Thanks Reiner n Guangwei.

What is the difference with Connection and proxy?

I open the connection and dispose it later and Im still able to display data through the sapproxy.

I dont get it. I thought by disposing the connection, the sapproxy should not be working.

Anybody can explain it to me.

Thank you.

The connection maintains the connection state, while the proxy maintains the functional aspect. Indeed a proxy without an open connection wouldn't work:

Connection conn = Connection.GetConnection(myDestination);

conn.Open(); // This would throw if connection data in myDestination is bad


SAPProxy1 proxy = new SAPProxy1();

proxy.Connection = conn;


conn.Dispose(); // Closes connection

proxy.Method1(...); // Will fail

proxy.Connection = null;

proxy.Dispose(); // Doesn't have an effect here. It would also Dispose the assigned connection.
