C# 大數(shù)據(jù)導(dǎo)出word的假死報(bào)錯(cuò)的處理方法
最近一個(gè)項(xiàng)目是一個(gè)基于winform的報(bào)告系統(tǒng)，根據(jù)一系列的查詢參數(shù)計(jì)算出結(jié)果，最終生成一個(gè)格式規(guī)范的word文檔，剛開(kāi)始數(shù)據(jù)量不大（500行）數(shù)據(jù)以內(nèi)，寫(xiě)入速度還能接受，但最近遇到一個(gè)問(wèn)題就是當(dāng)出現(xiàn)大量的數(shù)據(jù)行的時(shí)候，寫(xiě)入word的過(guò)程就變的非常慢，CPU直接拉到100%，本人機(jī)器配置已經(jīng)算比較高的了，8G內(nèi)存+i5CPU，依舊假死，該問(wèn)題困擾了我?guī)滋?，也?wèn)了google很多次，基本上給出的答案都是word本身就比較慢這樣一類(lèi)的答案，或者是非托管代碼的優(yōu)化，慢也就算了，至少可以通過(guò)進(jìn)度條來(lái)交互，假死到報(bào)錯(cuò)，這個(gè)絕對(duì)是零容忍的。嘗試了很多種方法，包括將非托管代碼強(qiáng)制進(jìn)行回收，多線程等方式，最終都失敗了，當(dāng)然，黃天不負(fù)有心人最終總算是解決了問(wèn)題了，我的數(shù)據(jù)量不算特別巨大，就4000多行寫(xiě)入表中，廢話少說(shuō)，直接貼代碼：

上面的代碼就是通過(guò)winwordControl控件加載word模板，一行一行向word表格中寫(xiě)入數(shù)據(jù)，新的表格通過(guò)書(shū)簽復(fù)制后粘貼，然后繼續(xù)一行一行的寫(xiě)入，數(shù)據(jù)量在500行以內(nèi)的時(shí)候，速度還是可以接受的，當(dāng)數(shù)據(jù)量增大之后，就很慢了
改進(jìn)后的代碼，主要用到了分頁(yè)的思想，將集合或者datatable進(jìn)行分頁(yè)，每頁(yè)處理50行數(shù)據(jù)，處理完了之后保存到臨時(shí)文件，釋放掉word資源，再打開(kāi)臨時(shí)文件，接著上次的寫(xiě)入位置繼續(xù)寫(xiě)入。釋放word資源就是為了解決寫(xiě)入數(shù)據(jù)量過(guò)大假死報(bào)錯(cuò)的問(wèn)題。希望對(duì)處理word的朋友有幫助
