我想从一个c#程序执行这个存储过程。

我在SqlServer查询窗口中编写了以下存储过程,并将其保存为 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

编辑:

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("\nTop 10 Most Expensive Products:\n");

            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();
        }
    }
}

这将显示异常无法找到存储过程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?

SqlServerAccess sqlAccess = new SqlServerAccess("your connection string");
var result = sqlAccess.Command().ExecuteNonQuery("StoredProcedureName");

最简单和直接的…

SqlCommand cmd = new SqlCommand("StoredProcedureName",con); // Just like you declared it
cmd.CommandType = CommandType.StoredProcedure; // an attribute related to the object
cmd.Parameters.AddWithValue("@value",txtValue.Text); // Parameter name and text source 

con.Open();
int rowAffected = cmd.ExecuteNonQuery();
con.Close();
using (var conn = new SqlConnection(connectionString))
using (var command = new SqlCommand("ProcedureName", conn) { 
                           CommandType = CommandType.StoredProcedure }) {
   conn.Open();
   command.ExecuteNonQuery();
}
using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
    conn.Open();

    // 1.  create a command object identifying the stored procedure
    SqlCommand cmd  = new SqlCommand("CustOrderHist", conn);

    // 2. set the command object so it knows to execute a stored procedure
    cmd.CommandType = CommandType.StoredProcedure;

    // 3. add parameter to command, which will be passed to the stored procedure
    cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));

    // execute the command
    using (SqlDataReader rdr = cmd.ExecuteReader()) {
        // iterate through results, printing each to console
        while (rdr.Read())
        {
            Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
        }
    }
}

****** Stored Procedure ******

CREATE PROCEDURE Addcontact
@CommandType VARCHAR(MAX) = NULL
AS
BEGIN
  IF (@CommandType = 'GetAllContactType')

END

用c#调用存储过程:

SqlCommand cmd = new SqlCommand("StoredProcedureName",con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@value",txtValue.Text);

con.Open();
int rowAffected = cmd.ExecuteNonQuery();
con.Close();
