Unity.ResolutionFailedException - 依赖关系解析失败
我有以下代码:
public static IEngine CreateEngine()
{
UnityContainer container = Unity.LoadUnityContainer(DefaultStrategiesContainerName);
IEnumerable<IStrategy> strategies = container.ResolveAll<IStrategy>();
ITraderProvider provider = container.Resolve<ITraderProvider>();
return new Engine(provider, new List<IStrategy>(strategies));
}
和配置:
<unity> <typeAliases>
<typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" />
<typeAlias alias="weakRef" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" />
<typeAlias alias="Strategy" type="ADTrader.Core.Contracts.IStrategy, ADTrader.Core" />
<typeAlias alias="Trader" type="ADTrader.Core.Contracts.ITraderProvider, ADTrader.Core" /> </typeAliases> <containers>
<container name="strategies">
<types>
<type type="Strategy" mapTo="ADTrader.Strategies.ThreeTurningStrategy, ADTrader.Strategies" name="1" />
<type type="Trader" mapTo="ADTrader.MbTradingProvider.MBTradingProvider, ADTrader.MbTradingProvider" />
</types>
</container> </containers></unity>
我收到以下异常:
Microsoft.Practices.Unity.ResolutionFailedException:解决 依赖失败,类型=“ADTrader.Core.Contracts.ITraderProvider”, 名称=“”。异常消息是:当前构建操作(构建 key 构建密钥[ADTrader.MbTradingProvider.MBTradingProvider, null]) 失败:尝试读取或写入受保护的内存。这通常是一个 表明其他内存已损坏。 (策略类型 BuildPlanStrategy,索引 3) ---> Microsoft.Practices.ObjectBuilder2.BuildFailedException:当前 构建操作(构建键Build Key[ADTrader.MbTradingProvider.MBTradingProvider, null]) 失败: 尝试读取或写入受保护的内存。这通常是一个 表明其他内存已损坏。 (策略类型 BuildPlanStrategy,索引 3) ---> System.AccessViolationException: 尝试读取或写入受保护的内存。这通常是一个 表明其他内存已损坏。在 MBTCOMLib.MbtComMgrClass.EnableSplash(布尔 bEnable) at ADTrader.MbTradingProvider.MBTradingProvider..ctor() 在 BuildUp_ADTrader.MbTradingProvider.MBTradingProvider(IBuilderContext ) 在 Microsoft.Practices.ObjectBuilder2.DynamicMethodBuildPlan.BuildUp(IBuilderContext 上下文)在 Microsoft.Practices.ObjectBuilder2.BuildPlanStrategy.PreBuildUp(IBuilderContext 上下文)在 Microsoft.Practices.ObjectBuilder2.StrategyChain.ExecuteBuildUp(IBuilderContext context) --- 内部异常堆栈跟踪结束 --- at Microsoft.Practices.ObjectBuilder2.StrategyChain.ExecuteBuildUp(IBuilderContext 上下文)在 Microsoft.Practices.ObjectBuilder2.Builder.BuildUp(IReadWriteLocator 定位器、ILifetimeContainer 生命周期、IPolicyList 策略、 IStrategyChain 策略、对象 buildKey、对象现有)位于 Microsoft.Practices.Unity.UnityContainer.DoBuildUp(类型 t,对象 现有的,字符串名称) --- 内部异常堆栈跟踪结束 ---

有什么想法吗?
I have the following code:
public static IEngine CreateEngine()
{
UnityContainer container = Unity.LoadUnityContainer(DefaultStrategiesContainerName);
IEnumerable<IStrategy> strategies = container.ResolveAll<IStrategy>();
ITraderProvider provider = container.Resolve<ITraderProvider>();
return new Engine(provider, new List<IStrategy>(strategies));
}
and the config:
<unity> <typeAliases>
<typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" />
<typeAlias alias="weakRef" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" />

<type type="Trader" mapTo="ADTrader.MbTradingProvider.MBTradingProvider, ADTrader.MbTradingProvider" />
</types>
</container> </containers></unity>
I am getting the following exception:

Any idea?

MbTradingProvider.MBTradingProvider
的构造函数调用 COM 对象上的一个方法(从名称来看),MBTCOMLib.MbtComMgrClass.EnableSplash
。这个方法有一个bug,会导致写入错误的内存地址。The constructor of your
MbTradingProvider.MBTradingProvider
calls a method on a COM object (assuming from the name),MBTCOMLib.MbtComMgrClass.EnableSplash
. This method has a bug in it, causing wrong memory address to be written.
