指定的網路名稱無法使用。

'/2018' 應用程式中發生伺服器錯誤。

指定的網路名稱無法使用。

描述: 在執行目前 Web 要求的過程中發生未處理的例外狀況。請檢閱堆疊追蹤以取得錯誤的詳細資訊，以及在程式碼中產生的位置。

例外狀況詳細資訊: System.ComponentModel.Win32Exception: 指定的網路名稱無法使用。

原始程式錯誤:



只有在偵錯模式編譯時，才可以顯示產生此未處理例外狀況的原始程式碼。若要啟動，請依照下列步驟之一，然後要求 URL:

1. 將 "Debug=true" 指示詞加入產生錯誤的程式碼頂端。例如:

   <%@ Page Language="C#" Debug="true" %>

或:

2. 將下列區段加入您應用程式的組態檔:

<configuration>
    <system.web>
        <compilation debug="true"/>
    </system.web>
</configuration>

請注意: 第二種技巧會導致在偵錯模式下編譯指定應用程式中的所有檔案。第一種技巧只會造成在偵錯模式下編譯該特定檔案。

重要資訊: 在偵錯模式下執行應用程式會過度耗用記憶體/效能。在實際執行部署之前，應該先確認應用程式已經停止偵錯。
