使用VB.net进行多线程 [英] multi threading using VB.net

问题描述

我是多线程技术的新手.我的要求是从DB(Universe DB)中读取数据并创建报告并导出到excel.可能会创建多个报告，例如10到15个报告
在这里，我要做的是两个线程1)从DB读取报告数据2)使用每个数据创建excel
这些过程应作为后台过程.
请帮忙，任何实现此想法的想法都会受到赞赏.

在此先感谢.

推荐答案

这并没有什么意义:为什么要有两个线程这样做?为什么没有线程(来自 BackgroundWorker [

That doesn''t make a whole load of sense: why have two threads doing this? Why not have a thread (from the BackgroundWorker[^] pool) for each report? Then it keeps the related tasks together - each thread reads data, create report, export to excel, end thread.
Otherwise, you have to pass data between the threads, presumably using some form of queue - it''s much easier to handle if the thread handles the whole task, particularly as the next stage can''t start until the previous one is complete.
