Why is the CommandLine property of a svchost.exe WIN32_Process null?

I try to silence system process that seem to go 100% sometimes with my program on; I don't mean to fix that system process but just to silence it. What I tried is:

ManagementObjectSearcher searcher = new ManagementObjectSearcher
( 'select CommandLine,ProcessId from Win32_Process where Name='svchost.exe'' );
ManagementObjectCollection retObjectCollection = searcher.Get( );
foreach( ManagementObject retObject in retObjectCollection )
if( ( ( string )retObject[ 'CommandLine' ] ).Contains( '-k NetworkService' ) ) { // <-- exception
var process = Process.GetProcessById( int.Parse( retObject[ 'ProcessId' ].ToString( ) ) );
process.PriorityClass = ProcessPriorityClass.Idle;
process.ProcessorAffinity = new IntPtr( 1 );
}
retObjectCollection.Dispose( );


This code seem to raise null-exception.

When I add retObject[ 'CommandLine' ] != null && in the if's condition and debug it, all the values that produced from the expression retObject[ 'CommandLine' ] are just null.

Wwhen I change scvhost.exe to notepad.exe they produce non-null values.

Why is that and how I can fix it to fetch system processes' commandline?
