Question

What’s the simplest way to connect and query a database for a set of records in C#?

Answer 1

@Goyuix — that’s excellent for something written from memory. tested it here — found the connection wasn’t opened. Otherwise very nice.

using System.Data.OleDb; ...  using (OleDbConnection conn = new OleDbConnection()) {     conn.ConnectionString = 'Provider=sqloledb;Data Source=yourServername\\yourInstance;Initial Catalog=databaseName;Integrated Security=SSPI;';      using (OleDbCommand cmd = new OleDbCommand())     {         conn.Open();         cmd.Connection = conn;         cmd.CommandText = 'Select * from yourTable';          using (OleDbDataReader dr = cmd.ExecuteReader())         {             while (dr.Read())             {                 Console.WriteLine(dr['columnName']);             }         }     } }
