Resolve Type中构造函数传值

 1   class Test
 2     {
 3 
 4         private ITeacher _teacher;
 5         private IStudent _student;
 6         public Test(ITeacher tea, IStudent stu)
 7         {
 8             _teacher = tea;
 9             _student = stu;
10         }
11     }

2

 1    class Student:IStudent
 2     {
 3 
 4         public Student()
 5         {
 6             int i = 1;
 7         }
 8 
 9 
10         public int Age
11         {
12             get { throw new NotImplementedException(); }
13         }
14     }

3

 1    class Teacher:ITeacher
 2     {
 3 
 4         public Teacher()
 5         {
 6             int m = 0;
 7         }
 8         public int Age
 9         {
10             get { throw new NotImplementedException(); }
11         }
12     }

1             _container.RegisterType<IStudent, Student>(new ContainerControlledLifetimeManager());
2             _container.RegisterType<ITeacher, Teacher>(new ContainerControlledLifetimeManager());
3 
4             var viewModelTypeName = string.Format(CultureInfo.InvariantCulture, "App5.Test, App5, Version=1.0.0.0, Culture=neutral");
5             var viewModelType = Type.GetType(viewModelTypeName);
6 
7             _container.Resolve(viewModelType);

 

并没有注册过Test类

但是Resolve Test类的时候，Test构造函数中的参数会自动Resolve

即相当于调用Test构造函数前，会进行如下操作

1 _container.Resolve(ISutdent);

2 _container.Resolve(ITeacher);  

并将结果作为Test的构造函数参数传给Test

 

注意：如果Test中构造函数所传参数并没有通过注册，Test类的Resolve操作会报错
