Dynamic Method Invocation

One very useful feature related to Reflection is the ability to create objects dynamically and call methods on them.
note : Class1.cs has methods which will be dynamically invoked at runtime from the DynaInvoke.cs

Class1.cs

using System;
class Class1{
       public static String method1()
       {
           return "I am Static method (method1) in class1";
       }
       public String method2()
       {
           return "I am a Instance Method (method2) in Class1";
       }
       public String method3(String s)
       {
          return "Hello " + s;
       }
}
save this file as Class1.cs and Compile c:/>csc /t:library Class1.cs

DynaInvoke.cs

using System;
using System.Reflection;
class DynamicInvoke
{
public static void Main(String [] args)
{

String path = "Class1.dll"
Assembly a = Assembly.Load(path);

//Invoking a static method
Type mm = a.GetType("Class1");
String i = (String) mm.InvokeMember ("method1",BindingFlags.Default | BindingFlags.InvokeMethod,null,null,new object [] {}); Console.WriteLine(i);

//Invoking a non-static method
object o = Activator.CreateInstance(mm);
i = (String) mm.InvokeMember("method2",BindingFlags.Default | BindingFlags.InvokeMethod,null,o,new object [] {});
Console.WriteLine(i);

//Invoking a non-static method with parameters
object [] par = new object[] {"kunal"};
i = (String) mm.InvokeMember("method3",BindingFlags.Default | BindingFlags.InvokeMethod,null,o,par);
Console.WriteLine(i);
}
}

save this file as DynaInvoke.cs and Compile c:/>csc DynaInvoke.cs and run C:/>DynaInvoke
