如何處理上傳中的「System.OutOfMemoryException」？

我對它們加密後上傳在本地驅動器上的文件和我在web.config中最大上傳限制爲如何處理上傳中的「System.OutOfMemoryException」？

<httpRuntime maxRequestLength="2147483647" executionTimeout="1000"/>

當文件大小爲greator然後20MB以下異常顯示

Source Error: 
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception 

Stack Trace:

看起來像你試圖讓你的文件在ViewState中，併發回客戶端..？ – Lanorkin 2013-04-04 10:49:53

我在上傳期間保存文檔字節在viewstate。對記憶有任何影響。 – mck 2013-04-04 10:52:51

你不應該在ViewState中存儲文件。它會對性能造成非常不利的影響（因爲它會在每個後續請求中傳輸兩次）

您需要將文件存儲在臨時文件夾中，然後將文件路徑存儲在ViewState中，請記住您需要某種排序的清理例程，刪除（例如）一天的文件
