Read unknown object properties

Question

Hi All, Have question i hope someone can help me with. Is there anyway to read an object that you dont know the type of? Basiclly i have an old application the source has been lost and the code was obfuscated:( Now we need to get a list of information from an object within this application. I have injected a DLL that accepts the object as a Object But my question is what do I do next? How can I export all information in that object without casting it to its original object type (which i can't do)? Here is the declaration for the class: public class O urOrders : CTRL+Click to open in new tab." href="http://www.aisto.com/roeder/dotnet/Default.aspx?Target=code://mscorlib:2.0.0.0:b77a5c561934e089/System.Collections.Generic.IEnumerator ">IEnumerator >, CTRL+Click to open in new tab." href="http://www.aisto.com/roeder/dotnet/Default.aspx?Target=code://mscorlib:2.0.0.0:b77a5c561934e089/System.Collections.Generic.IEnumerable ">IEnumerable >, IEnumerable , IEnumerator , IDisposable Thanks for any help!!

You should be able to get the current value of the properties of 'obj' like this: private void simpleButton1_Click(object sender, EventArgs e) { Type t = sender.GetType(); PropertyInfo[] pia = t.GetProperties(); string message = ""; foreach (PropertyInfo b in pia) { message += String.Format("Name : {0}, Value : {1}
", b.Name, b.GetValue(obj, null)); } MessageBox.Show(message); }

Seemed to work fine thank you! Just also found that there is an object dumper class that comes in: C:\Program Files\Microsoft Visual Studio 9.0\Samples\1033\CSharpSamples.zip thanks again for the help!!

hi, thanks for the reply. i just tried the below as an example. It does give me the name and type of property but not its value. What i was more thinking of is a way to pass the object and that object is printed kinda like this: Object [0]=>String Value: [0]"Hello World" [1]=>Method [2]=>String[] Value: [0] "Val 1" [1] "Val 2" [2] "Val 3" [3]=>Object Value:[0] So like a snapshot of what the data in the specfic instance of that class. Thanks again! private void simpleButton1_Click(object sender, EventArgs e) { Type t = sender.GetType(); PropertyInfo[] pia = t.GetProperties(); foreach (PropertyInfo b in pia) { MessageBox.Show(b.ToString()); } }

Well, you might be able to use reflection. If 'obj' is an instance of the lost class, then you could get the Type object from: Type t = obj.GetType(); PropertyInfo[] pia = t.GetProperties(); and work from there.
