I have the following code:
private static LogLevel? _logLevel = null;
public static LogLevel LogLevel
{
get
{
if (!_logLevel.HasValue)
{
_logLevel = readLogLevelFromFile();
}
return _logLevel.Value;
}
}
private static LogLevel readLogLevelFromFile() { ... }
I get a ReSharper warning on the return
statement about a possible System.InvalidOperationException
and it suggests I check _logLevel
to see if it is null
first. However, readLogLevelFromFile
returns LogLevel
, not LogLevel?
, so there is no way the return
statement could be reached when _logLevel
is null
. Is this just an oversight by ReSharper, or am I missing something?
