您需要使用 DependencyResolver 类在ASP.NET MVC。如果您正确连接您的容器 DependencyResolver.Current 将使用您的容器来解决的依赖关系。

You need to use DependencyResolver class in ASP.NET MVC. If you wire your container correctly DependencyResolver.Current will use your container to resolve the dependencies.

public class MustBeValidWarehouse : ValidationAttribute
{
    public override bool IsValid(object value)
    {
        if (value is string)
        {
            string warehouse = value.ToString();
            IInventService inventserv = DependencyResolver.Current.GetService<IInventService>();
            return (inventserv.GetWarehouses().Where(m => m.WarehouseId == warehouse).Count() != 0);
        }
        return false;
    }
}

在你的类的测试，你可以为 DepedencyResolver.Current 这样的模拟：

In your class tests you can provide a mock for DepedencyResolver.Current like this:

DependencyResolver.SetResolver(resolverMock);
