Structuremap ObjectFactory.GetAllInstances将空值插入列表

Question

我有一个非常简单的列表，我用Structuremaps ObjectFactory.GetAllInstances（）实例化。

private List<UserReleaseTime> _UserReleaseTimes = 
    ObjectFactory.GetAllInstances<UserReleaseTime>().ToList()

UserReleaseTime如下所示：

public class UserReleaseTime
{
    public string name { get; set; }
    public double totalReleaseTime { get; set; }
    public double withinReleaseHours { get; set; }
    public double outsideReleaseHours { get; set; }
}

创建集合后，似乎structmap添加了一个空值或空值的对象。反正有没有阻止这种情况发生？

更新 UserReleaseTime在Structuremap中注册，如下所示：

For<UserReleaseTime>().Use<UserReleaseTime>();
