找不到解决<T>方法UnityContainer

Question

据MSDN，使用UnityContainer类的Resolve<T>()方法如下：

var controller = container.Resolve<ManagementController>(); 

但是，我无法找到UnityContainer类定义方法。我只能看到这个：

public class UnityContainer : IUnityContainer, IDisposable 
{ 
    // Other methods 
    public object Resolve(Type t, string name, params ResolverOverride[] resolverOverrides); 
    public IEnumerable<object> ResolveAll(Type t, params ResolverOverride[] resolverOverrides); 
    // Other methods 
} 

我使用错误的软件包或其他东西吗？

这些是我安装的软件包。

using Microsoft.Practices.Unity; 
using Microsoft.Practices.Unity.Configuration; 

Answer 1

IUnityContainer.Resolve<T>()是一个扩展方法：

https://msdn.microsoft.com/en-us/library/microsoft.practices.unity.unitycontainerextensions(v=pandp.30).aspx

Answer 2

在Visual Studio中，把你的光标放在Resolve<T>方法，然后按F12键，它会去：UnityContainerExtensions

这是如果您需要它，扩展方法和代码是here。

Answer 3

它在UnityContainerExtensions类中。正如@CodingYoshi提到的，​​如果你做了F12或者定义，你会发现整个班级。

这是班级。
