我为Unity编译了一个.dll，其中包含多个组件。 其中之一是记录器，它会写入文件。但是为了在Unity中进行调试，我想添加一个将Log重定向到Function的委托。此功能在Unity中分配。但是，即使分配正确，也可以在dll端取消分配委托。 我想知道这是否与C＃7.2与Mono 4.5有关。
无论如何，这是dll的代码。

private static LoggerCallback onLogEvent;
/// <summary>

{
writeLock.WaitOne();
//If the logger is open already, do nothing
if (IsInit)
{
}
else
{
isInit = true;
location = path;
debugLevel = dLevel;
if (Directory.Exists(location))
{

{
File.Create(location + fileName);
}
catch (IOException ioE)
{
}
}
}
else
{
Directory.CreateDirectory(location);
File.Create(location + fileName);
}
}
writeLock.ReleaseMutex();
Log("Log Session opened at" + location + fileName);
}

public static void LogRaw(byte[] log, DebugLevel level = DebugLevel.Info)
{
//Debuglevel is lower than required for printing
if (level > debugLevel)
{
}
else
{
using (StreamWriter sWriter = new StreamWriter(location + fileName, true))
{
sWriter.WriteLine("[" + level.ToString() + "]" + log + " | " + DateTime.Now.ToLongTimeString());
}
if (OnLogEvent != null)
{
OnLogEvent?.Invoke("[" + level.ToString() + "]" + log + " | " + DateTime.Now.ToLongTimeString());
ShatNetLogger.Log("Calling " + OnLogEvent.Method.Name);
}
else
{
}
}
}
这是Unity部分，作用不大。
public void Start()
{
ShatNetNetwork.StartListenServer();
ShatNetLogger.OnLogEvent += Log;
}
void Update()
{
}
void OnApplicationQuit()
{
ShatNetNetwork.Close();
Debug.Log("API Shutdown");
}
public void Log(string log)
{
Debug.Log(log);
}
