Note: If the SqlConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Close.
Opening an open connection does nothing.
public void CreateSqlConnection(string myConnString) { SqlConnection myConnection = new SqlConnection(myConnString); myConnection.Open(); MessageBox.Show("ServerVersion: " + myConnection.ServerVersion + "\nState: " + myConnection.State.ToString()); myConnection.Close(); }
Public Sub CreateSqlConnection(myConnString As String) Dim myConnection As New SqlConnection(myConnString) myConnection.Open() MessageBox.Show("ServerVersion: " + myConnection.ServerVersion _ + ControlChars.Cr + "State: " + myConnection.State.ToString()) myConnection.Close() End Sub
