Creating Win32 events from c#

Question

I\'d like create a kernel(aka named events) from C#.

Do I have to interop services and wrap the native CreateEvent function or is there already a .NET class that does t

Answer 1

Take a look at the EventWaitHandle class. It's supported from .Net 2.0 onwards and allows creation of named events. It also supports setting event security, depending on which constructor you use.

Answer 2

If you still want to use interop, you can define the function like this:

[DllImport("kernel32.dll")]
static extern IntPtr CreateEvent(IntPtr lpEventAttributes, bool bManualReset, bool bInitialState, string lpName);

and the struct like this(you may have to mess with the Pack attribute to make it fit):

[StructLayout(LayoutKind.Sequential)]
struct SECURITY_ATTRIBUTES{
  public int length;
  public IntPtr securityDesc;
  public bool inherit;
}

Also, here's a code example of putting it all together.
