问题描述
我正在使用EF Core在一个控制台项目中管理SQLite数据库文件。
I'm using EF Core, to manage a SQLite database file, in a console project.
创建数据库时,该文件是在bin中创建的文件夹,因此基本上是 MyProjectName\bin\Debug\netcoreapp1.1\FooDatabase.sqlite
。
When I create a database, the file is created in the bin folder, so basically MyProjectName\bin\Debug\netcoreapp1.1\FooDatabase.sqlite
.
我想更改它。
我尝试设置 Directory.SetCurrentDirectory
和 IHostingEnvironment.ContentRootPath
。没什么用。
I tried setting Directory.SetCurrentDirectory
and IHostingEnvironment.ContentRootPath
. Nothing works.
如何以编程方式设置应在其中创建数据库的目录?
How do I programmatically set the directory that the database should be created in?
推荐答案
在 Microsoft.Data.Sqlite
2.0(尚未发布)中, Directory.SetCurrentDirectory()$ c $
In Microsoft.Data.Sqlite
2.0 (not yet released), Directory.SetCurrentDirectory()
will do the trick.
直到我建议在您的连接字符串中使用绝对路径:
Until then I suggest using an absolute path in your connection string:
var builder = new SqliteConnectionStringBuilder(relativeConnectionString);
bilder.DataSource = Path.Combine(dataDirectory, bilder.DataSource);
var absoluteConnectionString = builder.ToString();
如果您真的想摆弄内部机制,则可以,但我不建议这样做:
If you really want to fiddle with the internal mechanics, you can, but I wouldn't recommend it:
// .NET Framework
AppDomain.CurrentDomain.SetData("DataDirectory", myDataDirectory);
// .NET Core
Environment.SetEnvironmentVariable("ADONET_DATA_DIR", myDataDirectory);
