Spring.NET - IList的构造函数参数
我正在尝试将 IList 注入构造函数，并想知道这是否可能，如果可以，有人可以启发我吗？事实上它要求一个类型转换器让我觉得我做不到。
我尝试过...
<object name="DataLayer.DataServices.IGetAccountDatabase" type="DataServices.LinqToEntities.EntityDataModel, DataServices.LinqToEntities" singleton="false"></object>
<object name="DataLayer.DataServices.IGetAccountMessage" type="DataServices.VMX.VmxModel, DataServices.VMX" singleton="false"></object>
<object name="DataLayer.DataServices.IDataService" type="DataServices.NavigationModel, DataServices" singleton="false">
<constructor-arg>
<list element-type="DataLayer.DataServices.IGetAccount, DataLayer" >
<idref object="DataLayer.DataServices.IGetAccountMessage"/>
<idref object="DataLayer.DataServices.IGetAccountDatabase"/>
</list>
</constructor-arg>
</object>
创建名为“DataLayer.DataServices.IDataService”的对象时出错，该对象在“文件[D:\Workspace\DataServices\Main\Source\DataServices\TestResults\2010-07-30 11_58_31\Out\Spring.xml”中定义]'：对象初始化失败：在初始化对象“DataLayer.DataServices”的属性“构造函数参数”期间，无法将托管列表元素“DataLayer.DataServices.IGetAccountMessage”从 [System.String] 转换为 [DataLayer.DataServices.IGetAccount]。 IDataService'。您是否注册了合适的类型转换器？
任何帮助表示赞赏。谢谢
I am trying to inject an IList into a constructor and want to know if this is possible and if so could someone enlightern me? The fact its asking for a type converter makes me think I can't do it.
I tried....
<object name="DataLayer.DataServices.IGetAccountDatabase" type="DataServices.LinqToEntities.EntityDataModel, DataServices.LinqToEntities" singleton="false"></object>
<object name="DataLayer.DataServices.IGetAccountMessage" type="DataServices.VMX.VmxModel, DataServices.VMX" singleton="false"></object>
<object name="DataLayer.DataServices.IDataService" type="DataServices.NavigationModel, DataServices" singleton="false">
<constructor-arg>
<list element-type="DataLayer.DataServices.IGetAccount, DataLayer" >
<idref object="DataLayer.DataServices.IGetAccountMessage"/>
<idref object="DataLayer.DataServices.IGetAccountDatabase"/>
</list>
</constructor-arg>
</object>
Error creating object with name 'DataLayer.DataServices.IDataService' defined in 'file [D:\Workspace\DataServices\Main\Source\DataServices\TestResults\2010-07-30 11_58_31\Out\Spring.xml]' : Initialization of object failed : Unable to convert managed list element 'DataLayer.DataServices.IGetAccountMessage' from [System.String] into [DataLayer.DataServices.IGetAccount] during initialization of property 'constructor argument' for object 'DataLayer.DataServices.IDataService'. Do you have an appropriate type converter registered?
Any help appreciated. thnx

我认为，如果您使用
id而不是name指定对象，它应该可以工作（通常使用 id 更好）。idref元素只能用于通过id引用对象。如果对象
DataLayer.DataServices.IDataService和对象DataLayer.DataServices.IGetAccountMessage和DataLayer.DataServices.IGetAccountDatabase是同一 xml 文件的一部分，您还可以使用idref的local属性。然后，在解析 xml 文件时，甚至在解析依赖项之前，您会收到错误消息。I think that if you specify the objects with an
idinstead of anameit should work (it is generally better to use id's). Theidrefelement can only be used to refer to objects by id.If the object
DataLayer.DataServices.IDataServiceand the objectsDataLayer.DataServices.IGetAccountMessageandDataLayer.DataServices.IGetAccountDatabaseare part of the same xml file, you can also use thelocalattribute ofidref. Then you get an error when the xml file is parsed, even before the dependencies will be resolved.
