通过IViewFactory
接口引导视图。我遇到了一个奇怪的问题,除了一个(
QuestionRadioBtnViewModel
)之外,我的ViewModels都被初始化了。在运行时尝试初始化viewModel时
var questionRadBtnVm = _viewFactory.CreateQuestionRadioBtnViewModel(answer.Text);
返回错误消息:
A first chance exception of type 'Castle.MicroKernel.Resolvers.DependencyResolverException' occurred in Castle.Windsor.dll
Additional information: Could not resolve non-optional dependency for 'Corp.Conveyancing.Desktop.ViewModels.Question.QuestionRadioBtnViewModel' (Corp.Conveyancing.Desktop.ViewModels.Question.QuestionRadioBtnViewModel). Parameter 'stringValue' type 'System.String'
然而,方法签名和构造函数匹配得很好
IViewFactory:
public interface IViewFactory
{
QuestionRadioBtnViewModel CreateQuestionRadioBtnViewModel(string textValue);
}
问题RadioBTNViewModel
public QuestionRadioBtnViewModel(IEventAggregator eventAggregator, string stringValue)
{
_stringValue = stringValue;
_eventAggregator = eventAggregator;
}

使用IViewFactory
的所有其他构造函数工作正常,数据传递没有问题。
我一定是遗漏了什么明显的东西?是我自己发现的。结果表明,不仅方法的签名必须匹配,而且传递的参数的名称也必须匹配
public QuestionRadioBtnViewModel(IEventAggregator eventAggregator, string stringValue)
stringValue
文本必须匹配
public interface IViewFactory
{
QuestionRadioBtnViewModel CreateQuestionRadioBtnViewModel(string stringValue);
}
