HowTo code C# to read an Excel File

I am running local VS Express 2013 on Win7:64bit leveraging MSExcel 14.0 Object Library Interop Library added to Solution Reference.

I am only finding conflicting code for RAZOR shorthand for my .aspx.cs file
I am trying to code the following procedural loop to step through reading an adjacent excel file.

please help me identify why my worksheet object hints at missing some form of casting (Im too n00b)

thanks

using System.Data.OleDb;
using Excel = Microsoft.Office.Interop.Excel;

public partial class CMS_Application : System.Web.UI.Page{
    protected void Page_Load(object sender, EventArgs e){

       [i] // \/ Here is my code Im trying to create an Excel application here in C# for a web.ui .page:[/i]
        Excel.Application xlApp = new Excel.Application();
        [i]// \/ create the workbook [ container ][/i]
        Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\\ASP_OLEDB_NET\\cms.xls");
        [i]// \/ create the worksheet [/i]
        Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];

      [i]  // \/ Selected the range that was used [/i]
        Excel.Range xlRange = xlWorksheet.UsedRange;

        [i]// \/ Create two integers to contain the count of Columns and Rows. [/i]
        int rowCount = xlRange.Rows.Count;
        int colCount = xlRange.Columns.Count;

        // RAZOR simple programming syntax embedding server code in web pages 
        // statement blocks for RAZOR seem to not work at all . confused by its implementation
        //@{ var myMessage = "Hello World"; } // ERRORS out 'String expected after verbatim specifier'

       // \/ C# Forloop over the entire data set get values
        for (int i=1; i <=rowCount; i++) {
            // testing w/ concole write line
            Console.WriteLine(i);
                for(int j=1; j <= colCount; j++){
                    Response.Write(xlRange.Cells[i,j].Value2.ToString());
                    // /\ Not sure how to write syntax for above line
                }
        }
    }// end Page_Load
}// end class
