c# - SQLite 的相对路径不适用于 WIX 工具集

Question

我正在使用 SQLite 数据库并使用 WIX 工具集创建 WPF 应用程序的安装程序。问题是，当我直接从 Visual Studio 运行时，下面的相对路径工作正常，但当我使用 WIX 创建安装程序时不起作用，并且在安装此安装程序运行程序后，它会给出数据库文件的 fatal error 。 在项目目录中，我创建了一个数据库文件夹，数据库文件位于其中，如下图所示:

通过WIX Toolset创建安装程序后，安装文件如下:

inventory_control.db 文件路径:

dbConnectionString 路径:

我已经为相对路径连接字符串编写如下代码:

相对路径:

  string relativePath = @"Database\inventory_control.db";
        string currentPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
        //string path = currentPath.Substring(0, currentPath.Length - 21);
        string path = Path.GetDirectoryName(currentPath);
        string absolutePath = System.IO.Path.Combine(path, relativePath);
        string dbConnectionString = string.Format("Data Source={0};Version=3;Pooling=True;Max Pool Size=100;", absolutePath);

        //string dbConnectionString = "Data Source=inventory_control.db";
        sQLiteConnection = new SQLiteConnection(dbConnectionString);

dbConnectionString 提供正确的当前路径。 上面的相对路径在我直接从 Visual Studio 运行时工作正常，但在我使用 WIX 创建安装程序时不起作用。它给出了一个 fatal error 。如何解决？

Answer 1

SQLite.Interop.dll: The file SQLite.Interop.dll needed to be installed along with the rest of the runtime files in order for SQLite to function properly.

There are two flavors of the file, x86 and x64 format. It is probably advisable to install both files in their respective folders:

Your installation folder hierarchy - mock-up:

• YourBinary.exe
• x86\SQLite.Interop.dll
• x64\SQLite.Interop.dll
• System.Data.SQLite.dll
• Etc...

Read-Write DB Location: And then your database should be stored in a writeable path (or you need to make the path writeable for regular users using custom ACL permissioning - which is never a great idea).

Exceptions: Obviously try - catch your database connection, update and access code to detect these kinds of issues.

1. 文件夹困惑:数据库文件夹中是否有数据库文件？它有点像 inventory_control.db 文件安装到主应用程序文件夹，而不是 Database 子文件夹？

   • 也许那个文件是由 application.exe 生成的在错误的文件夹中？
   • 或者您出于测试目的复制了主文件夹中的文件？

2. Hard-Coded Dev-Box Sins?:它在 Inventory Control.exe.config 中说了什么？ ?

   • 那里是否有可以覆盖您的代码值的相关设置？
   • 里面会不会有硬编码的开发箱问题？

3. Path Builder:我假设您在启动期间将来自应用程序的路径“消息框化”，以确保它们是正确的？我喜欢复制路径并执行 Start => Run并粘贴路径以查看它是否打开。按CTRL + C当消息框显示时。粘贴到记事本中。提取路径在Start => Run中试试.

   • string path = currentPath.Substring(0, currentPath.Length - 21); .硬编码文件名中的字符数来获取父目录路径不是很健壮吗？
   • 你能用 Path.GetDirectoryName(currentPath) 改进它吗？ ？
   • 或者甚至:string dir = currentPath.Substring(0,currentPath.LastIndexOf('\\'));

4. 附加调试器和调试二进制文件？:也许您可以安装调试二进制文件并附加到它们以进行调试，如下所述:wix c# app doesn't launch after installing .只是为了获得真正的逐步调试 session 。

5. 路径空间:该数据库连接字符串。它的路径需要引号吗？就像在“带空格的路径”中一样？您的 visual Studio 项目的路径中可能没有任何空格，但安装后路径中有空格。

源代码中的这个结构看起来很奇怪，为什么有必要？:

• <?define Inventory Control_TargetDir=$(var.Inventory Control.TargetDir)?>
