Retriving Data from MSAccess Database

Hello again Raghavendra :)
As stated in my previous answer to your question - you should seriously check these links - there you will find step by step guidance.
If that is not clear - check bellow:

//Csome sort of connection to MS Access DB (whether it is oleDb or PDBC)
//in this case lets use DBC
//depending on your MS Access version you might need to use different providers
//Microsoft.ACE.OLEDB.12.0, Microsoft.ACE.OLEDB.8.0 and etc.
string ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Data.accdb";
OleDbConnection oConnect = new OleDbConnection(ConnectionString);
oConnect.Open();
//now when connection is open we can do stuff with it:
string SQL_Command = "SELECT [SomeColumnName] FROM [SomeTableName]";
OleDbCommand oCommand = new OleDbCommand(SQL_Command, oConnect);
OleDbDataReader dReader = oCommand.ExecuteReader();
//now dReader has the stuff "eaten" so we can loop through it:
List<dynamic> myData = new List<dynamic>();
while (dReader.Read())
{
   myData.Add(dReader.GetValue(0));
}
oConnect.Close();
//now your variable myData will have all data taken from the MS Access DB and you can do something with... display somewhere or do LINQ stuff... or something else.</dynamic></dynamic>

Cheers!

Modestas.

P.S.: please read the links that I gave you before.
