将配置添加到App.config文件时出错

问题描述

相关问题：

这是我的App.config文件的样子：

This is how my App.config file looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="DocumentsDBEntities" connectionString="metadata=res://*/Documents.csdl|res://*/Documents.ssdl|res://*/Documents.msl;provider=System.Data.SQLite;provider connection string=&quot;data source=C:\Users\Sergio.Tapia\Desktop\DocumentScannerDanyly\DocumentScannerDanyly\DocumentsDB.sqlite&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" />
  </startup>
  <appSettings>
    <add key="Username" value="administrador"/>
    <add key="Password" value="123456"/>
  </appSettings>
</configuration>

在我的开发机器上运行这个工具，但是当部署到另一台计算机时，我收到一个数据提供程序错误。 （见上面的相关问题）。

Running this on my dev machine works, but when deploying to another computer, I get an Data Provider error. (see related question above).

建议的解决方案是将其添加到App.config文件中：

The suggested solution was to add this to the App.config file:

<system.data>
        <DbProviderFactories>
                <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/>
        </DbProviderFactories>
</system.data>

当我将其添加到App.config文件中时，在Visual中启动应用程序时会收到此错误Studio 2010：

When I add that to the App.config file, I get this error when launching the application in Visual Studio 2010:

关于这个错误的任何建议？另外，由于.sqlite文件的位置与安装位置是否相关，所以我必须将AppConfig文件中的connectionString更改为更动态的？

Any suggestion on what this error is? Also, since the location of the .sqlite file is relative to where it is installed, do I have to change the connectionString in the AppConfig file to something more dynamic?

谢谢帮助。

编辑：

当我将其添加到配置根据某人的建议，我收到一个错误：

When I add this to the config as suggested by someone here, I get an error:

<system.data>
        <DbProviderFactories>
                <clear />
                <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/>
        </DbProviderFactories>
</system.data>

推荐答案

问题很可能是硬编码到桌面的路径在你的连接字符串中：

The problem is most likely that you hard code a path to your desktop in your connection string:

C:\Users\Sergio.Tapia\Desktop\DocumentScannerDanyly\DocumentScannerDanyly\DocumentsDB.sql

除非该文件与另一台机器上的完全相同的位置存在，否则有可能不能工作

Unless this file is present with the exact same location on the other machine, chances iare it won't work
