How do I get Array elements from Reflection C#

How do I get Array elements value from Reflection..

Here is the C# code..

I have 2 struc

Public struct Address {
public string city;
}

public struct Person {
public Address[] Experience;
}
Person p = new Person();
p.Experience = new Address[2];
p.Experience[0] = "Los Angeles";
p.Experience[1] = "NewYork";
Type personInfo = p.GetType();
FieldInfo[] fieldInfo = personInfo.GetF ields();

foreach(FieldIn fo info in fieldInfo) {
if (info.FieldType .IsArray) {
Object Temp = (Object)info.Ge tValue(sender);
int len = ((Array)Temp).L ength;

// Error here. Error is cannot convert Address type to Object type
Object[] a = (Object[])Temp;
// If I do like "Address[] a = (Address[])Temp;" then
it works...But this class is a
helper class for serialization like JSON. So Object can be any
type.

for (int i = 0; i < len; i++)
result = a[i].City;
}
}

Anyone have any better idea.
All I need is to get object field name and its value.

thanks in advance.

In this case I think you can use System.Array.Ge tValue().

You can cast to Array and then use Array.GetValue to get a value.

The reason your cast to object[] didn't work is that Person is a value
type, and array covariance is only in terms of reference types (so a
string[] can be cast to an object[], but an int[] can't).

Hi,

Thats what I was looking for. Thank you very much for the input both
Jon and Mattias.
Quick question.
How do I find FieldType is a custom class or struct other than system
generic types. I could use "System.String" , "System.Int 32" etc.. Any
shot cuts ? Temp I use dirty way. Type.namespace != "System"

thanks
regards,
achu.

I'm not entirely sure what you mean. If you give a very precise
definition of exactly what you want the criteria to be, I suspect
you'll find that translates into code fairly naturally.

hi Jon,

How do I differentiate built in C# data types (Int32, String, DateTime
etc..) and user defind data types (Eg. "Address Struct") using
reflection? My Idea is to get all custom defind struct and class.

thanks,
Achu.
