Enterprise Library 5 系列之1——Application Block的使用

标签：Resolve Library Application Unity Block Enterprise var theContainer

Application Block的对象、原型（Facades）与工厂

Application Block	Non-static Instance or Factory
Caching	ICacheManager
Cryptography	CryptographyManager
Data Access	Database
Exception Handling	ExceptionManager
Logging	LogWriter TraceManager
Security	ISecurityCacheProvider IAuthorizationProvider
Validation	ValidatorFactory ConfigurationValidatorFactory AttributeValidatorFactory ValidationAttributeValidatorFactory

 

服务定位器（Service Locator）

var writer = EnterpriseLibraryContainer.Current.GetInstance<LogWriter>();

var customerDb = EnterpriseLibraryContainer.Current.GetInstance<Database>("Customers");

 

访问容器

var theContainer = new UnityContainer() .AddNewExtension<EnterpriseLibraryCoreExtension>();

var writer = theContainer.Resolve<LogWriter>();

var customerDb = theContainer.Resolve<Database>("Customers");

 

需引用的程序集：

• Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Unity
• Microsoft.Practices.Unity

以上两种方法的优缺点，见https://docs.microsoft.com/en-us/previous-versions/msp-n-p/ff953191(v=pandp.50)
