It doesn't do any harm to delete a non-existing event handler. So if you know what handlers there might be, you can simply delete all of them. I just had similar case. This may help in some cases.

Like:

// Add handlers...
if (something)
{
    c.Click += DoesSomething;
}
else
{
    c.Click += DoesSomethingElse;
}

// Remove handlers...
c.Click -= DoesSomething;
c.Click -= DoesSomethingElse;
