简单的存储过程调用demo

Use score       数据库
go

Create procedure aaaa       存储过程名

@sname nvarchar(20)        参数

as

select * from s where sname=@sname

在VS中调用

 private void button1_Click(object sender, EventArgs e)
        {

            string strcon = "server=.\\sqlexpress;database=score;Trusted_Connection=SSPI";  
            SqlConnection cn = new SqlConnection(strcon);
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = cn;
            cmd.CommandText = "aaaa";   存储过程名
            cmd.CommandType = CommandType.StoredProcedure;     类型
            SqlParameter pt = new SqlParameter("@sname", "阿迪");     获取参数
            cmd.Parameters.Add(pt);
            cn.Open();
            SqlDataReader rdr = cmd.ExecuteReader(); 读取
            if (rdr.Read())
            {
                MessageBox.Show(rdr[0].ToString() + rdr[1].ToString() + rdr[2].ToString()+rdr[3].ToString ());
            }

        }

最后结果是
