这是错误，谁来帮忙解决下？Object synchronization method was called from an unsynchronized block of code

今天自己写一个简单的模拟线程池，遇到这样一个Object synchronization method was called from an unsynchronized block of code，解决不了，谁给解释一下？
下面是我的主要思路：

class concreteTask : task
{
public override void begin() //开始运行线程
{
try
{
threadmutex.ReleaseMutex();
}
catch (Exception e)
{
Console.WriteLine("线程调度失败！{0}", e.Message);
}
}
public override void run()
{
while (true)
{
threadmutex.WaitOne(); //等待新的调度进入
stat = true;
{
//TODO:在此提供具体的任务处理
}
stat = false;
// threadmutex.ReleaseMutex();
}
}
}
在线程池中我只要不断调用begin()就能取得一个线程执行一个任务

但在 threadmutex.ReleaseMutex()这一句总是出现 Object synchronization method was called from an unsynchronized block of code

同步方法用同步调用
异步方法异步调用

那加上LOCK可以吗？效果还是一样啊

刚刚把MUTEX换成mannualresetevent来实现，程序正常运行啦。。。实在不明白这是为什么
