在 WinRT 上创建新的 SQLite 数据库？

Question

I want to create a new database from C# code in my WinRT app. I searched the Web and the way to do that appears to be the SQLiteConnection.CreateFile() method. However, that method does not exist in the SQLite namespace, at least in the WinRT version. I installed SQLite using the NuGet packge name "sqlite-net" and included the sqlite3.dll into my project. I do see properly methods like CreateTable(), Query(), etc. but not CreateFile(). Where is it? Or does the WinRT package use a different method for creating database files from code?

Answer 1

var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.Create | SQLiteOpenFlags.ReadWrite);

我是怎么做到的。

Answer 2

One of the times where Microsoft provides a straightforward example:

https://docs.microsoft.com/en-us/windows/uwp/data-access/sqlite-databases

 await ApplicationData.Current.LocalFolder.CreateFileAsync("sqliteSample.db", CreationCollisionOption.OpenIfExists);
 string dbpath = Path.Combine(ApplicationData.Current.LocalFolder.Path, "sqliteSample.db");
 using (SqliteConnection db =
    new SqliteConnection($"Filename={dbpath}"))
{
    db.Open();

    String tableCommand = "CREATE TABLE IF NOT " +
        "EXISTS MyTable (Primary_Key INTEGER PRIMARY KEY, " +
        "Text_Entry NVARCHAR(2048) NULL)";

    SqliteCommand createTable = new SqliteCommand(tableCommand, db);

    createTable.ExecuteReader();

Because depending on how you add sqlite to a UWP project, not having createfile() available is still an issue in 2021.
