get the values in to the array 

now pull that array values in one Dataset haveing same 
array structure

now assign that dataset to the grid view

thats it

int[] arr = { 1, 2, 3, 4, 5, 6, 7, 8  };
        GridView1.DataSource = arr;
        GridView1.DataBind();

try this.

Dim i As Integer
        Dim fib(10) As Integer

        fib(0) = 1
        fib(1) = 1

        For i = 2 To 10
            fib(i) = fib(i - 1) + fib(i - 2)
        Next

        Me.grdResults.DataSource = fib
        Me.grdResults.DataBind()

all the answers are correct, but its not write way to store 
array to grid,if u insert data into grid view as the above 
mension answers expect first one answer, the data will be 
diaplayed in column wise, actually the data in grid view is 
displayed in rowwise, so we convert array data into a 
spesfic datasource like lists,generic list etc;


int32[] arr=new int32[10];
arr[1]=2;
arr[2]=3;

list<> lt=new list<arr>
lt.add(arr[1]);
lt.add(arr[2]);
 GridView1.DataSource = lt;
        GridView1.DataBind();
