Reg - Reflection in array of objects

Hi,

I have a class which is array of classes. I need to traverse object of this class and do the following:
a. Instantiate object with total number of array size.
        e.g. student[] stu = new student[2];
b. Instantiate each array item in a object
        stu[0] = new student();
        stu[1] = new student();
c. Then will assign value to its properties. Like
        stu[0].name = "Test";
        stu[1].name = "Test1";

This is easy and done simply. But i want to do the same in Reflection, where object will be passed without memory allocation and also its instances. As follows:

student[] stu;
assignValue(stu);

public function assignValue(object studentObj)
{
     /*
        a. Instantiate object with total number of array size
        b. Instantiate each array item in a object
        c. assign value to its properties
      */

}

How to achieve this? I tried to set memory allocation and instantiation of each item, but am unable to set value to the object. Can anyone help me?

Thanks and Regards,
Mani

Try this:

using System;
using System.Reflection;

class student
{
private string name;

public string Name
{
get { return name; }
set { name = value; }
}
}

class Program
{
static void Main()
{
student[] stu;
assignValue(out stu);
Console.WriteLine(stu[0].Name);
Console.WriteLine(stu[1].Name);
Console.ReadKey();
}

public static void assignValue(out student[] studentObj)
{
Type t = typeof(student);
studentObj = (student[])Array.CreateInstance(t, 2);
studentObj[0] = (student)Activator.CreateInstance(t);
studentObj[1] = (student)Activator.CreateInstance(t);
PropertyInfo pi = t.GetProperty("Name");
pi.SetValue(studentObj[0], "Test", null);
pi.SetValue(studentObj[1], "Test1", null);
}
}
