Razorengine Performance Studies (reflection of the extended depth)

Let's start with a conclusion. 1) The razorengine is really slow, the compilation process is slow, and the compilation is still not suitable for a large number of repeated calls (one call can be accepted). 2) The relationship between Razorengine and ASP. Razor is unclear, so the conclusion here does not mean that ASP. NET MVC is slow. 3). NET 4.6 has a slightly higher reflection performance than. NET 2.0, and presumably the performance of the reflection assignment is raised from the native assignment of 1/5 to 1/4.
When testing razorengine here, an object property evaluator is implemented:

 
   
  
 
    
   
using  system   diagnostics    
  
    
   
using  razorengine    
  
    
   
using  razorengine   templating    
 
   
  

  
 

   
  

  
//脚本化的C#想写对还是有点麻烦的，还好Razor能给出有用的错误信息。
   
  

  
public class RazorPropertySetter<TEntity> where TEntity :class
   
  

  
 { 
   
  

  
 string PropertyName;
   
  

  

   
  

  
 bool Inited = false;
   
  

  

   
  

  
 private RazorPropertySetter(){ }
   
  

  

   
  

  
 public static RazorPropertySetter<TEntity> Create( string propertyName)
   
  

  
 {
   
  

  
 RazorPropertySetter<TEntity> rs = new RazorPropertySetter<TEntity>();
   
  

  
 rs.PropertyName = propertyName;
   
  

  
 return rs;
   
  

  
 }
   
  

  
 
   
  

  
 public void Set(TEntity entity , object value) 
   
  

  
 {
   
  

  
 /span>string   CacheKey  =   entity   gettype   ().  fullname    +     "--"    +    this   propertyname    
   
  

  
 DynamicViewBag viewBag = new DynamicViewBag();
   
  

  
 viewBag.AddValue("PropertyValue", value);
   
  

  
 if (Inited == false)
   
  

  
 { 
   
  

  
 string   template  =     "@{model."  +  propertyname  +     "= Viewbag.propertyvalue;}"    
   
  

  
 engine   razor   runcompile   ( template    CacheKey     typeof   tentity    entity   viewbag    
   
  

  
 Inited = true;
   
  

  
 }
   
  

  
 else
   
  

  
 { 
   
  

  
 Engine.Razor.Run(cacheKey, typeof(TEntity), entity, viewBag);
   
  

  
 }
   
  

  
 }
   
  

  
 }
  
 

  
 

   
  

  
 //测试用类
   
  

  
 public class TestData
   
  

  
 {
   
  

  
 public string Title { get; set; }
   
  

  
 }
  
 

  
 

   
  

  
 //测试代码
   
  

  
 TestData data = new TestData();
   
  

  
 data.Title = "V1";
   
  

  
 /span>razorpropertysetter  <  testdata  >   Settitle  =    razorpropertysetter  <  testdata  >.  create        
   
  

  
 Stopwatch watch = new Stopwatch(); 
   
  

  
 watch.Start(); 
   
  

  
 setTitle.Set(data, "V00"); 
   
  

  
 watch.Stop();
