Sum Of series in c#.net source code with output and explanation

Sum Of series in c#.net source code with output and explanation
in this program we will see how to calculate sum of series till sum number like 10 , 20 , etc....
Now what we will do we will just take two value assign them as 0  and 1. so , at least we will get
some value at start.
In this article i have shown here how  to calculate sum of series in c# .net on Page Init
 event.


 protected void Page_Init(object sender, EventArgs e)
    {
       
     
       int a=0;   //here i have initialize two valus as 0 and 1.
        int b=1;
        int num=20;
        Response.Write("Sum Of series Before:"+num);
        Response.Write("</br>");
       int  sum=0;
        for (int j=1;j<=num;j++)
        {
            sum=a+b; //swappping.............
            a=b;
            b=sum;
            Response.Write(sum+"-");  // printing the values.......
        }

       
        }


OUTPUT
Sum Of series Before:20
1-2-3-5-8-13-21-34-55-89-144-233-377-610-987-1597-2584-4181-6765-10946  

IF YOU WILL TAKE NUM=10
THEN OUTPUT WILL

Sum Of series Before:10
1-2-3-5-8-13-21-34-55-89
