OdbcConnection::State Property
.NET Framework (current version)
Gets the current state of the connection.
Assembly: System.Data (in System.Data.dll)
public: [BrowsableAttribute(false)] property ConnectionState State { virtual ConnectionState get() override; }
Property Value
Type: System.Data::ConnectionStateA bitwise combination of the ConnectionState values. The default is Closed.
Implements
IDbConnection::StateThe following are allowed state changes:
From Closed to Open, using the Open method.
From Open to Closed, using either the Close or Dispose method.
 Note |
|---|
Calling the State property on an open connection increases application overhead because each such call causes a SQL_ATTR_CONNECTION_DEAD call to the underlying ODBC driver to determine whether the connection is still valid. |
