Question

是否可以仅使用接口来解析使用泛型的对象。

类

public interface ItestObject<T>{ T Create();}
public class testObject<T> : ItestObject<T> where T: class, ICMSBasicTextData, new()
{
    public testObject(){}

    public T Create()
    {
        return new T();
    }
}

xml config

<alias alias="testObject_I" type="JMJoinery.ItestObject`1, JMJoinery" />
<alias alias="testObject_C" type="JMJoinery.testObject`1[[JMJoinery.CMS.Data.CMSBasicTextData, JMJoinery]], JMJoinery" />
<alias alias="CMSBasicTextData_I" type="JMJoinery.CMS.Data.ICMSBasicTextData, JMJoinery" />
<alias alias="CMSBasicTextData_C" type="JMJoinery.CMS.Data.CMSBasicTextData, JMJoinery" />

<register name="CMSBasicTextData_R" type="CMSBasicTextData_I" mapTo="CMSBasicTextData_C" />
<register name="test" type="testObject_I" mapTo="testObject_C" />

当我尝试解决时：

var o2 = JMJoinery.Global.Container.Resolve<ItestObject<ICMSBasicTextData>>();

发生此错误：

“无法转换类型为'JMJoinery.testObject 1[JMJoinery.CMS.Data.CMSBasicTextData]' to type 'JMJoinery.ItestObject的对象1 [JMJoinery.CMS.Data.ICMSBasicTextData]'。”

使用

Container.Resolve<ItestObject<CMSBasicTextData>>();

有效，但是可以仅使用界面解析

Container.Resolve<ItestObject<ICMSBasicTextData>>();

代替？

界面与实施

public interface ILookupDataReader<T>
{

    string LookupTypeID { get; }


}


public class CountryDataReader: ILookupDataReader<ICountry>
{


    string ILookupDataReader<ICountry>.LookupTypeID
    {
        get { return Enum.GetName(typeof(LookupTypeOptions), LookupTypeOptions.Country); }
    }
}

<强>注册

<alias alias="ILookupDataReader" type="Co.Application.Shared.Core.BusinessObject.ILookupDataReader`1,Co.Shared.Impl"/>
<alias alias="ICountry" type="Co.Application.Shared.Core.BusinessObject.Lookup.ICountry,                             Co.Shared.Impl"/>

<register type="ILookupDataReader[ICountry]" mapTo="Co.Application.Shared.Core.BusinessObject.Lookup.CountryDataReader,Co.Shared.Impl">
      <lifetime type="singleton"/>
    </register>
