如何在c#程序中执行存储过程

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?

在我的例子中，我想在dataGridView中显示过程的结果:

using (var command = new SqlCommand("ProcedureNameHere", connection) {
            // Set command type and add Parameters
            CommandType = CommandType.StoredProcedure,
            Parameters = { new SqlParameter("@parameterName",parameterValue) }
        }) 
        {
            // Execute command in Adapter and store to dataset
            var adapter = new SqlDataAdapter(command);
            var dataset = new DataSet();
            adapter.Fill(dataset);
            // Display results in DatagridView
            dataGridView1.DataSource = dataset.Tables[0];
        }

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

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();

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();

请查阅Crane(我是作者)

https://www.nuget.org/packages/Crane/

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

还有一堆你可能会喜欢的其他功能。

这是一个存储过程的示例，它返回一个值并在c#中执行

CREATE PROCEDURE [dbo].[InsertPerson]   
-- Add the parameters for the stored procedure here  
@FirstName nvarchar(50),@LastName nvarchar(50),  
@PersonID int output  
AS  
BEGIN  
    insert [dbo].[Person](LastName,FirstName) Values(@LastName,@FirstName)  

    set @PersonID=SCOPE_IDENTITY()  
END  
Go  


--------------
 // Using stored procedure in adapter to insert new rows and update the identity value.  
   static void InsertPersonInAdapter(String connectionString, String firstName, String lastName) {  
      String commandText = "dbo.InsertPerson";  
      using (SqlConnection conn = new SqlConnection(connectionString)) {  
         SqlDataAdapter mySchool = new SqlDataAdapter("Select PersonID,FirstName,LastName from [dbo].[Person]", conn);  

         mySchool.InsertCommand = new SqlCommand(commandText, conn);  
         mySchool.InsertCommand.CommandType = CommandType.StoredProcedure;  

         mySchool.InsertCommand.Parameters.Add(  
             new SqlParameter("@FirstName", SqlDbType.NVarChar, 50, "FirstName"));  
         mySchool.InsertCommand.Parameters.Add(  
             new SqlParameter("@LastName", SqlDbType.NVarChar, 50, "LastName"));  

         SqlParameter personId = mySchool.InsertCommand.Parameters.Add(new SqlParameter("@PersonID", SqlDbType.Int, 0, "PersonID"));  
         personId.Direction = ParameterDirection.Output;  

         DataTable persons = new DataTable();  
         mySchool.Fill(persons);  

         DataRow newPerson = persons.NewRow();  
         newPerson["FirstName"] = firstName;  
         newPerson["LastName"] = lastName;  
         persons.Rows.Add(newPerson);  

         mySchool.Update(persons);  
         Console.WriteLine("Show all persons:");  
         ShowDataTable(persons, 14);
