Hey fawwwaz, Check the remainder when every element in 'List1' is divide by 2. If the remainder is 0 then add that 'List1' element to 'List2' else add that 'List1' element to 'List3'. Like this,

void b1_Click(object sender, EventArgs e)
{
l2 = new List<int>();
l3 = new List<int>();

for (int i = 0; i < l1.Count; i++)
{
if (l1[i] % 2 == 0)
l2.Add(l1[i]);
else
l3.Add(l1[i]);
}

Console.WriteLine("Iist 2");
            
foreach (var item in l2)
{
Console.WriteLine(item);
}

Console.WriteLine("Iist 3");

foreach (var item in l3)
{
Console.WriteLine(item);
}
}

Note: l1, l2 and l3 are List<int> type and b1 is Button.

thanks
but it doesn't work

I think the code is:

  Dim reminder As Double

        For i = 0 To (listone.Items.Count() - 1)
            If reminder Mod 2 = 0 Then
                listtow.Items.Add(listone.Items.Item(i))
            Else
                listthree.Items.Add(listone.Items.Item(i))
            End If
        Next
    End Sub

but this code wrong its need something to solve

Please use code tags when posting code.

Use i instead of reminder.

Hey @fawwwaz you using 'List' or 'ListBox' in your code? If you using 'List' like as you mentioned in your question then my code is right. If you want Visual Basic code then use the following code,

Imports System
Imports System.Collections.Generic
Imports System.Windows.Forms

Namespace WindowsFormsApplication1
	Public Partial Class Form1
		Inherits Form
		Private listOne As List(Of Double)
		Private listTwo As List(Of Double)
		Private listThree As List(Of Double)
		Private button1 As Button

		Public Sub New()
			InitializeComponent()
		End Sub

		Private Sub Form1_Load(sender As Object, e As EventArgs)
			listOne = New List(Of Double)()
			button1 = New Button()
			button1.Text = "Split"
			button1.Location = New System.Drawing.Point(100, 100)
			button1.Click += button1_Click
			Controls.Add(button1)

			Dim i As Integer = 0
			While i < 25
				listOne.Add(Convert.ToDouble(i))
				System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
			End While
		End Sub


		Private Sub button1_Click(sender As Object, e As EventArgs)
			listTwo = New List(Of Double)()
			listThree = New List(Of Double)()

			Dim i As Integer = 0
			While i < listOne.Count
				If listOne(i) Mod 2 = 0 Then
					listTwo.Add(listOne(i))
				Else
					listThree.Add(listOne(i))
				End If
				System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
			End While

			Console.Write(vbLf & "Iist 1 ->")

			Dim i As Integer = 0
			While i < listOne.Count
				Console.Write(" " + listOne(i))
				System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
			End While

			Console.Write(vbLf & "Iist 2 ->")

			Dim i As Integer = 0
			While i < listTwo.Count
				Console.Write(" " + listTwo(i))
				System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
			End While

			Console.Write(vbLf & "Iist 3 ->")

			Dim i As Integer = 0
			While i < listThree.Count
				Console.Write(" " + listThree(i))
				System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
			End While
		End Sub
	End Class
End Namespace

Else if you want C# code then use the following code,

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {

        List<double> listOne;
        List<double> listTwo;
        List<double> listThree;
        Button button1;        

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            listOne = new List<double>();
            button1 = new Button();
            button1.Text = "Split";
            button1.Location = new System.Drawing.Point(100, 100);
            button1.Click += button1_Click;
            Controls.Add(button1);

            for (int i = 0; i < 25; i++)
            {
                listOne.Add(Convert.ToDouble(i));
            }
        }


        void button1_Click(object sender, EventArgs e)
        {
            listTwo = new List<double>();
            listThree = new List<double>();

            for (int i = 0; i < listOne.Count; i++)
            {
                if (listOne[i] % 2 == 0)
                    listTwo.Add(listOne[i]);
                else
                    listThree.Add(listOne[i]);
            }

            Console.Write("\nIist 1 ->");

            for (int i = 0; i < listOne.Count; i++)
            {
                Console.Write(" " + listOne[i]);
            }

            Console.Write("\nIist 2 ->");

            for (int i = 0; i < listTwo.Count; i++)
            {
                Console.Write(" " + listTwo[i]);
            }

            Console.Write("\nIist 3 ->");

            for (int i = 0; i < listThree.Count; i++)
            {
                Console.Write(" " + listThree[i]);
            }
        }
    }
}
