0628 Method Parameters
<![CDATA[
Suppose we want to dynamically call string's Substring method.
Statically, this would be done as follows:
using System;
using System.Reflection;
using System.Collections.Generic;
class Program
{
static void Main()
{
Console.WriteLine("rntsoft.com".Substring(2));
}
}
Here's the dynamic equivalent with reflection:
using System;
using System.Reflection;
using System.Collections.Generic;
class Program
{
static void Main()
{
Type type = typeof(string);
Type[] parameterTypes = { typeof(int) };
MethodInfo method = type.GetMethod("Substring", parameterTypes);
object[] arguments = { 2 };
object returnValue = method.Invoke("rntsoft.com", arguments);
Console.WriteLine(returnValue);
}
}
