    Open Method (DynamicsConnection)
    In This Topic
    Opens a Dynamics CRM connection with the property settings specified by the ConnectionString.
    Syntax
    'Declaration
     
    Public Overrides Sub Open() 
    public override void Open()
    Remarks
    The DynamicsConnection 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 DynamicsConnection 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 DynamicsConnection, opens it, displays some of its properties, and then closes the connection.
    public void CreateDynamicsConnection(string myConnString)
    {
      DynamicsConnection dynamicsConnection = new DynamicsConnection(myConnString);
      dynamicsConnection.Open();
      MessageBox.Show("ServerVersion: " + dynamicsConnection.ServerVersion
        + "\nState: " + dynamicsConnection.State.ToString());
      dynamicsConnection.Close();
    }
    Public Sub CreateDynamicsConnection(myConnString As String)
      Dim dynamicsConnection As New DynamicsConnection(myConnString)
      dynamicsConnection.Open()
      MessageBox.Show("ServerVersion: " + dynamicsConnection.ServerVersion _
        + ControlChars.Cr + "State: " + dynamicsConnection.State.ToString())
      dynamicsConnection.Close()
    End Sub
