C # programında saklı yordam nasıl yürütülür

Bu saklı yordamı bir C # programından yürütmek istiyorum.

Bir SqlServer sorgu penceresinde aşağıdaki saklı yordamı yazdım ve depolanmış1 olarak kaydetti:

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

Dapper Kullanımı. bu yüzden ben kimse yardım umuyoruz ekledi.

public void Insert(ProductName obj)
        {
            SqlConnection connection = new SqlConnection(Connection.GetConnectionString());
            connection.Open();

Lütfen Crane'ye bakın (ben yazarım)

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

Ayrıca beğenebileceğiniz başka özellikler de var.

Kodun DDL mi demek istiyorsun? Öyleyse, MSSQL'in hiçbir farkı yoktur. Yukarıdaki örnekler bunun nasıl çağrıldığını iyi göstermektedir. Sadece emin ol

CommandType = CommandType.Text

Yok Zarif burada cevap. Bu yüzden bir tane ekledim

using Dapper;
using System.Data.SqlClient;

using (var cn = new SqlConnection(@"Server=(local);DataBase=master;Integrated Security=SSPI"))
    cn.Execute("dbo.test", commandType: CommandType.StoredProcedure);
