This question is from the Forum. The original question is how to achieve win + L. The first reaction is to simulate the buttons. In fact, developers should not use this idea when they come up. If they cannot, they should consider pressing the buttons.
The solution code is as follows:
Using
System;
Namespace
Leleapplication2
...
{
Class
Program
...
{
Static
Void
Main (
String
[] ARGs)
...
{
System. Diagnostics. PROCESS p
=
New
System. Diagnostics. Process ();
P. startinfo. workingdirectory
=
System. environment. getfolderpath (environment. specialfolder. system );
P. startinfo. filename
=
"
Rundll32.exe
"
;
P. startinfo. Arguments
=
"
User32.dll, lockworkstation
"
;
P. Start ();
}
}
}
