System.Threading.Timer仅触发一次 [英] System.Threading.Timer only fires once

问题描述

使用下面的代码，计时器仅触发一次.我想念什么?

Using the code below, the timer only fires once. What am I missing?

public static List<string> Test = new List<string> { "TEST1", "TEST2" };

public static void Start()
{
    var t = new System.Threading.Timer(o =>
    {
        foreach (var item in Test)
        {
            Console.WriteLine("Say hello!"); 
        }
    }, null, 0, 1250);
}

推荐答案

GC在再次触发之前正在收集计时器.
您需要通过将其存储在字段中来保持活动状态.

The timer is being collected by the GC before it fires again.
You need to keep it alive by storing it in a field.
