一印度学生Asp.net源码分享讨论

;       {
            string connectionString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"];
            SqlConnection connection = new SqlConnection(connectionString);
            connection.Open();
            //www.51aspx.com
            try
            {
                SqlCommand cmd = new SqlCommand();
                cmd = connection.CreateCommand();
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = query;

                return cmd.ExecuteScalar();
            }
            finally
            {
                if ( connection.State == ConnectionState.Open )
                    connection.Close();
            }
        }
    }
}

把常用的sql方法写成一个类，看起来非常清晰，功能简单。大家常用的的SqlHelper类既有过程又有sql语句实现的方法，让新手一看就晕(我现在偶尔晕晕)~~

通用函数类（字符串处理等）
