示例1: CreateReader
public void CreateReader(string connectionString, string queryString)
{
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
OleDbCommand command = new OleDbCommand(queryString, connection);
connection.Open();
OleDbDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(reader[0].ToString());
}
reader.Close();
}
}示例2: CreateMyOleDbDataReader
public void CreateMyOleDbDataReader(string queryString,string connectionString)
{
OleDbConnection connection = new OleDbConnection(connectionString);
OleDbCommand command = new OleDbCommand(queryString, connection);
connection.Open();
OleDbDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
while(reader.Read())
{
Console.WriteLine(reader.GetString(0));
}
reader.Close();
//Implicitly closes the connection because CommandBehavior.CloseConnection was specified.
}示例3: Main
