OleDbConnection Constructor

Initializes a new instance of the OleDbConnection class.

Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

public OleDbConnection()

When a new instance of OleDbConnection is created, the read/write properties are set to the following initial values unless they are specifically set using their associated keywords in the ConnectionString property.

Properties

Initial value

ConnectionString

empty string ("")

ConnectionTimeout

15

Database

empty string ("")

DataSource

empty string ("")

You can change the value for these properties only by using the ConnectionString property.

The following example creates and opens an OleDbConnection.


static void OpenConnection(string connectionString)
{
    using (OleDbConnection connection = new OleDbConnection(connectionString))
    {
        try
        {
            connection.Open();
            Console.WriteLine("DataSource: {0} \nDatabase: {1}",
                connection.DataSource, connection.Database);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        // The connection is automatically closed when the
        // code exits the using block.
    }
}
