有时候我们需要在代码中动态生成一个sqllite数据库文件,可以按照以下代码完成,

 1 static void Main(string[] args)
 2 {
 3 string connString = string.Format("Data Source={0}", "test.db");
 4 MyContext context = new MyContext(new DbContextOptionsBuilder<MyContext>().UseSqlite(connString).Options);
 5 
 6 
 7 context.Database.GetDbConnection().ConnectionString = connString;
 8 context.Database.ExecuteSqlCommand(new RawSqlString(@"CREATE TABLE TagNames (
 9 Id INTEGER NOT NULL
10 CONSTRAINT PK_TagNames PRIMARY KEY AUTOINCREMENT,
11 Name TEXT NOT NULL,
12 Value TEXT
13 );
14 
15 "));
16 //TagName是我定义的一个表Context
17 context.TagNames.Add(new TagName() { Name = "new tag" });
18 context.SaveChanges();
19 Console.WriteLine("complete");
20 }
