You could do something like:

string[] sade = new string[6];
.
.
sade[5] = Registry.GetValue(@"HKEY_LOCAL_MACHINE\Software\secon\secservice",    "CurrentVersion", "0");
if(sade[5] == null)
{
Registry.SetValue(@"HKEY_LOCAL_MACHINE\Software\secon\secservice",    "CurrentVersion", "0");
}

That will read the registry and check if it is already defined or not.
