Activator.CreateInstance和AssemblyCreateInstance性能测试

复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using HelloWorld.ServiceReference1;
using System.Globalization;
using System.Reflection;
using Interface;

namespace HelloWorld
{
class Program
{
static void Main(string[] args)
{
Stopwatch s = new Stopwatch();
Assembly a = Assembly.GetExecutingAssembly();

//foreach (var st in a.GetExportedTypes())
//{
// Console.WriteLine(st.Name);
//}

s.Reset();
s.Start();
Type t = a.GetType("HelloWorld.Test1");
Interface1 i2 = (Interface1)(Activator.CreateInstance(t));
Console.WriteLine((i2.Add(1, 2)));
s.Stop();
Console.WriteLine(s.Elapsed);

s.Reset();
s.Start();
Interface1 i = (Interface1)a.CreateInstance("HelloWorld.Test1");
Console.WriteLine((i.Add(1, 2)));
s.Stop();
Console.WriteLine(s.Elapsed);

}
}
public class Test1 : Interface1
{
public int Add(int a, int b)
{
return a + b;
}
}
public interface Interface1
{
int Add(int a, int b);
}
}
