SqlConn.Open();
        string Delete = "DELETE FROM BagenTablo";
        SqlCommand komut = new SqlCommand(Delete, SqlConn);

If the original db in your project has a data so every time when you build your project or debug it the visual studio copy the original db file into output folder

you can open MDF file in your project and right click on db in server window, then click New Query
type and execute this query
TRUNCATE TABLE BagenTablo
