Brief introduction

Unity : U nity is a Microsoft team to develop lightweight, extensible dependency injection container, provides a good solution for loosely coupled application that supports constructor injection, injection property, method injection.

Inversion of Control : (Inversion of Control, abbreviated as the IoC), is used to subtractive coupling problems between the application, the upper layer of the lower layer dependent program proceeds to a third party to assemble the container.

Dependency injection : (Dependency Injection, abbreviated DI): We'll issue a request to the vessel, the process to obtain the object instance is called dependency injection.

achieve

Use NuGet packages Add a reference:

Enter Unity.Configuration search and download automatically add the required package (Unity.Container, System.Runtime.CompilerServices.Unsafe, Unity.Abstractions)

Such as:

Configuration files are as follows:

<? XML Version = "1.0" encoding = "UTF-. 8" ?> 
< Configuration > 
  < configSections > 
  <-! Association between handlers and configuration section defines the configuration element. -> 
    < sectionTop name = "Unity" type = "Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Unity.Configuration"  /> 
  </ configSections > 
  < Unity > 
    < Containers > 
      < Container > 
        <-! Type of object name, the name written MapTo object to inject the two parts are separated by commas, all one class, including the namespace, and second assembly name -> 
        < mapTo="命名空间,程序集名称">
          <lifetime type="singleton" />
          <!--Api接口-->
          <property name="Url" value="*****" />
          <!--用户名-->
          <property name="UserName" value="*****" />
          <!--密码-->
          <property name="UserPassword" value="*****"/>
        </register>      
      </container>
    </containers>
  </unity>
</configuration>

Profile Initialization:

var configFileNames the Directory.GetFiles = ( @ " D: \ folder a " , " * .config " );
 IF (configFileNames.Length =! . 1 ) 
{ 
 MessageBox.Show ($ @ " D: \ 'a folder 'which can be a profile, and now have a {configFileNames.Length} " );
  return ; 
} 

var filemap = new new ExeConfigurationFileMap 
{ 
 ExeConfigFilename = configFileNames [ 0 ] 
}; 
// read configuration information from the config file 
var configuration =ConfigurationManager.OpenMappedExeConfiguration (filemap, ConfigurationUserLevel.None);
 // get the configuration section specifies the name 
var Section = (UnityConfigurationSection) configuration.GetSection ( " Unity " );
 // create a container 
var _Uc = new new UnityContainer ();
 // load container 
section.Configure (_Uc);

Add a public member in VMMainWindow years, and with the [Dependency] mark at the top:

 [Dependency]
 public IPms Pms { get; set; }

With RegisterSingleton to register:

_Uc.RegisterSingleton<VMMainWindow>();

Finally, using the Resolve to resolve:

var vmMain = UC.Resolve<VMMainWindow>();

This will get to the contents inside the container.

Use NuGet packages Add a reference:

Enter Unity.Configuration search and download automatically add the required package (Unity.Container, System.Runtime.CompilerServices.Unsafe, Unity.Abstractions)

Such as:

Configuration files are as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
  <!--定义配置节处理程序与配置元素之间的关联。-->
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Unity.Configuration" />
  </configSections>
  <unity>
    <containers>
      <container>
        <!--type为对象的名称,mapTo为注入对象的名称 写法为用逗号隔开两部分，一是类的全部，包括命名空间，二是程序集名称-->
        <register type="命名空间,程序集名称" mapTo="命名空间,程序集名称">
          <lifetime type="singleton" />
          <!--Api接口-->
          <property name="Url" value="*****" />
          <!--用户名-->
          <property name="UserName" value="*****" />
          <!--密码-->
          <property name="UserPassword" value="*****"/>
        </register>      
      </container>
    </containers>
  </unity>
</configuration>

配置文件初始化：

var configFileNames = Directory.GetFiles(@"D:\某个文件夹", "*.config");
if (configFileNames.Length != 1)
{
 MessageBox.Show($@"D:\‘某个文件夹’里面必须只能一个配置文件，现在有{configFileNames.Length}个");
 return;
}

var fileMap = new ExeConfigurationFileMap
{
 ExeConfigFilename = configFileNames[0]
};
//从config文件中读取配置信息
var configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
//获取指定名称的配置节
var section = (UnityConfigurationSection)configuration.GetSection("unity");
//创建容器
var _Uc = new UnityContainer();
//载入容器
section.Configure(_Uc);

在VMMainWindow里添加公共成员，并用 [Dependency]在上方标记：

 [Dependency]
 public IPms Pms { get; set; }

用RegisterSingleton去注册：

_Uc.RegisterSingleton<VMMainWindow>();

最后使用Resolve去解析：

var vmMain = UC.Resolve<VMMainWindow>();

这样就获取到了容器里面的内容。
