tring运行gradle build时出现此错误

我理解它的版本冲突,但不知道如何解决它和哪些

要排除的版本...

gradle依赖树是:

SLF4J: Class path contains multiple SLF4J bindings.

当我的类包含套接字和事件时,如何实现Dispose模式？

它应该是这样的吗？

class MyClass
{
   Socket m_ListenerSocket = new Socket();
   book m_Disposed=false;

   public void Dispose()
   {
      Dispose(true);
      GC.SuppressFinalize(this);
   }

   private void Dispose(bool isDisposing)
   {
      if (!m_Disposed)
      {
          if (isDisposing)
          {
              if (m_ListenerSocket != null)
              {
                   m_ListenerSocket.Dispose();
                   innerClass.Notify -= Notify;
              }
          }
        //finalized unmanged code here
        m_Disposed = true;
      }
  }

  ~MyClass()
  {
       Dispose(false);
  }
}

我很困惑...套接字类是"托管代码c#版本的winSock"？因此,如果用户名为dispose("isDisposing IS为true"),它应该被释放,那么事件处理程序呢？

所以在最终评论部分应该只释放Inptr对象？谢谢.

我在一本书中看到了这个单身人士的推荐(部分代码附件):

public static Singleton GetSingleton() 
{
    if (s_value != null) 
        return s_value;
    Monitor.Enter(s_lock); 
    if (s_value == null) 
    {
        Singleton temp = new Singleton();
        Interlocked.Exchange(ref s_value, temp);
    }
    Monitor.Exit(s_lock);
    return s_value;
}

我们在第二个if语句块中添加两行代码,而不是只写:

s_value = new Singleton();

这应该处理第二个线程进入方法并查找s_value != null但未初始化的情况.

我的问题是,我们可以只在第二个if块写入:

{    
    Singleton temp = new Singleton();
    s_value = temp;  // instead of Interlocked.Exchange(ref s_value, temp);    
}

所以现在的功能是:

public static Singleton GetSingleton() 
{      
    if (s_value != null)
        return s_value;

    Monitor.Enter(s_lock);   
    if (s_value == null)   
    { 
        Singleton temp = new …

您能否举例说明如何使用 PowerShell 在出错时返回错误代码 1？

例如处理这种情况：

if ($serviceUserName) {
  cmd /c $serviceBinaryFinalPath install -username:$serviceUserName -password:$serviceUserPassword -servicename:"$ServiceName" -displayname:"$serviceDisplayName" -description:"$serviceDescription"
} else {
  cmd /c $serviceBinaryFinalPath install --localsystem -servicename:"$ServiceName" -displayname:"$serviceDisplayName" -description:"$serviceDescription"
}
