Blazor服务器端计时器正在运行 [英] Blazor Server Side Timer is running amok

问题描述

我正在运行此ServerSide Blazor，并且有:

I have this ServerSide Blazor running and I have:

listTimer = new System.Timers.Timer();
        listTimer.Interval = 1000;
        listTimer.Elapsed += async (s, e) =>
        {
            await Utils.LogToConsole(jsRuntime, DateTime.Now.ToString());
        }

    `

但是，当我运行此程序时，我在Chrome控制台中会收到大量日志，但我希望每1000毫秒只能看到一次日志.任何人都看到此问题并找到了解决方法.是的，我可以检查实际时间并进行比较，但我不喜欢它触发那样的疯狂.

But when I run this I get huge amounts of log in the Chrome console but I expect to see only logs each 1000 millis. Anyone seen this problem and found a workaround. Yes I could check the actual time and compare but I dont like it triggering like thats crazy.

推荐答案

...我在Chrome控制台中收到大量日志

... I get huge amounts of log in the Chrome console

只有当您创建并分配了多个定时器时，这种情况才会发生.

That can only happen when you create and assign the Timer more than once.

您没有发布该代码，但我想您需要这样的内容:

You didn't post that code but I guess you need something like:

if (listTimer == null)
{
    listTimer = new System.Timers.Timer();
    listTimer.Interval = 1000;
    listTimer.Elapsed += async (s, e) =>
    {
        await Utils.LogToConsole(jsRuntime, DateTime.Now.ToString());
    }
}
