Best Practice for Try Catch Error Handling

.net, exception

Solution

Do not catch the exception. Allow the exception to "bubble-up" to force the caller/callers to handle setting the default security value.

If you really want to return a value then use `Nullable<SecurityLevel>` or `SecurityLevel?`.

private SecurityLevel? ApiGetSecurityLevel() { 
    try { 
        return _BioidInstance.GetSecurityLevel(); 
    } 
    catch {  
        return null; 
    } 
}

Then use as:

if (ApiGetSecurityLevel().HasValue == false) {
    // use default security level
}

Problem

I'm trying to avoid returning an incorrect value when in the catch but I'm having trouble finding a better solution than this: ``` private SecurityLevel ApiGetSecurityLevel() { try { return _BioidInstance.GetSecurityLevel(); } catch { return SecurityLevel.High; } } ``` Is there a better way of doing this so I don't return incorrect values? I can't change the SecurityLevel enum.
