才起床的时候,总是感觉还是比较不错的感觉,虽然不怎么情愿起来,先来BS下移动,一个破电话给我吵醒,为何呢?說啥要开奥运手机报,還不是赚钱啊,有种免费开,nnd……
废话不说了,这是骗还在床上写的,大家也就凑合着看,依然是上次的测试代码,贴一下。。
我忽然觉得新贴下测试结果也许大家会更感兴趣
test1 time past 00:00:00.9062500 克隆加动态委托 time past 00:00:00.7031250 test1 time past 00:00:01.4687500 克隆加动态委托 time past 00:00:00.7031250 test1 time past 00:00:00.8750000 克隆加动态委托 time past 00:00:00.6875000
这是连续的3次测试,嗯 ?发现一个问题,居然比直接执行要快!我也很怀疑,但是不知道为什么,如果你找出原因請告诉我,我觉得也许是克隆比new块一些吧 ,猜的,好了 看起来也许你开始迫不及待了,来看测试代码。
testclass clas = new testclass(); clas.test1(); clas.testdle(); clas.test1(); clas.testdle(); clas.test1(); clas.testdle();
这里是刚才的测试 main主题 大家看好了,我没作弊!
public class CTester : DesignPaterns.Reflection.Class ... { public CTester() ... { a = 10 ; } public void test1() ... { a = (a - 0.0001 ) * 1.0001 ; } private double a; public double geta() ... { return a; } public object Clone() ... { return this .MemberwiseClone(); } } public class CTestern : DesignPaterns.Reflection.Class ... { public CTestern() ... { a = 10 ; } public void test1() ... { a = (a - 0.0001 ) * 1.0001 ; } private double a; public double geta() ... { return a; } public object Clone() ... { return this .MemberwiseClone(); } }
一开始以为自定义类的构造时间长,所以特地分开了。结果还是一样的
public class testclass ... { public void testdle() ... { DateTime now = DateTime.Now; for ( int i = 0 ; i < 10000 ; i ++ ) ... { for ( int j = 0 ; j < 100 ; j ++ ) ... { CTester aTest = DesignPaterns.Reflection.DelegateReflection.Instance.GetObject < CTester > (); (aTest as DesignPaterns.Reflection.IReflection).InvokeMember( " test1 " ); } } TimeSpan spand = DateTime.Now - now; Console.WriteLine( " 克隆加动态委托 time past " + spand.ToString()); } public void test1() ... { DateTime now = DateTime.Now; for ( int i = 0 ; i < 10000 ; i ++ ) ... { for ( int j = 0 ; j < 100 ; j ++ ) ... { CTestern aTest = new CTestern(); aTest.test1(); } } TimeSpan spand = DateTime.Now - now; Console.WriteLine( " test1 time past " + spand.ToString()); } }
是的没错,完全反射执行。。
要看大类么?想看么? 嘿嘿 会给你看的

就是一个对对象缓存然后克隆的,demodemo 大家参考下就好了。

贴完了,有点多。。。。
也很乱,我知道,嗯,这里只对 void (void) 这样的函数进行了处理,本来还有个工厂的,不过暂时懒得写了,代码有点乱,大家也多担待,有什么问题,可以直接留言,如果少了那部分,如果我有贴漏的话无会补上,如果需要完整代码請留言,有空我会打包上来的。
希望大家喜欢她 :)
PS:那个速度有点问题 由于个人的粗心忘记修改了一个过程也就是直接运算的类的继承,直接的运算速度是
00:00:00.04750000左右。我这里加上了初始化也就慢了20倍但是相对以前的数百倍来说 ,确实是个好消息,不是么,如果除去初始化,我相信效果会让人满意的 !
