Simple encapsulation and reconstruction of Autofac Container, autofaccontainer

For ease of use, the simple encapsulation of Autofac container is recorded as follows, which will be used or shared with you later. Welcome to discuss it!

1 using Autofac; 2 using Autofac. core. lifetime; 3 using Autofac. integration. mvc; 4 5 public static class ContainerManager 6 {7 private static IContainer _ container; 8 9 public static void SetContainer (IContainer container) 10 {11 _ container = container; 12} 13 14 public static IContainer Container 15 {16 get {return _ container;} 17} 18 19 public static T Resolve <T> (string key = "", ILifetime Scope scope = null) where T: class 20 {21 if (scope = null) 22 {23 // no scope specified 24 scope = Scope (); 25} 26 if (string. isNullOrEmpty (key) 27 {28 return scope. resolve <T> (); 29} 30 return scope. resolveKeyed <T> (key); 31} 32 33 public static object Resolve (Type type, ilifetimescript scope = null) 34 {35 if (scope = null) 36 {37 // no scope specified 38 scope = Scope (); 39} 40 return Scope. resolve (type); 41} 42 43 public static T [] ResolveAll <T> (string key = "", ilifetimes1_scope = null) 44 {45 if (scope = null) 46 {47 // no scope specified 48 scope = Scope (); 49} 50 if (string. isNullOrEmpty (key) 51 {52 return scope. resolve <IEnumerable <T> (). toArray (); 53} 54 return scope. resolveKeyed <IEnumerable <T> (key ). toArray (); 55} 56 57 public static T ResolveUnregistered <T> (I Lifetimescript scope = null) where T: class 58 {59 return ResolveUnregistered (typeof (T), scope) as T; 60} 61 62 public static object ResolveUnregistered (Type type Type, ilifetimescript scope = null) 63 {64 if (scope = null) 65 {66 // no scope specified 67 scope = Scope (); 68} 69 var constructors = type. getConstructors (); 70 foreach (var constructor in constructors) 71 {72 try 73 {74 var parameter S = constructor. getParameters (); 75 var parameterInstances = new List <object> (); 76 foreach (var parameter in parameters) 77 {78 var service = Resolve (parameter. parameterType, scope); 79 if (service = null) throw new ArgumentException ("Unkown dependency"); 80 parameterInstances. add (service); 81} 82 return Activator. createInstance (type, parameterInstances. toArray (); 83} 84 catch (ArgumentExcep Tion) 85 {86 87} 88} 89 throw new ArgumentException ("no suitable constructor found in all dependencies.
