RFmx provides the following methods to close a session.

public void Dispose() public void Close() public void ForceClose()

The Dispose and Close methods perform a reference counted close.

The following snippets show an example of closing a session using the Close method.

C#

//ref count is 0 RFmxInstrMX InstrSession1 = RFmxInstrMX.GetSession("Rfsa",""); 
RFmxInstrMX InstrSession2 = RFmxInstrMX.GetSession("Rfsa",""); 
RFmxInstrMX InstrSession3 = RFmxInstrMX.GetSession("Rfsa",""); //ref count is 3
InstrSession1.Close(); //ref count is 2. Session is not disposed yet. 
InstrSession2.Close(); InstrSession3.Close(); //Session is closed when ref count hits 0.

VB

'ref count is 0 Dim InstrSession1 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 
Dim InstrSession2 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 
Dim InstrSession3 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 'ref count is 3
InstrSession1.Close() 'ref count is 2. Session is not disposed yet. 
InstrSession2.Close() 
InstrSession3.Close() 'Session is closed when ref count hits 0.

The ForceClose method closes a session irrespective of the reference count. The following snippets show an example of closing a session using the ForceClose method.

C#

 //ref count is 0 RFmxInstrMX InstrSession1 = RFmxInstrMX.GetSession("Rfsa",""); 
RFmxInstrMX InstrSession2 = RFmxInstrMX.GetSession("Rfsa",""); 
RFmxInstrMX InstrSession3 = RFmxInstrMX.GetSession("Rfsa",""); //ref count is 3
InstrSession1.ForceClose(); //Session is closed irrespective of reference count.

VB

'ref count is 0 Dim InstrSession1 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 
Dim InstrSession2 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 
Dim InstrSession3 As RFmxInstrMX = RFmxInstrMX.GetSession("Rfsa", "") 'ref count is 3
InstrSession1.ForceClose() 'Session is closed irrespective of reference count.
