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);

}

}
