public static bool TryInvoke(Action method)

Parameters

method Action

The delegate that to invoke.

Returns

bool

true if method was called without raising an exception; otherwise false.

Remarks

Actually an anti-pattern in regards to swallowing exception. That said, there are situations where this is a perfectly valid approach.
