C# - Deleting from SQL table with multiple column value checkings
I want to delete a row from an SQL table with multiple column value checking.  I know how to do with it a single column value:

        SqlConnection connection = new SqlConnection("YourDatabaseConnectionString");

        string sqlStatement = "DELETE FROM Customers WHERE ColumnID = @ColumnID";

        try{
            connection.Open();
            SqlCommand cmd = new SqlCommand(sqlStatement, connection);
            cmd.Parameters.AddWithValue("@ColumnID", "SomeValueHere");
            cmd.CommandType = CommandType.Text;
            cmd.ExecuteNonQuery();

        }
        finally {
            connection.Close();
        }

However, what is the syntax for multiple column value checking?  Also, how should I format the values if they are of Date (SQL) and Time7 (SQL) format?
