c# 调用存储过程

本例调用存储过程的方法为:

设置SqlCommand.Comand为CommandType.StoredProcedure,并使用DataReader呼叫存储过程。

如下边调用Northwind数据库中的“Ten Most Expensive Products”存储过程代码:

using System.Data;
using System.Data.SqlClient;

namespace SqlStoredProcedure
{
    
class Program
    {
        
static void Main(string[] args)
        {
            SqlConnection thisConnection 
= new SqlConnection(
            
@"Data Source=scott;Initial Catalog=northwind;Persist Security Info=True;User ID=sa;Password=sa123");
            thisConnection.Open();

            SqlCommand thisCommand 
= thisConnection.CreateCommand();
            
//命令类型为存储过程
            thisCommand.CommandType = CommandType.StoredProcedure;
            
//存储过程名称
            thisCommand.CommandText = "Ten Most Expensive Products";

            
//执行存储过程
            SqlDataReader thisReader = thisCommand.ExecuteReader();

            
//显示结果
            while(thisReader.Read())
            {
                Console.WriteLine(
"\t{0}\t{1}", thisReader["TenMostExpensiveProducts"], thisReader["UnitPrice"]);
            }

            thisReader.Close();
            thisConnection.Close();
            Console.ReadLine();
        }
    }
