Zugriff auf IBM db2-Datenbank mit ASP Net 5

Question

Ich muss meine ASP Net 5-Anwendung mit einer IBM Db2-Datenbank verbinden.

fand ich diese nuget Paket:

https://www.nuget.org/profiles/IBMDB2EF

Und ich folgte diesem Tutorial:

https://www.ibm.com/developerworks/community/blogs/96960515-2ea1-4391-8170-b0515d08e4da/entry/sample_ef7_application_for_ibm_data_servers?lang=en

Aber das funktioniert nicht.

Mein project.json

"dependencies": { 
"EntityFramework.IBMDataServer": "7.0.0-beta1", 
. . . 

}

Mein Starup.cs

public void ConfigureServices (IServiceCollection Dienste) { . . .

 services.AddEntityFramework() 
      .AddDb2() 
      .AddDbContext<DB2.Models.Users.UserContext>(); 

     services.AddScoped<IUserRepository, UserRepository>(); 
    } 

Mein DbContext

using Microsoft.Data.Entity; 
using IBM.Data.Entity; 

namespace DB2.Models.Users 
{ 
    public class UserContext: DbContext 
    { 
     public DbSet<User> User { get; set; } 

     protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
     { 
      optionsBuilder.UseDb2(@"Server=x.x.x.x;Database=x;password=x;uid=x;"); 
      base.OnConfiguring(optionsBuilder); 
     }   
    } 
} 

Mein Repository

using System.Linq; 

namespace DB2.Models.Users 
{ 
    public class UserRepository: IUserRepository 
    { 
     private UserContext _context; 

     public UserRepository(UserContext context) 
     { 
      _context = context; 
     } 

     public void pass() 
     { 
      var x = _context.User.First();    
     } 
    } 
} 

Wenn führen Sie diese Linie "var x = _context.User.First();" Zeige mir diesen Fehler:

Answer 1

Ich sehe dich markiert db2400 - ist das ein IBM i oder iSeries? Wenn dies der Fall ist, hat es eine eigene Version von DB2. Wenn das Obige wahr ist, verwenden Sie, was mit IBM i Access für Windows geliefert wird, und fügen Sie einen Verweis auf Folgendes hinzu:

C: \ Programme (x86) \ IBM \ Client Access \ IBM.Data.DB2.iSeries.dll

Ihre Installation könnte sich in einem anderen Verzeichnis befinden. Dadurch erhalten Sie, worauf Sie zugreifen müssen.
