【问题描述】：

我已经使用 sqlite 数据库创建了一个应用程序并添加了 db 文件，当部署到其他计算机上时，安装程序仍然出现此异常。我认为数据集引起了问题。需要帮助！！

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

【问题讨论】：

你能从正确的端口 ping 数据库服务器并得到响应吗？
我使用了 sqlite 数据库，应用程序在我的电脑上运行良好，只要我将它安装到其他电脑上，它就会显示未找到的表名并显示数据，而在某些我需要获取的表单上数据库中的数据并删除一些它不显示任何数据，我已经使用数据集进行数据检索

标签： c# sqlite deployment installation dataset

【解决方案1】：

您的异常的第一行：

SQLite error no such table: Doctor

这意味着您忘记了表 Doctor 或者您连接到错误的数据库。检查您的连接字符串。

【讨论】：

我在调试文件夹中有我的 db 文件，它在我开发应用程序的电脑上运行良好
这是我在 app.config 文件中的连接字符串。 connectionString="data source="C:\Users\user\Desktop\Pathology lab\screen shot\bin\Debug\Pathorecord.db""
数据库是否在已部署系统的同一路径中？同样在安装时，您是在创建一个新的空数据库，还是在移动包含所有必要表的数据库？
我在进行设置时添加了相同的 db 文件。

【解决方案2】：

我在 VMware 中测试时遇到了类似的问题，这是因为在数据集设计器中删除/重新添加数据集后，它在 settings.settings 中的属性下创建了一个新的连接字符串，这是一个硬编码路径，旧的正确字符串与 |数据目录|它仍然存在但未使用。您可以将好的字符串复制到新字符串并删除未使用的字符串。很简单。
