Question

我试图将新项目添加到解决方案中，当我将引用添加到主项目时，它向我显示此错误：

Error   CS0570  'Logger.Debug(LogSource, string, params ?)' is not supported by the language

（以下代码中的“信息”和“警告”部分也会显示此错误）

这是此错误的代码部分（在新项目中引用了旧错误）：

namespace Logger
{
    class Program
    {
        static void Main(string[] args)
        {
            ConsoleLogger clogger = new ConsoleLogger();

            FileLogger<LockedLogWriter> errorLogger = new FileLogger<LockedLogWriter>(
                CsvLogFormatter.Instance,
                new PrivacyScrubber(PhoneNumberScrubber.Instance, IDScrubber.Instance, FullNameScrubber.Instance),
                new IncrementalLogFileName(@"c:\log", "a13_error", CsvLogFormatter.Instance.FileExtention),
                LogLevels.ErrorOnly,
                LogSources.All,
                true);

            FileLogger<LockedLogWriter> allLogger = new FileLogger<LockedLogWriter>(
                CsvLogFormatter.Instance,
                new PrivacyScrubber(PhoneNumberScrubber.Instance, IDScrubber.Instance, FullNameScrubber.Instance),
                new IncrementalLogFileName(@"c:\log", "a13_all", CsvLogFormatter.Instance.FileExtention),
                LogLevels.All,
                LogSources.All,
                true);

            //esm,shomare melli hazf
             FileLogger<LockedLogWriter> PhoneLogger = new FileLogger<LockedLogWriter>(
                CsvLogFormatter.Instance,
                new PrivacyScrubber(IDScrubber.Instance, FullNameScrubber.Instance),
                new IncrementalLogFileName(@"c:\log", "a13_EShazf", CsvLogFormatter.Instance.FileExtention),
                LogLevels.All,
                LogSources.All,
                true);

            //Client
            FileLogger<LockedLogWriter> ClientLogger = new FileLogger<LockedLogWriter>(
                CsvLogFormatter.Instance,
                new PrivacyScrubber(PhoneNumberScrubber.Instance, IDScrubber.Instance, FullNameScrubber.Instance),
                new IncrementalLogFileName(@"c:\log", "a13_Client", CsvLogFormatter.Instance.FileExtention),
                LogLevels.All,
                LogSources.Create(LogSource.Client),
                true);

            FileLogger<LockedLogWriter> uiLogger = new FileLogger<LockedLogWriter>(
                CsvLogFormatter.Instance,
                new PrivacyScrubber(PhoneNumberScrubber.Instance, IDScrubber.Instance, FullNameScrubber.Instance),
                new IncrementalLogFileName(@"c:\log", "a13_ui", CsvLogFormatter.Instance.FileExtention),
                LogLevels.All,
                LogSources.Create(LogSource.UI),
                true);


            Logger.Loggers.Add(errorLogger);
            Logger.Loggers.Add(allLogger);
            Logger.Loggers.Add(clogger);
            Logger.Loggers.Add(uiLogger);
            Logger.Loggers.Add(PhoneLogger);
            Logger.Loggers.Add(ClientLogger);

            // Logger is set up and ready to use

            Logger.Instance.Debug(LogSource.UI, "Login button clicked");
            Logger.Instance.Debug(LogSource.Client, "User logged in", ("Name", "Mr. Ali Hassan"));
            Logger.Instance.Debug(LogSource.UI, "Add phone number cliecked");
            Logger.Instance.Info(LogSource.Client, "User number added", ("Name", "Mr. Ali Hassan"), ("PhoneNumber", "+98 21 2543331"));
            Logger.Instance.Debug(LogSource.UI, "Add national ID cliecked");
            Logger.Instance.Warn(LogSource.Client, "User national ID added", ("ID", "232-12-1212"));
            Logger.Instance.Debug(LogSource.UI, "Display error to user");
            Logger.Instance.Error(LogSource.Client, "Unable to add user", ("ID", "232-12-1212"));
        }

        private static void Debug_onlog(LogEntry entry)
        {
            throw new NotImplementedException();
        }
    }
}

而且我已经安装了该System.ValueTuple软件包

这需要另一个包裹吗？

好像您要添加对在函数中使用params argument的程序集的引用。但是从不支持它的旧.NET Framework进行操作。您应该考虑在项目中使用更新的.NET Framework版本

C＃错误“语言不支持” CS0570
