.NET異常錯誤，這個錯誤是什麼意思？

Question

我試過開發​​一個使用xml文件作爲數據庫的簡單winform工具。我已經使用VS 2008快速版，C＃。

當此實用程​​序嘗試寫入xml文件時，此錯誤顯示在其他計算機上。我試圖在另一臺計算機上的同一文件夾中提供System.Xml.dll & System.Xml.Linq.dll，但沒用。

這是什麼意思？任何解決方案

************** JIT Debugging ************** 
To enable just-in-time (JIT) debugging, the .config file for this 
application or computer (machine.config) must have the 
jitDebugging value set in the system.windows.forms section. 
The application must also be compiled with debugging 
enabled. 

For example: 

<configuration> 
    <system.windows.forms jitDebugging="true" /> 
</configuration> 

When JIT debugging is enabled, any unhandled exception 
will be sent to the JIT debugger registered on the computer 
rather than be handled by this dialog box. 

Answer 1

不提供System.Xml.dll & System.Xml.Linq.dll。它們是框架的一部分，應該已經存在於GAC中。確保用戶計算機上安裝了.NET 3.5 SP1。

Answer 2

這聽起來像你正在開發針對.NET 3.5，但隨後部署到只有.NET 2.0的機器。這是行不通的。

Answer 3

形式在這裏：Facebook Toolkit 2.0 - Error when running it on a server with asp.net 2.0 installed

也許你有你的目標機器上的錯誤.NET版本？

Answer 4

在異常轉儲中發生了非常可怕的事情。調用堆棧清楚地表明它正在執行Linq代碼，GetXmlReaderSettings（）僅在.NET 3.5程序集System.Xml.Linq中可用。但程序集列表不顯示此程序集。

事實上，該列表看起來已損壞，請注意名爲「4u_pgrmq」的條目。已從之前列出的System.dll加載。

.NET修訂號很低，832應該在.NET 3.0時間範圍內。可能的證據表明您已將3.5程序集添加到較早安裝的版本。

通過簡單地在機器上安裝.NET 3.5 SP1解決此問題的可能性應該不錯。
