            string sqlstr = @"Data Source=BE541554DB7E431;Integrated Security=True";
            using (SqlConnection con =new SqlConnection(sqlstr))
            {

                    SqlDataReader str = cmd.ExecuteReader();
                    while(str.Read())
                    {
                        Console.WriteLine(str[0]);
                    }
                    int count = int.Parse(cmd.ExecuteReader().ToString()) ;
                    Console.WriteLine(count);
                    Console.ReadKey();

Answer 1

//查看是否有行
bool isHasRows = str.HasRows;
Console.WriteLine(isHasRows.ToString());

Answer 2

LZ，你
string sqlstr = @"Data Source=BE541554DB7E431;Integrated Security=True";这里缺少了数据库名称了吧 ，试一下添加
AttachDBFilename=|DataDirectory|\数据库名.mdf

Answer 3

这是ADO。NET不是ADO，两个不一样的了
