带有依赖注入参数的Unity Call构造函数 [英] Unity Call constructor with parameter on Dependency Injection

问题描述

我创建了一个Unity Dependency Injection项目。在app config中创建了一个构造函数。错误被抛出为无法识别的元素'构造函数'。请帮助我。谢谢。

Hi,
I created a unity Dependency Injection project. Created a constructor in app config. The error thrown as "Unrecognized element 'constructor'. Please help me on this. Thank you.

<configuration>
  <configSections>
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration"/>
    <section name="unity1" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration"/>
  </configSections>
  <unity>
    <containers>
      <container>
        <types>
          <type type="Sample1.IDB,Sample1" mapTo="Sample1.oracle,Sample1"  name="Oracle"> </type>
          <type type="Sample1.IDB,Sample1" mapTo="Sample1.sql,Sample1"  name="Sql"></type>
          <type type="Sample1.IDB,Sample1" mapTo="Sample1.oracle,Sample1"  name="parOracle">
            <constructor>
              <param name="status" value="oracle" parameterType="System.String"/>
            </constructor>
          </type>
          <type type="Sample1.IDB,Sample1" mapTo="Sample1.sql,Sample1"  name="parSql">
            <constructor>
              <param name="status" value="sql" parameterType="System.String"/>
            </constructor>
          </type>
        </types>
      </container>
    </containers>
  </unity>
  <appSettings>
    <add key="Types" value="Oracle" />
  </appSettings>

</configuration>

< br $>


IUnityContainer container = new UnityContainer（）;



UnityConfigurationSection section =（UnityConfigurationSection）ConfigurationManager.GetSection（团结）;



这里它的抛出错误为无法识别的元素'构造函数'。

在应用程序配置中我更改了要注册的类型。然后它的抛出错误为无法识别的元素'寄存器'。它在类型和类型中正常工作。但是在添加构造函数后抛出错误。



实际错误是无法识别的元素'constructor'。（D：\Sample1 \ Sample1 \ Sample1 \bin\Debug \Sample1.vshost.exe.Config第14行）

IUnityContainer container = new UnityContainer();

UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");

here its throwing error as "Unrecognized element 'constructor'.
In app config I changed the Types to register. Then its throwing error as "Unrecognized element 'register'. Its working normaly in Types and Type. But after adding the constructor throwing an error.

Actual error is Unrecognized element 'constructor'. (D:\Sample1\Sample1\Sample1\bin\Debug\Sample1.vshost.exe.Config line 14)

推荐答案

use <register/> instead of type, there is no tag named type in unity

<register type="Sample1.IDB,Sample1" mapTo="Sample1.oracle,Sample1"  name="parOracle">
            <constructor>
              <param name="status" value="oracle" parameterType="System.String"/>
            </constructor>
</register>

enjoy :)
