What's wrong with this?

if (bool)(UserIDs[i] == ThisUserId)
{
return true;
}

There's a closing "}", it's inside a function.

if (bool)(UserIDs[i] == ThisUserId)
{
return true;
}

private bool validateUserId(string ThisUserId, string[] UserIDs)

if (bool)(UserIDs[i] == ThisUserId)
{
return true;
}

You are not converting types here. the result of the == is a bool not
a string. It looks like missing parentheses

The statement should be something along the lines of

if ( (bool)(UserIDs[i] == ThisUserID) ) {
return true;
....

Although there should be no need for the (bool)

if ( UserIDs[i] == ThisUserID) {
return true;
...

hth,
Alan.

there's no need for anything except return (UserIDs[i] == ThisUserID);

Sort of.

It's not clear from the original posting whether there was an altermate
action on if they didn't match ( there is no closing brace, so it
looks like a snippet rather than the whole routine.)

e.g

if ( UserIDs[i] == ThisUserID) {
return true;
}
else {
LogErrorMessage();
DoInterestingThings();
}

If the only thing that the routine does is check the validity of the
user ID and return true/false, then

return (UserIDs[i] == ThisUserID);

does suffice.

Alan.

I'm guessing you mean if((bool) (UserIDs[i] == ThisUserId)) but the
explicit cast is redundant. What are the types of the variables listed?
