MessageLevel

MessageLevel describes message severity.

/// <summary>Message severity level.</summary>
/// <remarks>Cast compatible with Microsoft.Extensions.Logging.LogLevel.</remarks>
public enum MessageLevel
{
    /// <summary>Detailed message. May contain sensitive application data.</summary>
    Trace,
    /// <summary>Message for development investigation.</summary>
    Debug,
    /// <summary>Application flow information.</summary>
    Information,
    /// <summary>Abnormal and unexpected events.</summary>
    Warning,
    /// <summary>Error in flow, but not application failure.</summary>
    Error,
    /// <summary>Application failure or crash.</summary>
    Critical,
    /// <summary>No logging.</summary>
    None
}

MessageLevel is castable to and from Microsoft.Extensions.Logging.LogLevel.

// MessageLevel -> LogLevel
Microsoft.Extensions.Logging.LogLevel logLevel = (LogLevel)(int)MessageLevel.Critical;
// LogLevel -> MessageLevel
MessageLevel messageLevel = (MessageLevel)(int)Microsoft.Extensions.Logging.LogLevel.Critical;

.SetSeverity(messagelevel) assigns message level to message description.

IMessageDescription bad = 
    new MessageDescription("MyLibrary.Bad", 0x0AC40000 | StatusCodes.Bad, "'{object}': Bad")
    .SetSeverity(MessageLevel.Error)
    .SetReadOnly();

.SetSeverity(messagelevel) assigns overriding message level to message.

IMessageDescription bad =
    new MessageDescription("MyLibrary.Bad", 0x0AC40000 | StatusCodes.Bad, "'{object}': Bad")
    .SetSeverity(MessageLevel.Error);

// Change message level
IMessage message = bad.New().SetSeverity(MessageLevel.Critical);

.SetSeverity(loglevel) assigns .Severity as LogLevel (Avalanche.Message.Logging.dll).

IMessageDescription bad =
    new MessageDescription("MyLibrary.Bad", 0x0AC40000 | StatusCodes.Bad, "'{object}': Bad")
    .SetSeverity(LogLevel.Error);

.SetSeverity(loglevel) assigns as LogLevel to message description (Avalanche.Message.Logging.dll).

IMessageDescription bad =
    new MessageDescription("MyLibrary.Bad", 0x0AC40000 | StatusCodes.Bad, "'{object}': Bad")
    .SetSeverity(LogLevel.Error)
    .SetReadOnly();

// Change message level
IMessage message = bad.New().SetSeverity(LogLevel.Error);
