Export server-side function under one resource C#

[echoHU]

Hello! I want to share a mysql query function under one resource, I have got login.cs and mysql.cs and want to share this function to be able to use in login.cs

public DataTable ExecuteQueryWithResult(string sql)
{
	using (MySqlConnection conn = new MySqlConnection(connStr))
	{
		try
		{
			MySqlCommand cmd = new MySqlCommand(sql, conn);
			conn.Open();
			MySqlDataReader rdr = cmd.ExecuteReader();
			DataTable results = new DataTable();
			results.Load(rdr);
			rdr.Close();
			return results;
		}
		catch (Exception ex)
		{
			NAPI.Util.ConsoleOutput("DATABASE: [ERROR] " + ex.ToString());
			return null;
		}
	}
}

So the question is: How to use this function in other C# files under one resource?

Is there any function like TriggerEvent, etc?
