Wie kann ich eine Listbox -Liste drucken? ⇐ C#

[Anonymous]

Ich habe gerade Probleme mit meinem Code, um eine Druckoption zu erhalten, die angezeigt werden kann, wenn Sie auf eine bestimmte Taste klicken. Sie möchten auch den effizientesten Weg kennen, um meinem Programm ein tägliches Benachrichtigungssystem hinzuzufügen < /p>

Code: Select all

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.Runtime.InteropServices;

namespace simpleapp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
listBox1.Items.Add("Reminder: " + textBox1.Text);
}

private void input_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyData == Keys.Enter)
{
listBox1.Items.Add("Reminder: " + textBox1.Text  );
}
}

private void button2_Click(object sender, EventArgs e)
{
for (int rmd = listBox1.SelectedIndices.Count - 1; rmd >= 0; rmd--)
{
listBox1.Items.RemoveAt(listBox1.SelectedIndices[rmd]);
}
}

private void Form1_Load(object sender, EventArgs e)
{
listBox1.SelectionMode = SelectionMode.MultiExtended;
}

private void button6_Click(object sender, EventArgs e)
{
FAQ faqs = new FAQ();
faqs.Show();
}

// When the Button is Clicked the List is saved in a ".txt file format for the user to view later
private void button3_Click(object sender, EventArgs e)
{
var Savingfileas = new SaveFileDialog();
Savingfileas.Filter = "Text (*.txt)|*.txt ";
if (Savingfileas.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
using (var Reminder = new StreamWriter(Savingfileas.FileName, false))
foreach (var item in listBox1.Items)
Reminder.Write(item.ToString() + Environment.NewLine);
MessageBox.Show("File has been successfully saved"+ '\n' + "Thank you for using the Remindr program");
}
}

private void button4_Click(object sender, EventArgs e)
{

}

private void button5_Click(object sender, EventArgs e)
{
Email_Client emc = new Email_Client();
emc.Show();
}
}
}
