--T-SQL不带参数
if exists(select * from sysobjects where name='SelectStu')
drop proc SelectStu
GO
create proc SelectStu
as
select * from student
GO


--c#
SqlCommand cmd = new SqlCommand("SelectStu",con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataReader dr = cmd.ExecuteReader();
            while(dr.Read())
            {
                Console.WriteLine(dr["LoginId"]);
            }

 

--T-SQL 带一个参数
if exists(select * from sysobjects where name='SelectStu')
drop proc SelectStu
GO
create proc SelectStu
@name varchar(50)
as
select * from student where loginid=@name
GO


--C#
SqlCommand cmd = new SqlCommand("SelectStu",con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("@name", "LiDifei");
            SqlDataReader dr = cmd.ExecuteReader();
            while(dr.Read())
            {
                Console.WriteLine(dr["LoginId"]);
            }


--T-SQL 有返回值
if exists(select * from sysobjects where name='SelectStu')
drop proc SelectStu
GO
create proc SelectStu
@name varchar(50),
@id int output
as
select @id=studentid from student where loginid=@name
return @id
GO


--C#
SqlCommand cmd = new SqlCommand("SelectStu",con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("@name", "LiDifei");
            cmd.Parameters.Add("@id",SqlDbType.Int);
            cmd.Parameters["@id"].Direction = ParameterDirection.Output;
            cmd.ExecuteScalar();
            Console.WriteLine(cmd.Parameters["@id"].Value);

//以前写过的一个调用存储过程的方法

                SqlCommand cmd = new SqlCommand("proc_reg", conn);
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add("@id",SqlDbType.Int);
               如果是id是字符型的话,必须把输出长度写上,输入参数可以不用写长度,但是输出参数必须写上长度.

                cmd.Parameters.Add("@id",SqlDbType.navchar,50);
                cmd.Parameters["@id"].Direction = ParameterDirection.Output;
                cmd.Parameters.AddWithValue("@LoginPwd",Pwd);

                cmd.Parameters.AddWithValue("@FaceID",FaceID);
                cmd.Parameters.AddWithValue("@Sex",Sex);

                cmd.Parameters.AddWithValue("@Name",Name);
                cmd.Parameters.AddWithValue("@starId",starId);
