asp.net線程批量導(dǎo)入數(shù)據(jù)是大家日常工作中常遇到的一個(gè)要求，但批量添加時(shí)間一般較長(zhǎng)，如果能返回執(zhí)行的狀態(tài)就好，那么下面這篇文章主要給大家介紹了asp.net線程批量導(dǎo)入數(shù)據(jù)時(shí)通過(guò)ajax獲取執(zhí)行狀態(tài)的方法,有需要的朋友可以參考下。

前言

最近因?yàn)楣ぷ髦杏龅揭粋€(gè)需求，需要做了一個(gè)批量導(dǎo)入功能，但長(zhǎng)時(shí)間運(yùn)行沒(méi)個(gè)反饋狀態(tài)，很容易讓人看了心急，產(chǎn)生各種臆想！為了解決心里障礙，寫(xiě)了這么個(gè)功能。

通過(guò)線程執(zhí)行導(dǎo)入，并把正在執(zhí)行的狀態(tài)存入session，既共享執(zhí)行狀態(tài)，通過(guò)ajax調(diào)用session里的執(zhí)行狀態(tài)，從而實(shí)現(xiàn)反饋導(dǎo)入狀態(tài)的功能！
