我遇到了連接到SQL Server實例的.net庫的問題。.net + SQL +超時問題
該庫是應用程序的一部分，它將edi文件的內容插入到SQL Server 2008 R2數據庫中。
每次調用該庫時，都會拋出一個異常（下面的＃1），指出連接超時。有問題的服務器上還有多個其他非.net應用程序，它們使用相同的連接字符串並且完美地工作。
我還在另一臺聯網的機器上安裝了包含該庫的應用程序，並且從那裏可以正常工作。
事情我曾嘗試：
設置.CommandTimeout = 150; - 在150秒前超時。
重新安裝所有.NET框架的內置
重新啓動應用服務器& DB服務器
從數據上下文標準數據適配器查詢開關。
創建一個獨立的EXE來測試使用數據上下文和標準數據適配器查詢連接字符串 - 兩種方法第一次失敗，但然後連接並讀取所有後續嘗試的數據，直到EXE重新啓動。這導致我添加一個重試嘗試延遲到庫中的異常時被擊中，但這會導致異常2.
我現在處於虧損狀態。任何幫助，將不勝感激。
