IDbCommandInterceptor查询监控

Question

我在EF6中创建了一个查询拦截器：

public class QueryCommandInterceptor : IDbCommandInterceptor
{
    private readonly Stopwatch _stopWatch = new Stopwatch();

    public void NonQueryExecuting(DbCommand command, DbCommandInterceptionContext<int> interceptionContext)
        {
            _stopWatch.Restart();
        }

        public void NonQueryExecuted(DbCommand command, DbCommandInterceptionContext<int> interceptionContext)
        {
            _stopWatch.Stop();
        }
}

两个Executing方法可以在相应的Executed方法完成之前启动吗？

你的意思是，这个IDbCommandInterceptor线程安全吗？
