First, start without syntax errors:

int[] array = new int[] { 3, 2, 1, 5, 4 };

Then you can use something like the LINQ OrderBy or OrderByDescending methods.

int[] array=new int[] {1,2,3,4,5};
for (int i=0;i>6;i++);
(int j=0;i;j>6-1;j++);

is this correct ??

No.

Arranging them and printing them are two different things.
...but that code will not do what you expect.
You need something more like:

for (int i = 0; i < array.Length; i++)
         {
            Console.Write(array[i]);
         }


         for (int j = array.Length; j > 0; j--)
         {
            Console.Write(array[j-1]);
         }

""""how i arrange numbers in ascending or descending order in array using c# software""""

C# is a programming langauge not a software. If you want to sort the array using C#, you have to do it using loop, I am not giving exact code but the here is the pseudo code:

Loop through all element of Array (outer loop)
Loop through all element of Array (inner loop)
compare outer loop element with inner loop element (greater than or less than according to asc or desc)

swap the element of arrays

end innerloop

end outer loop

         {
            Console.Write(array[j-1]);
         }

Use Console.WriteLine instead of Console.Write.

if i can run same program in windows form application then how we can done

[thines01]

Use a label to show the original array, then use a multi-line text box to show the result when a button is pushed.

i use windown form application...and in this i can use tabcontrol
in one tab the text box and save button and other tab there is a button which is RETRIEVE
and listbox ...
when i save numbers the in tab2 i click retrieve button to show numbers which i save it ...
and i want this numbers is decsending order...

i upload the picture but there is a problem in it...here is some coding

this is coding of form

namespace WindowsFormsApplication4
{

    public partial class Form1 : Form
    {
        add myadd = new add();
        public Form1()
        {
            InitializeComponent();
        }


        private void button2_Click(object sender, EventArgs e)
        {
            myadd.data(textBox1.Text);
            label1.Text = myadd.count.ToString();

        }

adn this coding of calss which i made

namespace WindowsFormsApplication4
{
    class add
    {
        string[] mydata = new string[10];
        int mpointer = 0;

        public int count
        {
            get
            {
                return mpointer;
            }
        }
        public void data(string input)
        {
            if (mpointer < mydata.Length)
            {
                mydata[mpointer] = input;
                mpointer++;
            }
            else
            {
                throw new Exception("not more sapce left");
            }
        }
        public string[] getdata()
        {
            return mydata;

then i dont understadn how i arrange these numbers in decending order :( :(
