c#-Reflective Knowledge points

1. Reflection is based on Sytem.type, and many of the methods inside are System.Reflection .

  
 

   
  

  
MethodInfo[] tt= t.GetType().GetMethods(); //t是string的实例，获得string类型的所有方法，这里面的GetMethods有个BindingFlags枚举类型，写了很多 常用的需要的类
   
  

  
foreach (var item in tt) {
   
  

  
Console.WriteLine(item.ToString()); 
   
  

  
 } 
   
  

  
Console.ReadKey();
  
 

2. Assembly-based reflection

 
    
  
 
     
   
assembly   =    assembly   load    "mscorlib,2.0.0.0.0,b77acu87d987asdf98"     //the token value here is casually written   
 
     
   
  type  Span class= "pun" >[]  types  =   objassembly   gettypes    
 
    
  

   
 

    
  

  
Assembly objAss = Assembly.GetExecutingAssembly();
    
  

  
Type t = objAss.GetType("Reflection.car", false, true);//第一个false表示找不到时不引发异常，第二个true表示忽略大小写查找
    
  

  
  Span class= "Typ" >car  oo  =     ( car   activator  Span class= "pun".  createinstance   t     //creates an instance of a class based on the established type, because it is not until what is returned, so covarince is an object   
    
  

  
  Span class= "Typ" >methodinfo  mi  =   T   getmethod    "move"     //move is the method name in the car class   
    
  

  
var ismove = (bool)mi.Invoke(oo, null); // 调用MethodInfo的方法Invoke，核实方法move是不是在类oo中
    
  

  
if (ismove) {
    
  

  
Console.WriteLine("is move ");
    
  

  
}
   
 

one of the car is a class, the 3rd behavior I modified after the code, the original code directly for object, not too rigorous, although can also use, but so write more dead some
