ASP.NET MVC、Ninject、多个构造函数的每个请求单个实例

我试图通过将工作单元实例传递到我的存储库来实现工作单元模式。

相关代码来自Global.asax。

public class SiteModule : NinjectModule
{
    public override void Load() {        
       Bind<IUnitOfWork>().To<SqlUnitOfWork>()
                          .InRequestScope()
                          .WithConstructorArgument("connectionString", ConfigurationManager.ConnectionStrings["Entities"].ConnectionString);

       Bind<IProductRepository>().To<ProductRepository>();
       Bind<ICategoryRepository>().To<CategoryRepository>();
    }
}

存储库构造函数：

public class ProductRepository {
    IUnitOfWork unitOfWork;
    public ProductRepository(IUnitOfWork unitOfWork) {
        this.unitOfWork = unitOfWork;
    }
}

public class CategoryRepository {
    IUnitOfWork unitOfWork;
    public CategoryRepository(IUnitOfWork unitOfWork) {
        this.unitOfWork = unitOfWork;
    }
}

我想要的是每个请求最多创建 1 个 SqlUnitOfWork 实例，并传递到我的存储库中（通过它们各自的构造函数）。

IUnitOfWork 绑定上的 InRequestScope() 方法是否足够？如果不是我怎样才能实现这个目标？

Im trying to implement an unit of work pattern by passing an unit of work instance into my repositories.

Relevant code from Global.asax.

public class SiteModule : NinjectModule
{
    public override void Load() {        
       Bind<IUnitOfWork>().To<SqlUnitOfWork>()
                          .InRequestScope()
                          .WithConstructorArgument("connectionString", ConfigurationManager.ConnectionStrings["Entities"].ConnectionString);

       Bind<IProductRepository>().To<ProductRepository>();
       Bind<ICategoryRepository>().To<CategoryRepository>();
    }
}

Repository constructors:

public class ProductRepository {
    IUnitOfWork unitOfWork;
    public ProductRepository(IUnitOfWork unitOfWork) {
        this.unitOfWork = unitOfWork;
    }
}

public class CategoryRepository {
    IUnitOfWork unitOfWork;
    public CategoryRepository(IUnitOfWork unitOfWork) {
        this.unitOfWork = unitOfWork;
    }
}

What i want is that a maximum of 1 instance of SqlUnitOfWork is created per request and is passed into my repositories (via their respective constructors).

Is the InRequestScope() method on the IUnitOfWork binding enough? If not how can i achieve this?
