0607 Reflecting and Activating Types
<![CDATA[
An instance of System.Type represents the metadata for a type.
Type Represents type declarations: class types, interface types, array types, value types, enumeration types, type parameters, generic type definitions, and open or closed constructed generic types.
You can get an instance of a System.Type by calling GetType on any object or with C#'s typeof operator:
using System;
using System.Reflection;
class Example
{
static void Main()
{
Type t = typeof(String);
MethodInfo substr = t.GetMethod("Substring",
new Type[] { typeof(int), typeof(int) });
Object result =
substr.Invoke("Hello, World!", new Object[] { 7, 5 });
Console.WriteLine("{0} returned \"{1}\".", substr, result);
}
}
using System;
using System.Reflection;
class Main
{
static void Main()
{
Type t1 = DateTime.Now.GetType(); // Type obtained at runtime
Type t2 = typeof(DateTime); // Type obtained at compile time
}
}
