Hi,
The help for Type.InvokeMethod() has the following code sample for reading an indexed property:
===
//Get an indexed property value
int index = 3;
result = t.InvokeMember ("Item",
BindingFlags.Default |
BindingFlags.GetProperty,
null, c, new object [] {index});
Console.WriteLine ("Item[{0}] == {1}", index, result);
===
I have a similar situation in my own class but when I use very similar code I get a MissingMethodException. My member is an instance of a sub class of my class which has an indexer. Something like:
===
class Foo
{
public class Bar
{
private int[] prInts=new int[] {1, 2, 3};
public int this[int index] { return prInts[index]; }
}
public Bar Integers=new Bar();
}
===
Then I use a code like
===
Foo obj = new Foo();
Type t = typeof(Foo);
int index = 2;
object result = t.InvokeMember ("Item",
BindingFlags.Default |
BindingFlags.GetProperty,
null, obj, new object [] {index});
===
which results in a MissingMethodException.
The same problem applies for array fields.
Any ideas? Thanks in advance.

Guven,
Use the Instance binding flag. It says in the documentation that either
the Instance or Static member of the BindingFlags enumeration needs to be
specified.
Hope this helps.
