Methods to dispose of SQL Server CE, SQL Server 2005 Compact Edition, or SQL Server 2005 Mobile Edition managed objects from memory

 SqlCeConnection conn = null; 
 try
 {
	 conn = new SqlCeConnection(<ConnectionString>);
	 conn.Open(); 
	// Work with the connection object
}
catch (Exception en)
{
	// Handle the exception or rethrow it
}
finally
{
	// Always release the native references in the finally clause
	// The statements in finally clause are guaranteed to run

	if (null != conn) conn.Close(); 
} 

try
{
	SqlCeConnection conn = null;
	conn = new SqlCeConnection(<ConnectionString>);
	conn.Open(); 

	// The connection instance goes out of scope and effectively loses native references here
	// The conn object is only disposed of when the Garbage Collector starts finalizing objects,
	// but this only occurs under memory pressure.
	// If many objects are allocated like this, the performance of the program decreases.
}
catch (Exception en)
{
	// Handle the exception or rethrow it
} 
	// If GC.Collect() is called, the Garbage Collector is forced to run all the finalizers in the finalization queue. 
	//Therefore, the connection instance that was previously lost is disposed of here by the Collect method of the GC Garbage Collector class. 
	
GC.Collect();
