如何在 C# 程序中执行存储过程 [英] How to execute a stored procedure within C# program

问题描述

我想从 C# 程序中执行这个存储过程.

I want to execute this stored procedure from a C# program.

我在 SqlServer 查询窗口中编写了以下存储过程并将其保存为存储1:

I have written the following stored procedure in a SqlServer query window and saved it as stored1:

use master 
go
create procedure dbo.test as

DECLARE @command as varchar(1000), @i int
SET @i = 0
WHILE @i < 5
BEGIN
Print 'I VALUE ' +CONVERT(varchar(20),@i)
EXEC(@command)
SET @i = @i + 1
END

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace AutomationApp
{
    class Program
    {
        public void RunStoredProc()
        {
            SqlConnection conn = null;
            SqlDataReader rdr  = null;

            Console.WriteLine("
Top 10 Most Expensive Products:
");

            try
            {
                conn = new SqlConnection("Server=(local);DataBase=master;Integrated Security=SSPI");
                conn.Open();
                SqlCommand cmd = new SqlCommand("dbo.test", conn);
                cmd.CommandType = CommandType.StoredProcedure;
                rdr = cmd.ExecuteReader();
                /*while (rdr.Read())
                {
                    Console.WriteLine(
                        "Product: {0,-25} Price: ${1,6:####.00}",
                        rdr["TenMostExpensiveProducts"],
                        rdr["UnitPrice"]);
                }*/
            }
            finally
            {
                if (conn != null)
                {
                    conn.Close();
                }
                if (rdr != null)
                {
                    rdr.Close();
                }
            }
        }
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World");
            Program p= new Program();
            p.RunStoredProc();      
            Console.Read();
        }
    }
}

这会显示异常Cannot find the stored procedure dbo.test.我需要提供路径吗?如果是，存储过程应该存储在哪个位置?

This displays the exception Cannot find the stored procedure dbo.test. Do I need to provide the path? If yes, in which location should the stored procedures be stored?

推荐答案

using (var conn = new SqlConnection(connectionString))
using (var command = new SqlCommand("ProcedureName", conn) { 
                           CommandType = CommandType.StoredProcedure }) {
   conn.Open();
   command.ExecuteNonQuery();
}
