten is the one for my situation
{
public static List<Daten> AlleDaten = new List<Daten>();
public static List<Vgl> VglDaten = new List<Vgl>();
}
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
[...Some Code thats not relevant...]
//addListAb adds values in a ListBox and should also
//place them into the list VglDaten
public void addListAb()
{
listBox.Items.Add(Abzahlungsdarlehenrechner.zgName + " " + "[Abzahlungsdarlehen]" + " " +Abzahlungsdarlehenrechner.zmErg.ToString("0.00") + "€" + " " + Abzahlungsdarlehenrechner.zgErg.ToString("0.00") + "€");
Vgl comp = new Vgl();
comp.name = Abzahlungsdarlehenrechner.zgName;
comp.gErg = Abzahlungsdarlehenrechner.zgErg;
GlobaleDaten.VglDaten.Add(comp);
}
//bVergleich should compare these values from the list
//and show the lowest value in a label
public void bVergleich_Click(object sender, RoutedEventArgs e)
{
if (listBox.Items.Count <= 0)
{
MessageBox.Show("Bitte erst Einträge hinzufügen.");
}
else
{
VglRechner vglr = new VglRechner();
vglr.Compare();
lVergleich.Content = VglRechner.aErg + " " + "€";
}
}
CompareData:
//Only used for storing the values
public class Vgl : Window
{
public string name { get; set; }
public double gErg { get; set; }
}
比較:
public class VglRechner
{
public static string aName;
public static double aErg;
public void Compare(Vgl comp)
{
//I'm not sure if this is the right way to compare the values
//correct me if I'm wrong please :)
double low = GlobaleDaten.VglDaten.Min(c => comp.gErg);
aErg = low;
aName = comp.name;
}
}
的作品比較完美,謝謝:)不過我有一個問題:當我想設置的標籤aErg的價值和aName它仍然是儘管VglRechner.aErg是正確的,不是嗎? –
對我的評論:與你或我的代碼無關。這個標籤有一個錯誤的屬性,抱歉讓你感到困惑:) –
