Opens a Adobe Commerce connection with the property settings specified by the ConnectionString.

Syntax

Visual Basic

public override void Open()

'Declaration
 
Public Overrides NotOverridable Sub Open()

Remarks

The MagentoConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the data source.

Note: If the MagentoConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Devart.Common.DbConnectionBase.Close.

Opening an open connection does nothing.

Example

The following example creates a MagentoConnection, opens it, displays some of its properties, and then closes the connection.

csharp

public void CreateMagentoConnection(string myConnString)
{
  MagentoConnection adobe commerceConnection = new MagentoConnection(myConnString);
  adobe commerceConnection.Open();
  MessageBox.Show("ServerVersion: " + adobe commerceConnection.ServerVersion
    + "\nState: " + adobe commerceConnection.State.ToString());
  adobe commerceConnection.Close();
}

Visual Basic

Public Sub CreateMagentoConnection(myConnString As String)
  Dim adobe commerceConnection As New MagentoConnection(myConnString)
  adobe commerceConnection.Open()
  MessageBox.Show("ServerVersion: " + adobe commerceConnection.ServerVersion _
    + ControlChars.Cr + "State: " + adobe commerceConnection.State.ToString())
  adobe commerceConnection.Close()
End Sub
