Query Microsoft Access MDB Database using LINQ and C#

Im working with MS access database and wanted to know if i could use LINQ to query this database? I read about datasets, but by reading this: http://blogs.msdn.com/b/adonet/archive/2007/01/26/querying-datasets-introduction-to-linq-to-dataset.aspx
i see that not much of a database can be accesed through datasets. Can anyone help me as to how i could go bout this? Thanks 🙂

Unfortunately LINQ does not support access database. As work around you could use Ado.net DataSet to pull out the data from your database

//create the connection string
string connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\myDatabase.mdb";

//create the database query
string query = "SELECT * FROM MyTable";

//create an OleDbDataAdapter to execute the query
OleDbDataAdapter dAdapter = new OleDbDataAdapter(query, connString);

//create a command builder
OleDbCommandBuilder cBuilder = new OleDbCommandBuilder(dAdapter);

//create a DataTable to hold the query results
DataTable dTable = new DataTable();

//fill the DataTable
dAdapter.Fill(dTable);

Then you can use LINQ to object to do your query (even if I won’t recommend you to use this approach because of the performance are not very good)

var results = from myRow in dTable.AsEnumerable()
where myRow.Field<int>("RowNo") == 1
select myRow;
