采用存储过程写的登录和查询（只为测试）

未采用三层

Sql 语句：

create procedure sp_Login3
@userName varchar(20),
@passWord varchar(20),
@msg int Output //表示输出参数
as
if(exists(select * from UserInfo where LoginId=@userName and [passWord]=@passWord))
begin
set @msg=1
end
else
begin
set @msg=0
end

cs后台代码，我这里没有分层：

string sql="server=;database=;uid=;pwd=";

//创建连接

using(Sqlconnection conn=new sqlconnection(sql)){

conn.open();

sqlcommand cpm=new sqlcommand("sp_Login3",conn); //"sp_Login3"存储过程名

com.commandType=CommandType.StoredProcedure;

            SqlParameter spname = new SqlParameter("@userName", SqlDbType.VarChar, 20);
            SqlParameter sppwd = new SqlParameter("@PassWord", SqlDbType.VarChar, 20);
            SqlParameter spint = new SqlParameter("@msg", SqlDbType.Int);
            spname.Value = TextBox1.Text;
            sppwd.Value = TextBox2.Text;
            spint.Direction = ParameterDirection.Output;
            com.Parameters.Add(spname);
            com.Parameters.Add(sppwd);
            com.Parameters.Add(spint);
            com.ExecuteNonQuery();
            int count = Convert.ToInt32(spint.Value);
            if (count > 0)
            {
                Context.Response.Write("登录成功");
            }
            else
            {
                Context.Response.Write("登录失败");
            }

}

查询：

      string sql = "server=;database=MyOffice;uid=;pwd=";
        SqlConnection conn = new SqlConnection(sql);
        conn.Open();

        SqlCommand com = new SqlCommand("Sp_sa2", conn);
        com.CommandType = CommandType.StoredProcedure;
        DataSet st = new DataSet();
        SqlDataAdapter dr = new SqlDataAdapter(com);
        dr.Fill(st);
        List<UserInfo> list = new List<UserInfo>();

        for (int i = 0; i < st.Tables[0].Rows.Count; i++)
        {
            UserInfo user = new UserInfo();
            user.Id = (int)st.Tables[0].Rows[i]["Id"];
            user.LoginId = (string)st.Tables[0].Rows[i]["LoginId"];
            user.UserName = (string)st.Tables[0].Rows[i]["UserName"];
            user.PassWord = (string)st.Tables[0].Rows[i]["PassWord"];
            user.Gender = (int)st.Tables[0].Rows[i]["Gender"];
            user.DepartId=(int)st.Tables[0].Rows[i]["DepartId"];
            user.RoleId = (int)st.Tables[0].Rows[i]["RoleId"];
            user.UserStateId = (int)st.Tables[0].Rows[i]["UserStateId"];
            user.SubmitTime = (DateTime)st.Tables[0].Rows[i]["SubmitTime"];
            list.Add(user);

        }
        GridView1.DataSource = list;
        GridView1.DataBind();
