Loading data from excel in C#

Hello Friends
I want to develop codes in C#. I have an excel file consist of ten rows and three column. I have to develop Random number and I will multiply that random numbers with the each row in excel file.
So, In order to do this:
How I will call excel file and access to the each row and column and then multiply with the random numbers.
To explain this more consider
C = ax + by +z:
where (a, b) are the random numbers (this is also an array of 100 rows and 2 column) generated in the C# and x, y, z is the experimental data saved in excel file. I have to access to the excel file and multiply the first row (a, b) with the first row in excel (x, y , z) to calculate C and similarly through all rows using for or while loop in C#.
How to program this code.
I expect full co-operation from you all.
Thank you very much
Ilyas

Edit:
Hello Thanks I have generated Random Like in the codes below

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 

namespace RandomNumber 
{ 

    class Program 
    { 
          static void Main(string[] args) 
          { 
             Double[,] randdouble = new Double[100, 2]; 
             Random randNum = new Random(); 

             for (int row = 0; row < randdouble.GetLength(0); row++) 
             { 
                   for (int col = 0; col < randdouble.GetLength(1); col++) 
                   { 
                        Double x = randNum.NextDouble(); 
                        randdouble[row, col] = x; 
                        Console.Write(randdouble[row, col]); 
                        Console.Write(" ");
                   } 
                   Console.WriteLine(); 
             } 
          } 
    } 
}

But how to proceed next is the main hurdle in my codes development. Thanks
