You have to get the "dotnet driver" of the database (or any

other datasource) you want to access to.

For example:

MySQL: Connector/Net

Access: Microsoft Access Driver

Oracle: Oracle Data Access Components (ODAC)

Afterwards you build a connection string to tell your

programm which driver you want to use and where the

datasource can be found, for example:

public const string DB_CONN_STRING =

"Driver={Microsoft Access Driver (*.mdb)}; "+

"DBQ=D:\CS\TestDbReadWrite\SimpleTest.mdb";

Afterwards you just have to open a connection to the

database using the previously created connection string and

send a query to the database to get the record:

ADOConnection conn = new ADOConnection(DB_CONN_STRING);

conn.Open();

ADODataReader dr;

ADOCommand cmd = new ADOCommand( "SELECT * FROM <table>",

conn );

cmd.Execute(out dr);

while (dr.Read()){

....}
