.NET MAUI SQLITE DB Absolutes Pfad ⇐ C#

[Anonymous]

Ich habe eine SQLite -Datenbank in .NET MAUI < /p>
erstellt

Code: Select all

public static class Constants
{
private const string DBFileName = "SQLite.db3";
public const SQLiteOpenFlags Flags =
SQLiteOpenFlags.ReadWrite |
SQLiteOpenFlags.Create |
SQLiteOpenFlags.SharedCache;
public static string DatabasePath
{
get
{
return Path.
Combine(FileSystem.Current.AppDataDirectory, DBFileName);
}
}
}
< /code>
Die Anwendung wird bereits ausgeführt.This is the error I encounter:

Was ich ausprobiert habe, ist, dass ich < /p>
hinzufügeprivate const string DBDesiredPath = "``C:\\Users\\H00062147\\.android\\avd\\pixel_7_-_api_35.avd\\data``";

(Derzeit verwende ich einen Android -Emulator)
Und anstatt "Dateisystem.Current.Appdatadirectory" zu verwenden, habe ich diesen dbdesiderPath verwendet. Wird ein Fehler angezeigt.>
