Question

我在我的项目中设置了unity，它正在为没有实现构造函数注入的对象工作。问题是现在我有一个对象需要一个自定义对象作为构造函数参数。我在下面设置了配置，这个错误告诉我 “TypeConverter无法从System.String转换”

<unity>    
  <typeAliases>    
    <typeAlias alias="TransactionRepositoryInterface" type="Ib.TransactionViewer.DataAccess.ITransactionRepository, Ib.TransactionViewer.DataAccess" />    
    <typeAlias alias="TransactionRepositoryToUse" type="Ib.TransactionViewer.DataAccess.TransactionRepository, Ib.TransactionViewer.DataAccess" />    
  </typeAliases>
  <containers>    
    <container>    
      <types>    
        <type type="TransactionRepositoryInterface" mapTo="TransactionRepositoryToUse">    
          <lifetime type="singleton" />    
          <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">    
            <constructor>    
              <param name="TransactionProcessor" parameterType="Ib.TransactionViewer.DataAccess.TransactionProcessor, Ib.TransactionViewer.DataAccess">    
                <value value="Ib.TransactionViewer.DataAccess.TransactionProcessor" type="Ib.TransactionViewer.DataAccess.TransactionProcessor, Ib.TransactionViewer.DataAccess" />    
              </param>
            </constructor>     
          </typeConfig>    
        </type>    
      </types>
    </container>    
  </containers>    
</unity>

我不确定，但我认为团结正试图使用价值

Ib.TransactionViewer.DataAccess.TransactionProcessor

as String。

也许你应该写一些类似的东西：

    <unity>    
  <typeAliases>    
    <typeAlias alias="TransactionRepositoryInterface" type="Ib.TransactionViewer.DataAccess.ITransactionRepository, Ib.TransactionViewer.DataAccess" />    
    <typeAlias alias="TransactionRepositoryToUse" type="Ib.TransactionViewer.DataAccess.TransactionRepository, Ib.TransactionViewer.DataAccess" />    
  </typeAliases>
  <containers>    
    <container>    
      <types>    
        <type type="TransactionRepositoryInterface" mapTo="TransactionRepositoryToUse">    
          <lifetime type="singleton" />    
          <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">    
            <constructor>    
              <param name="TransactionProcessor" parameterType="Ib.TransactionViewer.DataAccess.TransactionProcessor, Ib.TransactionViewer.DataAccess">    
                <dependency />    
              </param>
            </constructor>     
          </typeConfig>    
        </type>    
      </types>
    </container>    
  </containers>    
</unity>
