The NuGet package using dapper currently supports. NET fromwork4.51 at its lowest level, so it feels more personal than ADO and easy to learn.

public void Search ()
{
var id = 1;
string query = "SELECT * from member where [email protected]";
var data = Dbhelper<member>. Query (query, new {id=id});

This. Response.Write ((object) data);
This. Response.End ();
}

The member above is a solid object, and if only the entity object member part of the field is required, you can selectively create

I record the province after the search everywhere.
