c# - NInject with Generic interface

I have defined one interface and one class:

public interface IRepository<T>
{
}

public class RoleRepository:IRepository<Domain_RoleInfo>
{
}

Inject here:

public RoleService
{
    [Inject]
    public RoleService(IRepository<Domain_RoleInfo> rep)
    {
        _roleRep=rep;
    }
}

How can I perform Dependency Injection With Ninject,say how to bind?

I have written a helper class as below, it works fine with non-generic interface.but how to refactor it support generic interface as above?

public class RegisterNinjectModule : NinjectModule
{
    public override void Load()
    {
        BindServices();
        BindRepositories();
    }

    private void BindServices()
    {

        FindAndBindInterfaces("RealMVC.Service.Interfaces", "RealMVC.Services");            
    }

    private void BindRepositories()
    {
        FindAndBindInterfaces("RealMVC.Repository.Interfaces", "RealMVC.Repositories");   
    }

    private void FindAndBindInterfaces(string interfaceAssemblyName, string implAssemblyName)
    {
        //Get all interfaces
        List<Type> interfaces = Assembly.Load(interfaceAssemblyName).GetTypes().AsQueryable().Where(x => x.IsInterface).ToList();
        IQueryable<Type> ts = Assembly.Load(implAssemblyName).GetTypes().AsQueryable().Where(x => x.IsClass);

        foreach (Type intf in interfaces)
        {
            Type t = ts.Where(x => x.GetInterface(intf.Name) != null).FirstOrDefault();
            if (t != null)
            {
                Bind(intf).To(t).InSingletonScope();
            }
        }
    }


}

This should work:-

Bind(typeof(IRepository<>)).To(typeof(Repository<>));

where:-

IRepository<> is an interface of the form:-

public interface IRepository<T> where T : class
{
 //...
}

Repository<> is a class of the form:-

public class Repository<T> : IRepository<T> where T : class
{
  //...
}

I hope this helps :-)
