How do you get the original type from a RuntimeType???

G

Guest

I have an application that is being passed objects which could either be an instance or a Type in the case of a Static Class

When you do the GetType on the object that was originally a Static class it gives you a type of "System.RuntimeType" as opposed to the orignal Static Class Typ

How do you get access to what type the the Orginal Static Class type was from the RuntimeType??

//Eg Routine......
Object[] objects = new Object[3]
Class1 class1 = new Class1("Class1")
objects[0] = class1
objects[1] = typeof(StaticClass)
objects[2] = typeof(StaticClass).FullName
//objects[1] = (Object)StaticClass

foreach (object o in objects

tr

Type type = o.GetType()
this.richTextBox1.Text += type.FullName+NL

if (type.FullName == "System.RuntimeType"

//??????? Here is what I need....How to Get the Orignal Static Class back????? from a
//System.RuntimeType???

else if (type.FullName == "System.String"

Type originalType = Type.GetType((string) o)
this.richTextBox1.Text += originalType.FullName+NL


catch (Exception ex

this.richTextBox1.Text += ex.Message+NL

You are getting the type of the type object. Instead try this:

foreach (object o in objects)
{
try
{
Type type = o is Type ? (Type) o : o.GetType();
this.richTextBox1.Text += type.FullName+NL;

if (type.FullName == "System.RuntimeType")
{
}

OK. I think I understood the question wrong. You want to get back an
instance of a class that you never created (StaticClass) in the first place.
Whatever you're trying to do, you should look into Reflection, specifically
MethodInfo class.
