How to retrieve an object's Property name/value pairs on a custom object? - asp.net

Question

I have a custom object with varying datatypes for each property.
I would like to be able to do something like:
public void evalCI(configurationItem CI)
{
foreach (PropertyInformation n in CI)
{
Response.Write(n.Name.ToString() + ": " + n.Value.ToString() + "</br>");
}
}
My custom object is:
public class configurationItem : IEnumerable
{
private string serial;
private string model;
private DateTime? wstart;
private DateTime? wend;
private Int32 daysLeft;
private string platform;
private string productVersion;
private string manufacturer;
private bool verificationFlag;
IEnumerator IEnumerable.GetEnumerator()
{
return (IEnumerator)GetEnumerator();
}
public string Serial
{
set { serial = value; }
get { return serial; }
}
public string Model
{
set { model = value; }
get { return model; }
}
public DateTime? Wstart
{
set { wstart = value; }
get { return wstart; }
}
public DateTime? Wend
{
set { wend = value; }
get { return wend; }
}
public Int32 DaysLeft
{
set { daysLeft = value; }
get { return daysLeft; }
}
public string Platform
{
set { platform = value; }
get { return platform; }
}
public string ProductVersion
{
set { productVersion = value; }
get { return productVersion; }
}
public string Manufacturer
{
set { manufacturer = value; }
get { return manufacturer; }
}
public bool VerificationFlag
{
set { verificationFlag = value; }
get { return verificationFlag; }
}
My expected output would be:
-Serial: 1234567
-Model: Mustang
-Wstart: 12/12/2005
-Wend: 12/11/2006
-DaysLeft: 0
-Platform: Car
-ProductVersion: GT
-Manufacturer: Ford
-VerificationFlag: true
At first I was getting an error that GetEnumerator() had to be implemented to use a foreach loop. The problem I keep running into is that all of the examples of Indexed Properties are of a single property with an indexable list, instead of an index for each property in the object. I was able to get intellisense to give me methods for PropertyInfo by adding:
IEnumerator IEnumerable.GetEnumerator()
{
return (IEnumerator)GetEnumerator();
}
However, the 2nd GetEnumerator() throws:
Compiler Error Message: CS0103: The name 'GetEnumerator' does not exist in the current context.
What am I missing here? How do I modify my object to give me the results I expect from evalCI()?

You don't need to implement IEnumerable. What you do need to do is use Reflection.
This is from memory, but I believe it would look like this:
foreach (PropertyInfo n in typeof(configurationItem).GetProperties())
{
Response.Write(string.Format("{0}: {1}<br/>", n.Name, n.GetValue(CI, null)));
}
This - the code as written - will also only give you public properties, and non-indexed properties (but it doesn't look like you have any indexed properties).
