问题:我有2个表格。一个是ListBox,另一个是Form按钮。我想在第二种形式中触发按钮时添加一个ListBox项。尝试使用以下代码,计算有效,但由于某种原因,它不会将项目添加到ListBox。
使用ListBox的表单:
public void addList(string sName)
{
listBox.Items.Add(sName + " " + Annuitätenrechner.zgErg.ToString("0.00") + "€" + " " + Annuitätenrechner.zmErg.ToString("0.00") + "€");
}
使用按钮填写表格:
public void bAdd_Click(object sender, RoutedEventArgs e)
{
string sMonate = monate2.Text;
string sZins = zins2.Text;
string sName = name2.Text;
if ((monate2.Text == "" && zins2.Text == "") || (sMonate.Contains('-')) || (sZins.Contains('-')))
{
MessageBox.Show("Die eingegebenen Werte müssen größer als 0 sein.");
}
else
{
Daten data = new Daten();
data.AnBetrag = int.Parse(betrag2.Text);
data.AnMonate = int.Parse(monate2.Text);
data.AnZins = double.Parse(zins2.Text) / 100;
GlobaleDaten.AlleAnnuitaeten.Add(data);
Annuitätenrechner annuitätenrechner = new Annuitätenrechner();
annuitätenrechner.AnRechner(data);
MainWindow mainwindow = new MainWindow();
mainwindow.addList(sName);
}
}
随时询问您是否需要更多信息。

将FormWithListBox的引用发送到FormWithButton,示例:
public class FormWithListBox
{
private void openFormWithButton()
{
var formWithButton = new FormWithButton(this);
formWithButton.Show();
}
public void addList(string sName)
{
listBox.Items.Add(...);
}
}
public class FormWithButton
{
private readonly FormWithListBox _form;
public FormWithButton(FormWithListBox form)
{
_form = form;
}
public void bAdd_Click(object sender, RoutedEventArgs e)
{
_form.addList("...BlaBlaBla...");
}
}
