I want to pass an additional parameter to the DBContext, like this
string myParam="xx";
string con="connenctionstring";
services.AddDbContext<IDbContext, DbContext>(
options =>options.UseSqlServer(con, myParam)
);
And in DBContext:
DbContext(DbContextOptions<AppDbContext> options, string myParam)
: base(options)
{
}
Somehow possible? Thanks
You cannot pass dependency to DbContext in this way.
First, create a class:
class MyClass
{
public string MyProperty { get; set; }
}
Then pass MyClass as a dependency to DbContext:
MyDbContext(DbContextOptions<MyDbContext> options, MyClass myParam)
: base(options)
{
//* Intentionally empty
}
Then register MyClass as a singleton to ServiceCollection:
services.AddSingletone(new MyClass { MyProperty = "xx" });
services.AddDbContext<MyDbContext>(options =>options.UseSqlServer(con));
