我将数据库包含到项目文件中并构建解决方案，当我在另一台机器上运行应用程序时出现错误

************** 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.

配置文件：

<?xml version="1.0"?>
<configuration>
    <configSections> </configSections>
    <connectionStrings>
        <add name="IstanbulFoodDBConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\IstanbulFood\POSApp\IstanbulFoodPOS\IstanbulFoodDB‌.mdbb;Persist Security Info=True" providerName="System.Data.OleDb"/>
    </connectionStrings>
    <configuration>
        <system.windows.forms jitDebugging="true"/>
    </configuration>
    <startup>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
</configuration>

Answer 1

你确定在另一台机器上的文件路径“D：\ IstanbulFood \ POSApp \ IstanbulFoodPOS \ IstanbulFoodDB .mdbb”是一样的吗？

Answer 2

看起来您遇到连接字符串问题。您可以在here中找到示例。

示例连接字符串应为;

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.accdb; Persist Security Info=False;

Answer 3

该异常是由于app.config文件中的其他配置元素造成的。尝试将<system.windows.forms jitDebugging="true"/>元素向上移动一层嵌套，例如：

<?xml version="1.0"?>
<configuration>
    <configSections> </configSections>
    <connectionStrings>
        <add name="IstanbulFoodDBConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\IstanbulFood\POSApp\IstanbulFoodPOS\IstanbulFoodDB‌.mdbb;Persist Security Info=True" providerName="System.Data.OleDb"/>
    </connectionStrings>

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

    <startup>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
</configuration>

Answer 4

我已将数据源更改为：

Data Source =|DataDirectory|\IstanbulFoodDB.mdb;

当我在另一台机器上运行应用程序时，它正在工作; 这也是Config文件：

<?xml version="1.0"?>
<configuration>
  <configSections> </configSections>
  <connectionStrings>
    <add name="IstanbulFoodDBConnectionString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\IstanbulFoodDB.mdb;Persist Security Info=False;" providerName="System.Data.OleDb"/>
  </connectionStrings>

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

  <startup>
    <supportedRuntime version="v2.0.50727"/>
  </startup>
</configuration>

我需要将.mdb数据库附加到C＃桌面应用程序
