Read from an Ecxwl Spreadsheet using c#

Question

Hi all, I am trying to read data from an excel spreadsheet using c#. My operating system is Windows XP Professional. I have Office 2003 installed on my system. I have added microsoft excel object 11.0 as reference to my c# project . But i get an error that the excel object is not recognised. Please help. The code looks like this. private Excel.Application ExcelObj = null; public Form1() { // Initialize the Windows Components InitializeComponent(); ExcelObj = new Excel.Application(); // See if the Excel Application Object was successfully constructed if (ExcelObj == null) { MessageBox.Show("ERROR: EXCEL couldn't be started!"); System.Windows.Forms.Application.Exit(); } // Make the Application Visible ExcelObj.Visible = true; }
