运行到(SqlDataReader reader = cmd.ExecuteReader())时报错

Question

class Program
{
static void Main(string[] args)
{
Console.WriteLine("请输入用户名：");
string admin = Console.ReadLine();
Console.WriteLine("请输入密码：");
string password = Console.ReadLine();
using (SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDBFilename=|DataDirectory|\Database1.mdf;Integrated Security=True;User Instance=True"))
{
conn.Open();
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "slect * Table1 where name='"+admin+"'";
using (SqlDataReader reader = cmd.ExecuteReader())
{
if (reader.Read())
{
string pw = reader.GetString(reader.GetOrdinal("Password"));
if (password == pw)
{
Console.WriteLine("登陆成功！");
}
else
{
Console.WriteLine("密码错误！");
}
}
else
{
Console.WriteLine("用户名不存在！");
}
}
}
}
Console.WriteLine("OK");
Console.ReadKey();
}
}
}
运行到using (SqlDataReader reader = cmd.ExecuteReader())时报语法错误，未处理Sqlexception
请问高手怎么解决，谢谢
我把cmd.ExecuteReader()插到错误语句前面，程序运行到这句的时候就会提前报错，错误与前面一致
把鼠标放在上面的时候下面会显示：
异常
System.Data.SqlClient.SqlException
System.InvalidOperationException
不知道为什么，谢谢

Answer 1

cmd.CommandText = "slect * Table1 where name='"+admin+"'";SQL语句好像写错了,改为:cmd.CommandText = "select * from Table1 where name='"+admin+"'";

Answer 2

多个对象使用using，必须要先声明对象，然后再使用，你现在using外面声明一下要用的对象，试试看
