Question

I have VS2010, Windows 7 bits, FxCop 10.0

I execute Fxcopcmd.exe using Process.Start, and I get 513 “exitcode” (error code) value.

Todd King in below reference says:

In this case an exit code of 513 means FxCop had an Analysis Error
(0x01) and an assembly references error (0x200)

I think if it is like

    [Flags]
    public enum FxCopErrorCodes
    {
        NoErrors = 0x0,
        AnalysisError = 0x1,  // -fatalerror
        RuleExceptions = 0x2,
        ProjectLoadError = 0x4,
        AssemblyLoadError = 0x8,
        RuleLibraryLoadError = 0x10,
        ImportReportLoadError = 0x20,
        OutputError = 0x40,
        CommandlineSwitchError = 0x80,
        InitializationError = 0x100,
        AssemblyReferencesError = 0x200,
        BuildBreakingMessage = 0x400,
        UnknownError = 0x1000000,
    }

513 integer value is 0x201 (view int to hex string and Enum.Parse fails to cast string )

How can I know errors (Analysis Error (0x01) and an assembly references error (0x200)) programmatically using only exitcode (513 , 0x201) value ?

You can test for a specific value of your enum using a AND bitwise operation:

FxCopErrorCodes code = (FxCopErrorCodes)0x201;
if ((code & FxCopErrorCodes.InitializationError) == FxCopErrorCodes.InitializationError)
{
    Console.WriteLine("InitializationError");
}

You could get the whole list of values using something like:

private static IEnumerable<FxCopErrorCodes> GetMatchingValues(FxCopErrorCodes enumValue)
{
    // Special case for 0, as it always match using the bitwise AND operation
    if (enumValue == 0)
    {
        yield return FxCopErrorCodes.NoErrors;
    }

    // Gets list of possible values for the enum
    var values = Enum.GetValues(typeof(FxCopErrorCodes)).Cast<FxCopErrorCodes>();

    // Iterates over values and return those that match
    foreach (var value in values)
    {
        if (value > 0 && (enumValue & value) == value)
        {
            yield return value;
        }
    }
}
